This makes the tool intuitive to learn and use. NEW: Control bars at the edge of the screen let you quickly display or hide tool windows, so you have the whole screen area for the optimal display of instrument layouts. Tailored to Different Use Cases CalDesk provides different ways of operation. When working at your desk or in the laboratory, you can operate CalDesk completely via mouse and drag & drop. For in-vehicle scenarios, CalDesk is optimized for keyboard-only operation and supports you with acoustic signals. Tabbed Pages and Tool Window You can easily organize your individual tasks in CalDesk by means of instrument panels (layouts) and tabbed pages. Any number of instrument panels can be created. Scalability CalDesk is scalable by means of additional software modules. Three modules are available: for control prototyping, automation, and ECU diagnostics. In addition, dspace provides a Variable Editor and an ECU flash programming tool which are smoothly integrated in CalDesk. You can use these software modules and utilities to tailor CalDesk s functionality to your precise requirements. You only invest in what is actually needed. 6

7 CalDesk CalDesk s user interface. Features such as tabbed pages, controlbars to quickly display and hide tool windows, shortcuts and a wide range of configuration options make the tool intuitive and easy to use. Organizing Projects and Experiments Each CalDesk project has its own project folder, and you can organize several experiments in one project. An experiment manages all the files and data relating to a task, such as instrument panels (layouts), measurement files, calibration data sets, reports, and devices. Custom files and tools can easily be integrated. You can use the project level above all the experiments to define global device configurations and integrate documents which are relevant to all experiments. Variable description files can also be shared so changes made to variable attributes like weak limits and calculated variables in one experiment are automatically available in other experiments in the project. Project Management Project Manager CalDesk s Project Manager gives you easy and intuitive access to all experiments and files associated with a specific project. You have many configuration options, for example, copying, removing, adding, and renaming. You can also configure the folder settings for the currently open project, for example, to specify where files are stored and which folders and files are displayed in the Project Manager. 7

8 Measurement and Calibration Software Project Management Filing According to Project Structure CalDesk creates a folder structure for each project on your file system. The folder structure in the Project Manager is similar to the one in Windows Explorer. CalDesk also supports fast configuration setup by automatic naming of projects and experiments. Later, all experiment-related files such as measurement data, data sets, and reports are automatically saved to the appropriate folder. This relieves you of a lot of administrative workload, giving you more time for the experiment itself. Selecting a project and experiment in CalDesk. Example folder structure in CalDesk s Project Manager. Wizard and Template Mechanisms You can speed up your task by using the wizard and template mechanisms. The wizard consists of a sequence of dialogs that guides you through the configuration steps and helps you avoid errors. Whatever your task defining a project or experiment, or adding a device to an existing experiment you get only the dialogs that are relevant. CalDesk uses XML templates to quickly and automatically create the complete folder structure for your projects and experiments, including various settings. Teamwork on Experiments CalDesk offers options for the easy exchange of projects and experiments between calibration engineers. For example, you can export experiments, save projects to a ZIP file, and open a complete project directly from a ZIP file. You can even share projects by simply copying the project folder in Windows Explorer. These features facilitate efficient teamwork on measurement, calibration, and diagnostic tasks. 8

9 CalDesk Selection of Variables In CalDesk, you can control and monitor variables interactively with the instruments on your layout. There is an easy-to-use variable browser with various filter and search options and a hierarchical representation to help you select variables. You can also create a list of selected variables, called a label list, and use it as a variable filter. Variables can be connected to instruments on layouts by drag & drop or keyboard. Instrumentation Automatic Connection of Variables to Instruments CalDesk can also assign and arrange instruments automatically: Just select the variables you want to measure or calibrate and press Enter. CalDesk automatically assigns the appropriate instrument and places it on the layout. You can also load predefined layouts with the correct connections between instruments and variables. NEW: Instrument Library With the new instrument library you can create layouts by dragging instruments to your working environment and assigning variables from the variable list via mouse or keyboard. Instruments you configured yourself can be stored in a library for future reuse. The instrument library, shown here with custom instruments preconfigured by the user. Calibration Concepts CalDesk features both offline and online calibration of ECU parameters. Offline calibration is based on calibration values mirrored on the PC and no connection to the actual ECU is required. Different calibration page concepts are supported, for ECUs with a single calibration page and for ECUs with two pages. Two-page concepts typically provide calibration data in a read-only memory (ECU flash or ROM), called the reference page, and a copy of the calibration data in the ECU RAM, called the working page. Parameter changes are only possible on the working page. Two-page concepts are fully reflected in CalDesk. This allows easy evaluation of step responses, quick comparison of parameter sets, and fast switching to a safe data set in the case of unexpected behavior. Apart from switching complete calibration pages, you can also assign reference values to individual variables. Calibration Starting Online Calibration To start online calibration, communication between CalDesk and the ECU via a dspace calibration interface must be initialized. When you go online, CalDesk compares the calibration values on the ECU to the calibration values on the host PC. If there is a difference, you can either upload the working and/or reference page from the ECU to CalDesk, or download the pages from CalDesk to the ECU. You can also skip the upload/download procedure if you want to perform measurement only. You can also upload or download only parameters that are connected to instruments in CalDesk. 9

10 Measurement and Calibration Software Calibration Reference and working page concept reflected in CalDesk. The calibration memory dialog lets you equalize the values on the ECU and the host. Calibrating Variables Calibrating variables means changing their values, for example, in the Alphanumeric Input instrument, the Bitfield Editor, the Slider instrument, or the Table Editor. You can also change parameters via a Push, On/Off or Check button. You can calibrate both scalar and multidimensional variables. Parameter changes can be made as physical values or as represented on the ECU, as hex, decimal, or binary values. Multiple parameter changes made on one or more instruments can be activated in one go. Editing 3-D Maps CalDesk has powerful features for editing 3-D maps: Interpolation when axis values are changed Display of maps and cross-references to maps that share the same axis Interpolation of all maps relating to the same shared axis XZ and YZ projections of 3-D maps Easy exchange of data with MS Excel Alphanumeric Input for calibrating scalar parameters. Tendency markers on the left indicate changes compared to the reference page. Bitfield Editor for changing individual bits of scalar parameters. The header information of the instrument is switched off. 10

11 CalDesk The Table Editor is designed for calibrating multidimensional parameters like maps and curves. Several maps can be assigned to one instrument, each on its own tab. Calibration The Knob and the Slider instrument allow parameters to be changed quickly by mouse or keyboard. NEW: Variable Array Instrument The Variable Array instrument provides numerous options for flexible and compact configuration of measurement and calibration instruments in a single instrument, for example, bitfields, edit fields, status LEDs, and new checkboxes and buttons. With further options such as an integrated value range check, the Variable Array provides a space-saving overview of all the relevant information at a glance. The Variable Array opens up many options for instrumenting variables. Elements like the new Push, On/Off and Check buttons and the Slider can be combined flexibly in the Variable Array instrument. Measuring Variables Typically, measurement variables are captured according to given rasters on an ECU or prototyping system. CalDesk also lets you perform polling measurement according to the PC timer. This is especially useful if there is no need to capture data synchronously to ECU tasks, for example, in order to save measurement bandwidth, or if no data acquisition service is implemented on the ECU. Capture rates for polling measurement are fully customizable. Not only measurement variables can be captured, but also calibration parameters. Selecting measurement rasters in CalDesk. Hardware polling allows measurement according to the PC timer. Measurement 11

12 Measurement and Calibration Software Measurement Correlation of Measurement Data and Periodic Resynchronization Measurement data captured from different sources such as ECUs, vehicle buses, and measurement modules are automatically synchronized and correlated. There are also mechanisms that periodically synchronize the time bases of associated hardware interfaces to prevent time drifts. Instruments for Measurements CalDesk provides various instruments for displaying measurement variables. You can connect measurement variables to a Plotter, Alphanumeric Display, Bar Display, Multistate LED, Bitfield Editor, Slider, and Gauge instrument. Plotter instrument for displaying analog and binary signals. The plotter s XY mode allows you to display multiple y-axis signals over one x-axis signal, overlapping or stacked. The signal plot is created by dropping a signal onto the x-axis. Gauge instrument. Alphanumeric Display. Status LEDs. Bar Display. Measurement Buffer CalDesk has a measurement buffer that lets you navigate through the data capture. Data can be analyzed offline and online, even while a measurement is running, in the same working environment. For example, you can start a measurement and pause the visualization at any time for data analysis. No measurement data is lost during the pause. The contents of the measurement buffer can be saved to a file even if no recording was previously started. Downsampling in the Plotter The Plotter also supports visual downsampling, in which the number of measurement data points that it displays is reduced as required, without affecting the number of data points that are actually recorded to disk. This means that even signals with very high sampling rates can be displayed during an ongoing measurement. A typical application is visualizing the envelope curve of torsional vibrations or the mean value of a noisy signal. 12

13 CalDesk Bookmarks You can set bookmarks during a measurement or recording to mark certain measurement points you want to analyse later. Bookmarks can be set either manually or automatically, for example, by definable trigger rules or on calibration page switches. The bookmark navigator gives you an overview of all the bookmarks in the cur- rent measurement or in the measurement files loaded. The visualization in the Plotter instrument is synchronized so when a bookmark is selected in the navigator, the correct time range is displayed automatically, and the selected bookmark is highlighted in the Plotter. You can also edit and search for bookmarks in the navigator. Measurement The dialog for defining trigger rules. Diverse downsampling options for visualization in the plotter. Bookmarks in Plotter instrument. The display of bookmarks is synchronized with the bookmark navigator. Bookmark navigator with edit and search options. 13

14 Measurement and Calibration Software Measurement Trigger Rules for Data Recording In CalDesk, you can define individual trigger rules to automatically start and stop data recording, including pre- and posttrigger times. During recording, measurement data is directly streamed to disk and saved to a file. Various export formats are available for exchanging measurement files with other tools, for example, CSV (MS Excel), MAT (MATLAB ), DAT or MDF. Define start and stop conditions for recording. Analysis of Measurement Data With CalDesk, you can analyse measurement data directly in the same experiment environment, no matter whether the data was recorded to a file or captured in the measurement buffer. Time Cursor Mechanism The time cursor mechanism allows the synchronous representation of data on all measurement and calibration instruments, for example, on a Plotter instrument and a Bitfield Editor, to evaluate the effect of parameter changes easily. Data Analysis in the Plotter The Plotter instrument provides a variety of features dedicated to data analysis: XY cursor Time cursor Zoom view and zoom undo Option to display all signals on top of each other without overlapping at the push of a button Scroll bar below display area for navigation Automatic calculation of maximum, minimum, mean value, and standard deviation over displayed time interval Diverse print options and option to create an image file Plotters can be used with or without synchronization (display over the same time interval or different ones) Display of signals over time or another signal (XY plot) Analyzing measurement data in the Plotter instrument. 14

15 CalDesk NEW: Compact Measurement Files With Key Information CalDesk provides an option for saving specific time intervals and signals displayed in the Plotter instrument to a new measurement file with or without data reduction. These measurement files contain only the information you really want and are more manageable in size. Recorded Data Layouts For analyzing recorded data, CalDesk provides Recorded Data Layouts. These can be created automatically by copying from standard layouts using the same instruments, graphical arrangement, and settings. In addition, predefined layouts can be used for data analysis, and you can assign measurement files without having to connect each variable individually. This feature allows you to quickly compare measurements during data analysis. You can of course also assign individual variables from different files to recorded data layouts and add time-offsets to align different measurements. Measurement Data Pool The Measurement Data Pool in the Tool Window gives you an overview of all the measurement files loaded in CalDesk and displays the variables and bookmarks associated with each file. Powerful filter options make it easy to find and show only the information which is relevant. Recorded Data Layouts in CalDesk and option to assign complete measurement files. Measurement Data Pool in CalDesk s Tool Window. Recorded variables and bookmarks are displayed. 15

16 Measurement and Calibration Software Calculated Variables Calculated Variables You can create new variables, called calculated variables, whose values are calculated from other variables in the associated description file. A formula editor helps you in defining the calculation method. Calculated variables can be connected to instruments in CalDesk and recorded in measurement files just like normal measurement variables. Suitable default properties on the associated configuration dialog make it possible to set up calculated variables quickly. Import and export options for calculated variables and formulas makes it easy to reuse them in different experiments and projects. ECU variables can also be modified or added to the variable description file loaded in CalDesk using the integrated Variable Editor (p. 25). Dialog for configuring calculated variables. NEW: You can access values in the past in order to implement filters, derivations, integrations or statistical functions such as mean values. Formula editor for defining a new calculation method. Exchange of Software Versions Assigning New Software Versions CalDesk makes it easy to exchange the software version (A2L and HEX files) associated with an ECU. Variables connected to instruments on layouts will automatically be referenced by the new variable description file. You can add any number of different software versions and switch between them. Prototyping applications are often characterized by fast iteration loops resulting in new software versions to be generated frequently. CalDesk notifies you when a new software version is available and lets you click to reload the associated variable description. The Project and Experiment Managers display all the software versions associated with an ECU or with a prototyping platform for you to activate. 16

17 CalDesk Copying, Renaming, and Exporting Different operations can be performed on data sets loaded in CalDesk. You can copy and rename data sets and export them as a CDF (Calibration Data Format as standardized by ASAM), DCM, or Microsoft Excel-compatible file. Data sets can be write-protected or defined as reference or working data sets. They can also be opened in a hex editor for viewing or changing their contents. Advanced Data Set Handling Data sets in CalDesk: Write-protected data sets are marked by a red icon, reference data sets by a blue R. The data set derived from the initial HEX file is marked M, standing for the master data set. Data Set Manager A data set contains the parameter values of calibration variables. You can manage data sets using the data set manager. For example, you can list parameters in a file, and compare or merge any number of data sets. When comparing data sets, you can show their differences only, and a label list comprising the variables which are different is generated automatically. Apart from label lists containing different variables, CalDesk also generates label lists containg new and missing parameters. Later on, lists can be used as variable filters for calibration tasks. You can also add calibration notes to individual parameters in the data set manager. CalDesk provides options to generate reports as XML, HTML or PDF files. You can easily adapt reports by means of customer-specific XML stylesheets. NEW: You can store data sets in a global pool to compare the data sets of different experiments or projects. CalDesk also lets you create data set containers for easy exchange of multiple data sets. The Data Set Manager lets you compare and merge multiple data sets. Differences, and new and missing parameters compared to a reference are highlighted. 17

The tool is based on flash projects that can be set up quickly to configure individual flash programming tasks. Using projects makes it easy and safe for you to flash program the ECU. dspace calibration interfaces DCI-GME1 and DCI-GSI1 provide fast USB communication that cuts the total time required for ECU flash programming to a minimum. Description Flash Kernel The dspace flash kernel is a small application that is loaded to the ECU s RAM by the ECU Flash Programming Tool and activated when ECU flash programming is started. The flash kernel consists of the ECU service and the drivers for the flash memory used. The integration of the flash functionality in a separate flash kernel instead of integrating it into the standard ECU application prevents from accidentially programming or erasing the ECU s flash memory. dspace provides consulting and engineering services to help you integrate the flash kernel into your ECU. Quick and easy ECU flash programming: You just have to select the flash project matching your flash programming task and press the Flash ECU button. 1) For ECU flash programming via diagnostic protocols, see the CalDesk ECU Diagnostics Module (p. 22). 27

28 Measurement and Calibration Software dspace XCP Service ECU service for measurement, calibration, bypassing, and ECU flash programming via XCP Key Features Measurement, ECU calibration, and function bypassing in parallel ECU flash programming Scalable according to functionality and resource consumption in the ECU Bypassing via dspace rapid prototyping systems Security and data consistency mechanisms for bypassing CAN, USB and Ethernet transport layer support Description Application Areas The Universal Measurement and Calibration Protocol (XCP) is the successor to the well established CAN Calibration Protocol (CCP). XCP is standardized by the Association for Standardisation of Automation- and Measuring Systems (ASAM). The dspace XCP service supports the transport layers for CAN, USB and Ethernet (UPD/IP and TCP/IP). It is designed for various use cases such as measuring ECU variables and calibration, and also for ECU flash programming in connection with CAN and USB. The dspace XCP on CAN and XCP on Ethernet service implementation is also dedicated to bypassing ECU functions using the dspace realtime prototyping platforms MicroAutoBox and AutoBox comprising DS1005 PPC boards as the external bypass system. Key Benefits Depending on the transport layer, the dspace XCP service covers various aspects of XCP, from measurement and ECU calibration to bypassing, and right through to ECU flash programming. Flexible configuration options make it possible to tailor the service implementation with regard to functionality and resource consumption in the ECU. For bypassing, dedicated mechanisms are provided to guarantee minimal latencies, data consistency, and automatic failure checking. In addition, you can run measurement, calibration, and bypassing tasks in parallel on the same ECU. In addition, it is possible to configure the XCP service on the ECU in such a way that two separate systems, like a calibration tool and a bypass system, can access the ECU independently of each other. dspace provides consulting and engineering services to help you integrate the dspace XCP service and flash kernels into your ECU. 28

29 dspace XCP Service Support of One and Two Service Instances With function bypassing, the service is typically configured for two instances, allowing two different client systems, like a calibration tool and a dspace prototyping system, to interface the ECU independently of each other. In other words, each client system can connect to or disconnect from the ECU, set up DAQ lists, and start or stop measurements regardless of the other client.

30 Measurement and Calibration Software dspace Calibration and Bypassing Service ECU service for measurement, calibration, bypassing, and flash programming Key Features Measurement, calibration, and ECU flash programming via DCI-GME1 and DCI-GSI1 Bypassing of ECU functions via dspace rapid prototyping systems, the DCI-GSI1, and DPMEM PODs Security and data consistency mechanisms for bypassing Scalable according to functionality and resource consumption in the ECU Description Application Areas ECU calibration based on memory emulators and on-chip debug interfaces typically requires a special service implementation on the ECU to measure data consistently and synchronously according to given ECU rasters. In addition, for function bypassing it is usually necessary to implement service calls (bypass hooks) in the ECU code to establish a synchronous communication between the ECU and the prototyping system. Using the dspace Calibration and Bypassing Service, you can run measurement, calibration, and ECU flash programming tasks via the DCI-GME1 and DCI-GSI1. The service is also designed for bypassing ECU functions by means of the RTI Bypass Blockset in connection with DPMEM PODs and the DCI-GSI1. Key Benefits The dspace Calibration and Bypassing Service allows you to perform measurement, calibration, and bypassing tasks in parallel. Flexible configuration options make it possible to tailor the service implementation on the ECU with regard to functionality and resource consumption. Special mechanisms for bypassing guarantee minimal latencies, data consistency and automatic failure checking. dspace provides consulting and engineering services to help you integrate the dspace Calibration and bypassing service and flash kernels into your ECU. 30
