1 USER GUIDE SLSC Prototyping Module SLSC PROTOTYPING MODULE POWER READY RADIAL SELECTOR CONNECTOR J1 CONNECTOR J2 Overview The SLSC is a prototyping module intended to help SLSC module developers quickly prototype designs. The module is Level-2 compatible, but can be Level-1 compatible if you configure the rear I/O signals properly. The SLSC features a MAX V CPLD as a module controller, which is pre-programmed to provide basic access to the board peripherals. The MAX V CPLD is divided into four banks, and the I/O for each is routed to its own region in the prototyping area. Each bank may have

2 independent voltage settings to allow the use of different digital standards supported by the CPLD. Custom circuitry in the prototyping area has access to 24 V and 3.3 V rails from the backplane, 5 V from the auxiliary power supply and corresponding bank power supply. Two of the regions of the prototyping area, Bank 1 and Bank 2, include connections to two 44-pin DSUB connectors in the front panel. A fifth region in the prototyping area, labeled RTI, provides additional space to access the upper rear I/O connectors. The peripherals designed into the SLSC board include two front panel LEDs (which follow the recommendations of the SLSC Design Guidelines), a 16-position rotary switch, four temperature sensors, and 17 ports 8-bit wide routed to their corresponding banks in the prototyping area. Additionally, to ease debugging and prototyping, a JTAG header compatible with Altera's USB Blaster pinout is populated on the board which allows you to program the CPLD with a custom design. A MICTOR connector exists between the CPLD and the SLSC connector to allow monitoring of the SLSC interface signals using a logic analyzer such as the one on NI VirtualBench.

Getting Started with the SLSC The SLSC can be inserted into an SLSC chassis and used the way it is shipped. Note The SLSC chassis and SLSC modules do not support hot plug-in. The entire chassis must be powered down when a module is installed or removed. 1. Ensure the CPLD power supplies are properly set. After taking the module out of its packaging, check that three jumpers are inserted between pins 5 and 10 of headers W2, W3, and W4. This ensures that the voltage is set to 3.3 V for the CPLD I/O banks 2, 3, and 4. 1 Quartus Design Software is offered in a variety of editions with different features and price ranges. Refer to the Quartus Software website for more information. SLSC User Guide National Instruments 3

4 Figure 1. Jumper Configuration 2. Install the module in the SLSC chassis. Power off the SLSC chassis and then insert the module into an available slot. If you are using the JTAG connector to program the CPLD or MICTOR cable to a logic analyzer, leave one empty slot to the right of the module for cable routing. Connect the cable(s) before inserting the module in the chassis. 3. Power up the chassis. As soon as the chassis is powered up, the power LED of the front panel of the SLSC should be lit green. The chassis will boot-up and start querying the slots for module presence. Once the module is detected, the Ready LED should be lit green. 4. Access the module's properties and physical channels. Use a host computer with LabVIEW and the NI-SLSC driver installed, and connected to the same network as the SLSC chassis. Open SLSC vi. This VI gives you access to the properties and physical channels that control the peripherals of the module. You can control the LEDs, read the value dialed in the rotary switch, and access all the DIO going to the prototyping area.

MICTOR Connector (for NI VirtualBench) 6. JTAG Header (CPLD Programming) Prototyping area The biggest area of the board is used for prototyping and is divided into five areas filled with thru-hole grids. These grids can be used with standard 0.10" headers, or may have wires or thru-hole components soldered to them. The prototyping area provides access to the majority of the CPLD I/O, the front and rear connectors, power supplies, and ground. Module controller Implemented in a MAX V CPLD, handles the communication with the SLSC chassis and controls the peripherals. Variable power supplies for CPLD Banks 2, 3, and 4 These power supplies can be set by the developer by placing the jumper of the corresponding header in the correct position. Note The jumpers must be set before powering the module and should not be changed once the system is powered. Front and rear connectors The connectors on the front panel and those facing the RTI area are the same as those recommended in the Switch Load and Signal Conditioning Module Design Specifications and in the SLSC Design Guidelines. Rotary switch The position of the rotary switch can be accessed by standard SLSC properties. Front panel LEDs The LEDs can be controlled through standard SLSC properties. Temperature sensors 4x ADT7310 are connected to the CPLD. SLSC User Guide National Instruments 5

7 Connectors The SLSC is designed with the front and rear connectors recommended in the Switch Load and Signal Conditioning Module Design Specifications and SLSC Design Guidelines. The module has the proper connectors for meeting Level-1 compatibility, but you must properly configure signals to and from these connectors in the RTI prototyping area. Refer to the Switch Load and Signal Conditioning Module Design Specifications for compatibility requirements. Prototyping Area Hole Arrays The following figure provides information about the arrays of holes found in the prototyping areas. These holes may be used for direct soldering of components and wires, or for attaching standard headers to connect to jumpers or secondary PCBs. Figure 4.

Electrical Features The Input Rails and Fuse The module takes its power from the 24 V and 3.3 V provided by the chassis. 3.3 V is only used for the VCCO of Bank 1 and other support circuitry such as the 40 MHz oscillator, flash memory, and thermal sensors. The rest of the banks and the core power used by the CPLD come from cascaded switcher regulators powered from an auxiliary 5 V supply connected to the 24 V rail. Banks 2-4 can be set to different values to allow you to use different digital standards available in the CPLD. All the 24 V, 5 V, and Banks 1-4 VCCOs are available in the prototyping area to be used by the support circuitry required by your design. You should make sure your design does not exceed the power limitations of these rails. As required by the Switch Load and Signal Conditioning Module Design Specifications, the 24 V power supply is protected by a 3.5 ma fuse. See the SLSC Bill of Materials for more information. 8 ni.com SLSC User Guide

9 Auxiliary 5 V Power Supply The programmable power supplies and the CPLD core power supply of 1.8 V are all powered by an auxiliary 5 V power supply which is powered from the 24 V provided by the SLSC chassis. This 5 V power supply is also available in the prototyping area. The power supply can support a maximum of 6 A. Variable Voltage Power Supplies The MAX V supports VCCIO of 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V in order to use several I/O standards. The SLSC has user-configurable power supplies for three of the four CPLD banks. The voltages are set by placing a jumper in the corresponding header connecting the pair labeled with the desired voltage. The jumper should be placed on the board before the module is inserted in the SLSC chassis. Once a voltage is set for a bank, all the signals on that bank need to use an I/O standard supported by that voltage. For more information about the supported I/O standards and rules to interconnect I/O standards with the MAX V CPLD, refer to Altera's MAX V Device Handbook. The voltages of all the banks are also routed to the prototyping area to allow the circuits built there to use it. The maximum current that can be withdrawn from each bank depends on the maximum current the source can provide, as well as the estimated current used by the CPLD. Bank 1 is powered directly from the SLSC chassis and, by SLSC Specification 1.0, the module shall not withdraw more than 400 ma. Banks 2-4 take their power from 24 V on-board power supplies and can provide up to 2 A. In addition to the limitations imposed by the current limits on the different rails on the module, you should also consider the power dissipation limitations as defined in the Switch Load and Signal Conditioning Module Design Specifications. Table 1. Bank Rail Available Voltages and Current Limits Bank Available Voltages Maximum Current V fixed, provided by the SLSC backplane 400 ma V, 1.5 V, 1.8 V, 2.5 V, 3.3 V 2 A V, 1.5 V, 1.8 V, 2.5 V, 3.3 V 2 A V, 1.5 V, 1.8 V, 2.5 V, 3.3 V 2 A Module Controller The SLSC Module Controller is implemented using Altera's MAX V 5M1270ZF256I5N. The CPLD is shipped pre-programmed with the compiled version of the Slsc12101Top.vhd design also included in the SLSC Module Development Kit. The controller's default image already implements the EdBlock.vhd design to handle SLSC Frames and the required compliance registers as described in Chapter 8 of the Switch Load and Signal Conditioning Design Specifications. Through the ED Mode, the controller can access the peripherals present on the board, such as the front panel LEDs, the front panel rotary switch, and 17 8-bit I/O ports routed from the CPLD to the prototyping area. SLSC User Guide National Instruments 9

10 CPLD Programming The SLSC has a header that directly connects to Altera's USB Blaster to quickly program the CPLD with a custom design. You can use the SLSC12101Top.vhd file provided in the SLSC Module Development Kit as a starting point for development. Front Panel LEDs The SLSC has Power and Ready LEDs as recommended in section 3.6 of the Switch Load and Signal Conditioning Design Specifications. The LEDs can be lit red, yellow, and green continuously or blinking so you can implement the information in Table 3-1 of that specification. The default module controller behavior implements the Power Solid Green and the Ready Solid Green as recommended in Table 3-1. The Leds.vhd component provided with the SLSC Module Development Kit implements an easy interface to control the LEDs through the NI.ReadyLedColor, NI.ReadyLedMode, NI.PowerLedColor, and NI.PowerLedMode properties described in the capabilities file included as part of the kit. Rotary Switch The 16-position, 4-bit rotary switch on the front panel is accessible from the CPLD. The value can be accessed through the SLSC API using the NI.RotarySwitch property. SI5356A Clock Generator The module has pads for you to add an SI5356A clock generator should you need more clocks in your design. This clock generator can provide up tp four different frequencies on eight pins. Each output clock has two pins. In the SLSC-12101, one pin is routed to a global clock pin of the CPLD, and another pin is routed to the prototyping area. For more information on the routing of these clocks to the prototyping area, refer to the pinout sections and the SLSC Schematic. Design Development, Characterization, and Debugging The SLSC was designed to provide an easy way to prototype SLSC modules in development. Use the resources provided by the SLSC chassis, the module controller, and the connectors to help you implement your design, to characterize some aspects such as power consumption and dissipation, as well as for increased visibility for diagnostics. Prototyping Area Most of the board consists of the prototyping areas, which are filled with hole arrays of 2.54 mm (0.100 in.) pitch. These are all plated holes to ease soldering. There are five main grid areas for prototyping: Bank 1, Bank 2, Bank 3, Bank 4, and RTI. Each bank gives access to signals of the corresponding bank on the CPLD as well as to the corresponding bank VCCO. Banks 1 and 2 also provide access to the front panel connectors. 10 ni.com SLSC User Guide

11 The RTI grid contains holes connected to the rear I/O connectors, XJ02 and XJ03, along with several grounds, access to the 24 V supply from the backplane, and two pairs of holes connected to each of the bank rails. Each of the five grids has its own coordinate system. Rows are numbered from top to bottom, and columns are marked with letters from left to right. Hole A1 is always at the top-left corner. These coordinates are referenced in this document. For a detailed assignment of the hole arrays, refer to the SLSC pinout sections of this manual. Power Consumption Validation To ease the validation of power consumption in the module, you can monitor the power rails. The 24 V and 3.3 V rails provided by the backplane go through bridge resistors that can be removed so that current measurements can be performed. Resistor R 16 connects the backplane 24 V rail to the module, and W1 provides two holes to connect a bypass cable for current measurement or an external power supply. The 3.3 V rail uses resistor R168 as the bridge and W6 as the bypass holes. Figure V Bridge Resistor and Bypass Holes The power supplies for banks 2-4 do not have a bridge resistor. Instead they are routed in such a way that they have a thick trace on the primary side of the board so it can be cut. Holes exist for bypass cables. A dotted line with a label of the bank it supplies power to indicates where the trace should be cut. See the following figures. Figure 7. Bank 2 Voltage Setting Header and Dotted Lines for Power Trace Cutting SLSC User Guide National Instruments 11

12 Figure 8. Bank 3 and Bank 4 Voltage Setting Header Logic Analyzer Connector A 43-pin MICTOR Connector is placed between the CPLD and SLSC Interface connector for direct monitoring of the signals using a logic analyzer. In addition to the SLSC signals, 17 debug lines are connected directly from the CPLD to the connector. In the shipping CPLD image, two of these lines are controlled by DIO ports, one line is a copy of the internal 40 MHz clock, and 14 lines are only driven to GND. You can use all 17 lines to monitor internal signals of your design. See pinout sections for more information on the signal routing to this connector. Description of the Module Controller HDL General Architecture The SLSC Module Controller instantiated in the MAX V CPLD is implemented in VHDL. The top-level file is Slsc12101Top.vhd. The design uses an instance of EdBlock (EdBlock.vhd) to handle the communication between the SLSC chassis and the Module Controller. The design features an SPI Channel selector which can be used for future SPI channel expansion in the SLSC architecture. This channel expansion can be used in this module to access temperature sensors in the prototyping area. 12 ni.com SLSC User Guide

You can use it to easily implement registers in your design by calling the RegisterRead and RegisterWrite functions declared in the PkgEdBlock.vhd file. You will only need to focus on implementing a digital circuit that converts these register accesses into useful control and monitor signals in your design.

All signals from the CPLD to the prototyping area are routed with 50 Ω characteristic impedance traces and have a 33.2 Ω series resistor places near the CPLD. All connections between XJ2 and the RTI prototyping area are routed with 50 Ω characteristic impedance without any series resistors. The connections between XJ3 and the RTI prototyping area with high current traces are capable of carrying 8 A each. For more information, refer to the SLSC Specifications, which can be found on ni.com/manuals. Hole Marking Codes Holes in the prototyping area are marked according to their purpose, as shown below. SLSC User Guide National Instruments 23

24 Table 12. Marking Codes to Identify the Holes in the Prototyping Area Unconnected Ground Signal Power Unconnected holes do not have any silkscreen marking. These holes can be used for any connections. An example of this kind of hole is M8 of Bank 1. Holes connected to ground are marked with a solid white square (represented in black in this document). An example of this type of hole is AD4 of Bank 2. Holes connected to a trace have a box around them. The box can be a rectangle around adjacent holes connected to traces. An example of this type of hole is C18 of Bank 3. An example of a rectangle enclosing adjacent holes are holes AB7 to AB9 of Bank 3. The rectangles have labels attached providing an indication of which signals these are. For example, C18 of Bank 3 is labeled CPLD(133) and holes AB7 to AB9 are labeled CPLD(134:136). Holes connected to power rails have a circle around them. An example of this hole is A23 of Bank 4, which is a hole connected to the 5 V rail. These may also have boxes around them to help with labeling. 24 ni.com SLSC User Guide
