4 Timing Analyzer Reference Guide Version 16-Nov-2018 Commands Analyzer.Arm Arm analyzer Analyzer.Arm The trace buffer is enabled for sampling, but the trace buffer is not cleared. The trigger unit is not initialized. An automatically switching on behalf on the realtime emulation commands offers the command Analyzer.AutoArm. Analyzer.AutoArm Analyzer.AutoInit Analyzer.state Analyzer.AutoArm Automatic arming Analyzer.AutoArm [ON OFF] The Analyzer.Arm command is automatically executed when the user program is started (on the ICE or ICD unit). After program break the analyzer is automatically switched into the OFF state. Previous records are not lost. The default state is OFF. Analyzer.Arm Analyzer.state Timing Analyzer Reference Guide 4

5 Analyzer.AutoInit Automatic initialization Analyzer.AutoInit [ON OFF] The Analyzer.Init command is automatically executed when the user program is started. Trace memory contents are erased before each program execution and previous records are no longer visible. The trigger unit is set to its initial state. All used counters are initialized and all used flags are set to OFF. In combination with the command Analyzer.AutoTEST the analyzer is able to generate continuous recording and displaying like an analyzer snapshot. Analyzer.Arm Analyzer.state Analyzer.AutoTEST Continuous measurement Analyzer.AutoTEST [ON OFF] If the CPU is running and the analyzer is in OFF state, the command Analyzer.Arm is executed. If the Analyzer.AutoInit function was activated, the command Analyzer.Init is executed prior to the ARM command, otherwise the trigger unit will be reset. After the analyzer has gone to the OFF state again (by analyzer trigger break or full trace in stack mode) all windows are updated and the measurement continues. The measurement is stopped, if a display window of the analyzer is entered. a.program data high A:0yxxxxxxx1 s.e if high.gt break if high.gt a.mode fifo a.autotest on a.autoinit off w.a.list ; program the analyzer ; true if bit zero is high ; sample if bit get high ; break analyzer for display ; standard mode ; select automatic test ; endless recording ; display the accesses Analyzer.state Analyzer.TEST Timing Analyzer Reference Guide 5

Without range the entry is searched in the complete trace memory. Without arguments the search continues to the next entry. The option Back reverses the direction of the search command. If executed from within an analyzer display window the command automatically tracks the window to the found position. The message line on bottom of the screen informs you about the searched area and the record number in which the value was found. If the newest record was reached, searching begins on top of the memory again. Another universal way for searching the occurrence of special items offers the command WindowFind. a.f (-1000.)--(-700.) my_dbus 20 a.f, nmi on nmi off a.f, a a 55 d 0 a.f ; search for data in ; limited record range ; search for rising edge of ; the NMI signal ; search for different data bytes ; in complete memory ; search for next occurrence Analyzer.List Analyzer.state Analyzer.Timing Timing Analyzer Reference Guide 7

8 Analyzer.GOTO Jump to entry Analyzer.GOTO <time> The command sets the tracking record to the specified record. If executed from within an analyzer display window, the command tracks the window to the given record. Analyzer.List Analyzer.state Analyzer.Timing Analyzer.Init Initialization Analyzer.Init The trace memory is erased and the trigger unit is returned to its initial setting (the counters, the flags and the levels are cleared). All user setups like analyzer mode or trace memory size, are not changed. Analyzer.state Timing Analyzer Reference Guide 8

Items: DEFault ALL TIme TIme.Back TIme.Fore TIme.REF TIme.Trigger TIme.Zero SPARE Default selections (see list below) The contents of the default selection can be configured with the command SETUP.ALIST. The default display for the timing display contains all external lines and all CPU control lines. Select all recorded data (superset of DEFault) Time marker (default Time.Fore) Time marker, relative time to previous record Time marker, relative time to next record Time marker, relative to reference point Time marker, relative to trigger point Time marker, relative to global reference Displays an empty block The message line on top of the screen calculates and displays continuously the current record number, the time difference between the current record and the reference record and the time difference between the current record and the zero reference time. Because of a limited area in the headline of the list window, the names of the channels may sometimes be cut and only the last characters are visible. Listing the current trace memory contents can only take place when the analyzer status is set to OFF. Otherwise the list window is frozen and displays previous memory contents. Timing Analyzer Reference Guide 10

11 Within the analyzer list window, a permanent click on the right mouse button offers additional commands like WinFind or WinPan. It is possible to print out the trace memory content on the system printer or saving the content in a file in a printable format with the command PRinTer and WinPrint. E::a.l Display the standard columns. This default can be configured with the command SETUP.ALIST. E::w.a.l /file Displays the last, with the command Analyzer.LOAD loaded trace memory contents C-R: +600ns C-Z: s cursor record number reference record to cursor time absolute time T::w.a.l all record a b c d ctrl ti.fore trigger -****** -****** T s s R ns s ns s ns s ns s ns s ns s s s C-Z: s C-R: ns T::w.a.l c0 c1 c2 %hl c3 c4 ti.ref record c0 c1 c2 c3 c4 ti.ref -****** -****** T LOW HIGH s R LOW LOW LOW LOW ns LOW LOW ns LOW LOW ns LOW LOW ns LOW LOW ns LOW LOW ns LOW LOW 3.034s Timing Analyzer Reference Guide 11

12 Each entry is classified as a record and numbered accordingly. Normally the most recent entry is numbered as -1. If a trigger point is available, the trigger point itself is marked with a "T" and its record number is 0. find-cp GOTO [TIMING] [config] [REF] [ZERO] F1 F2 F3 F4 F5 F6 Set ZERO ref.

13 Analyzer.LOAD Load reference buffer Analyzer.LOAD <file> The trace memory contents are loaded from the selected file and prepared for display. The same commands and options for displaying the current memory contents are used to display trace memory contents, except that the additional "/FILE" option must be entered. For searching an unknown stored trace memory content, use the wild card "*". The system offers a implicit directory window with all files extended with ".tad" E.g. "A.Load *". By clicking on the desired filename within the temporary directory window, will substitute the wild card character in the command line. The default extension of the file name is ".tad". Analyzer.state Analyzer.Mode Configuration Analyzer.Mode [<mode>] <mode>: Fifo Stack By this command the analyzer's operating modes can be selected. Fifo Stack If the analyzer is full, new records overwrite older records. The analyzer records always the last cycles before the break. If the analyzer is full it stops recording. The analyzer always records the first cycles after starting the trace. 50, 100, 200 Sample frequency in MHz. Analyzer.state Timing Analyzer Reference Guide 13

14 Analyzer.OFF Switch off Analyzer.OFF Both trace memory and the trigger unit are disabled. After this point the trace memory can be read and the trigger unit can be programmed. Analyzer.state Timing Analyzer Reference Guide 14

15 Analyzer.Program Program trigger unit Analyzer.Program [<file>] This command opens an editor window, which is used for programming the trigger unit. The program entry in the window is guided by softkeys and the online-help system. The trigger unit is programmed when leaving the window (MS-DOS) or double-clicking with the left mouse button (UNIX). After successful programming the filename will be displayed in the analyzer status window and in the stateline of the editor the message "(DRAFT)" disappears. The default filename is the file currently used by the trigger unit. The file name default extension is ".tap". This command can be executed by clicking on the trigger program name area in the analyzer state window. If the state of the analyzer is ARM and this command is executed, the state is switched to OFF before programming the trigger unit automatically. editing analyzer trigger program file not saved to disk not yet programmed file:..\demo\test1.tap mode: TRIGGER (EDITED) (DRAFT) line: 3 col: 1 E::w.a.p test1 data high a:0xxxxxxx1! s.e if high E:: decl glob inst loc instr F1 F2 F3 F4 F5 F6 F7 Analyzer.state Release Information in Release History Timing Analyzer Reference Guide 15

16 Analyzer.REF Set reference point Analyzer.REF <time> Determines the reference point from which the time differences will be calculated. In the message line the value C-R (cursor minus reference) is displayed continuously. The reference point default is always the latest record in the trace memory. Analyzer.List Analyzer.state Analyzer.Timing Analyzer.ReProgram Program trigger unit Analyzer.ReProgram [<file>] Programs the trigger unit of the analyzer with an existing program. The program should be error free, when using this command. To write an error free program, use the command Analyzer.Program. Analyzer.state Release Information in Release History Analyzer.RESet Reset analyzer Analyzer.RESet All functions of the analyzer are reset to its default settings. The trace memory and the trigger unit are cleared. All user defined presets are cleared too. Analyzer.state Timing Analyzer Reference Guide 16

17 Analyzer.SAVE Save trace buffer Analyzer.SAVE <file> Trace memory contents are stored to a file from which the contents can be recalled for display at a later time. This allows making a comparison between the previous and current records. The file name default extension is ".tad". Analyzer.state Timing Analyzer Reference Guide 17

18 Analyzer.state Display state Analyzer.state Display or modify operation options of the analyzer. This is the most important window for controlling the analyzer.

The command Pattern.Timing /FILE or Pattern.List /FILE displays this file. The file extension is ".PAC". Pattern.state Pattern.OFF Disable pattern generator Pattern.OFF The pattern generator is stopped. The pattern counter is not changed. Rearming will start the pattern generator again from this point. Pattern.state Timing Analyzer Reference Guide 44

45 Pattern.Program Program pattern generator Pattern.Program [<file>] This command opens an editor window, which is used for programming the pattern generator. The program entry in the window is guided by softkeys and the online-help system. The pattern generator is programmed when leaving the window (MS-DOS) or double-clicking with the left mouse button (UNIX). After successful programming the filename will be displayed in the pattern generator state window and the state line of the editor the message "(DRAFT)" disappears. The default filename is the file currently used by the pattern generator. The file name default extension is ".pat". This command can be executed by clicking on the pattern program name area in the pattern state window. If the pattern generator is in ARMed mode, the state is switched to OFF before programming the pattern generator. editing pattern program file not saved to disk not yet programmed file:..\demo\test1.pat mode: PAT (EDITED) (DRAFT) line: 3 col: 1 E::w.a.p test1 standby c:0 d:0 set c:1f E:: [ok] Set Delay Wait Restart STOP other F1 F2 F3 F4 F5 F6 F7 Timing Analyzer Reference Guide 45

46 Set DEFAULT STANDBY WAIT DELAY RESTART STOP RePeaT Defines the state of the pattern generator output lines and the bus trigger lines. A string is interpreted as multiple patterns. A mask is used to change only some bits in the sequence. All bit positions with don't care bits don't change the previous bits. Defines the default setup for Delay, Wait, BUS or NONE Defines the pattern at the reset state of the pattern generator Wait for trigger event Repeat previous state The pattern sequence starts again with the first line The pattern sequence stops here. It can be started by the commands INIT and ARM (or TEST) only. Repeat function. The next line or the next block will be repeated n times. Repeat functions may be nested. ( ) The block brackets are used to mark blocks for the repeat function. BUS.A..D A signal will be send over the corresponding bus trigger line BUSA..BUSD. Pattern.state Pattern.REF Set reference point Pattern.REF <time> Determines the reference point from which the time differences will be calculated. In the message line the value C-R (cursor minus reference) is displayed continuously. The reference point default is always the latest record in the trace memory. Pattern.List Pattern.state Pattern.Timing Timing Analyzer Reference Guide 46

47 Pattern.ReProgram Program pattern generator Pattern.ReProgram [<file>] Programs the pattern generator with an existing program sequence. The program should be error free, when using this command. To write an error free program, use the command Pattern.Program. Pattern.state Pattern.RESet Reset patttern generator Pattern.RESet All functions of the pattern are reset to its default settings. The pattern memory is cleared. Pattern.state Pattern.SAVE Save trace buffer Pattern.SAVE <file> Trace memory contents are stored to a file from which the contents can be recalled for display at a later time. This allows making a comparison between the previous and current records. The file name default extension is ".pac". Pattern.state Timing Analyzer Reference Guide 47

48 Pattern.state Display state Pattern.state Display or modify operation options of the pattern generator (PAT). This is the most important window for controlling the PAT. This window shows the number of traced records, the actual value of the counters and the current option settings. T::w.p.state state used program file OFF C:\HB\TEST1.PAT Arm records wait 8.

50 Pattern.TIMESCALE Define raster Pattern.TIMESCALE <time> This function defines the units for the time scale in the list and display window. On RESET the value is set to 100 ns. The command is only necessary if an external clock is used and the value is used as a correction factor. E.g. If the external clock is 2.5 MHz, then every pattern will last 400 ns. But without a TIMESCALE from 400 ns every pattern will be displayed as a 100 ns pattern.
