Batch Mode Example : Tektronix files

SynaptiCAD products that can read Tektronix files and have the compare option added can run comparisons on files using batch mode execution. This makes it very fast to load successive Logic Analyzer captures and perform comparisons. This example shows a batch file that will compare a Tektronix logic analyzer file and a file that has been converted to SynaptiCAD.s btim format. The following code really only 3 lines of code and a lot of documentation. The code can be copied in to a *.bat file and executed:

echo off

                  

                  REM This batch file demonstrates how to do batch conversion/comparison with

                  REM WaveFormer Pro. Input is a golden reference file (reference.btim),

                  REM a filter file (reference_filter.tim) and a Tektronix file.

                  REM The filter file contains the comparison tolerances for each signal being compared.

                  REM The filter file was created by loading the reference file, changing all the signals

                  REM to compare signals and setting the comparison tolerances, then save as "Waveform filter".

                  REM

                  REM This bat file converts the Tektronix file to a btim file (our native file format).

                  REM Next it sets the filter file to set the compare tolerances, loads the reference file,

                  REM and compares the converted Tektronix btim file against the reference file.

                  

                  

                  set syncad=c:\SynaptiCAD\syncad.exe

                  set product=wfp

                  set basename=LMOList

                  set referencefile=reference.btim

                  set filterfile=reference_filter.tim

                  

                  echo This assumes that the files %basename%.vcd and %filterfile%

                  echo are in the current directory.

                  echo WARNING: in Windows 9x, this will launch two conversions

                  echo at once because batch files don't wait for subprocesses to

                  echo complete before they continue to the next step. This isn't

                  echo really a problem -- multiple copies of WaveFormer Pro can be

                  echo run at the same time -- as long as there is no dependency

                  echo between the first step and the second step. In our case,

                  echo the second invocation depends on the file %basename%.cbc

                  echo generated by the first step, so we've got a problem.

                  echo We're cheating here and putting a pause statement between the

                  echo two commands and leaving it up to the user to separate the

                  echo commands. In a real app you'd need to do something more clever.cc

                  echo .

                  

                  echo .

                  echo Converting %basename%.txt to btim format for use as compare file

                  %syncad% -p%product% --batch-mode --eval-perl-string twf::SetFilterFile(undef);

                  twf::OpenFile(qw(%basename%.txt),qw(TVECTOR_To_IF));

                  twf::SaveFile(qw(%basename%.btim),qw(IF_To_TIMBINARY));

                  

                  

                  echo Press ENTER when you think the conversion to BTIM format might be done

                  pause

                  

                  echo .

                  echo Now we invoke WaveFormer Pro to do the comparison

                  echo and display the results.

                  REM NOTES: that the argument to CompareFile must be a .tim/.btim file, so if

                  REM you have, for example, a .cbc and a .tim, do the OpenFile on the

                  REM .cbc and the Compare on the .tim; doing it in the other order

                  REM will fail. If neither of the files is a .tim file, you need to

                  REM convert one of them to a .tim/.btim file first.

                  %syncad% -p%product% --eval-perl-string twf::SetFilterFile(undef);

                  twf::OpenFile(qw(%referencefile%));

                  twf::SetFilterFile(qw(%filterfile%));twf::CompareFile(qw(%basename%.btim));
