Doubt in VCD format Report this article as Inappropriate to us !!!Login to Reply

Hi All,

I am a test engineer analysing VCD file formats.  Please help me to clear my doubt.
When we want to generate a VCD file we will call the system tasks
"$dumpall, $dumpon, $dumpoff, $dumpvars" etc., inside a verilog code.
But these tasks are again used in the generated VCD file like :
"$dumpall 1*@  x*#  0*$  bx (k $end".  I do not know what is the
reason to use "$dumpall, $dumpon, $dumpoff, $dumpvars" kind of
commands in the generated VCD file. Simply stating what is the need
for Simulation keywords inside a generated VCD file. (Are they used to
cross verify the dumped waveforms).
Thank you in advance.

Since you work with VCD you may want to look on:Extracting data from a VCD waveform format at http://bknpk.no-ip.biz/incremental_backup/misc_scripts.html


In general there are quite a few intersting issue for digital desginers at http://bknpk.no-ip.biz
