Hi ,
I don't know about WINNT ,but for LINUX / Solaris you can find the PLI files in the installation path . Link your PLI tab files to your simulator .The linking varies with simulator .
Then you can dump using ,
initial
begin
$fsdbdumpfile(file_name);
$fsdbdumpvars(level,instance_path);
end
do you want to watch the waveform using debussy?
this way :
you can dump the VCD file use Modelsim
then use the nWave to open the VCD file
nWave can change the VCD file the fsdb format automatically
