vpd format

Can anybody please explain me the difference between VCD file VPD file in detail. which one is better and which one is used where?
Thanks in advance.
 

vpd file

As per my knowledge, the VCD file is the IEEE standered defined format for the waveform dumping, so it will be supported in all the simulators and waveform viewers. While VPD is the Synopsys standard for the waveform data base, so it will be supported by only Synopsys tools. VPD size will be lesser than the VCD file so, better to use VPD if you have Synopsys tools(e.g.VCS)

Hope this Helps.

convert vpd to vcd

I think Novas FSDB is the best format.
If you have debussy, use it.

VCS contains only the signal activity while VPD/SHM/WLF/FSDB - all binary formats from various vendors contain lot more debug information (such as drivers etc.). It is best to use the binary format and if needed convert it to VCS via:

vpd2vcd
fsdb2vcd
shm2vcd
wlf2vcd

Commands.

vpd synopsys

If u want to generate a TDL and run QC flow, U must use VCD.
 

vpd vcd

can anybody tell whats the full definition of VPD?
for example VCD-> its value change dump
 

vpd2vcd

Can you make sure the VCS has wlf2vxx?

I can not find it under the directory of my VCS v2006.06-SP2-2
 

vpd waveform

Hi appu 5

full def VPD - VCD plus (valus change dump plus)
 

vpd dump

wlf2vcd is in modelsim. As wlf file is generated by the modelsim. VCS won't be having it as, Synopsys has nothing to do with the wlf file which is proprietary to Modelsim.
