undefined system task call to $vcdpluson

Hi folks

I'm trying to compile my files on VCS, and I'm getting these 2 errors:

#######################################
Error-[UST] Undefined system task
Undefined System Task call to '$recordfile'
"
/path_to_my_file/my_file.v
", 214

Error-[UST] Undefined system task
Undefined System Task call to '$recordvars'
"
/path_to_my_file/my_file.v
", 215
#######################################


What should I do to avoid these errors ?
 

vcs debug_pp

According to those Error messages, 2 system tasks $recordfile and $recordvars are undefined.

Please define these 2 system tasks in Verilog then the problem will be solved.

The 2 mentioned system tasks { $recordfile and $recordvars } are already supported by synopsys. Please read this link :

https://solvnet.synopsys.com/dow_retrieve/A-2007.12/espcv/espcv_5.html#CACJECDH

They exist under SST2 Dump File Support :
$recordfile
$recordvars
 

system call vcdpluson

According to the above link, these 2 system tasks are supported in product ESP.

Do they also supported in VCS ?

Thanks in advance.

$recordvars is part of Signalscan which was a separate tool, now part of Cadence. You need to set the correct TAB file for the same. WHy don't you just use the VPD format that's native in VCS? Much easier to use:

Code: 
initial
 $vcdpluson;

vcs -debug_pp file.v

In fact, I'm verifying an external IP using the IP's supplier own testbenches/scripts .. these testbenches/scripts were originally written for use with ModelSim .. currently I want to port the whole simulation environment to VCS as it's my company's default simulator ..

How can I use the proper TAB file ?
 

undefined system task fsdbdumpfile

Please use the "-P" option to specify the necessary tab file as following:
> vcs -P <filename.tab>
 

vcs error ust undefined system call
