vcs sdf

Hi everyone,
I am using synopsys vcs to do post simulation, and after using the $sdf_annotate as well as .sdf which was generated by primetime, I have the following problems,
I can not find any useful information from the vcs manual, does anyone have suggestions, thanks very much,

vcs sdf annotation

check the hierarchy you are using while calling $sdf_annotate in the simulation env, and open you sdf file and see from which hierarchy the prime time created the sdf file.

vcs sdf error

Thanks very much,
I suspect it maybe the verilog library problem,
Do you know how to set up library in VCS,
Thanks,

vcs simulation with sdf

when u compile, add -v library_path/library_name

sdfverbose vcs

Thanks very much,
You are right, but the problem is how to get the suitablt verilog library.
It seems we can not write it by Synopsys software.
Any suggestions?

Are you still seeing the issue?
Try using newer verions of vcs.
