From: [ Synopsys Pulled The Olde Switcheroo! ]
The Vital source files in the IEEE/src library are not the ones used to
generate the .sim files in the IEEE/lib directory. Synopsys R&D has
optimized the Vital library packages for simulation, and that's what
they use to generate the .sim files on the CD. (They also redefine
some of the Vital procedures.)
I followed the SolvNet suggestion to re-analyze Vital_Timing and
Vital_Primitives, and then I couldn't analyze a Vital library from
my semiconductor company without errors. I traced this down to the
difference in the Vital files. I got the correct source files from the
Synopsys hotline and was OK. This should all be fixed in about 5
months or so. (Synopsys R&D knew what they were doing, but the AE I was
working with was quite surprised at the switcheroo.)
No name, no company please.
