VCSi
VCSi is offered as an alternate version of VCS. VCS and VCSi are
identical except that VCS is more highly optimized, resulting in greater
speed. VCS and VCSi are guaranteed to provide the exact same
simulation results. VCSi implementation requirements are
summarized as follows:
1. There are separate licenses for VCSi.
2. VCSi is invoked using the vcsi command, instead of the vcs
command.
Note:
Hereafter, all references to VCS in this manual pertain to VCSi as
well.
The +vcsi+lic+vcs compile-time option enables you to run VCSi
with a VCS license when all VCSi licenses are in use, and the
+vcs+lic+vcsi compile-time option enables you to run VCS with
three VCSi licenses.
