Compile-Time Options
+acc or +acc+1
Enables all capabilities except breakpoints and delay
annotation.
+acc+2
Above, plus breakpoints
+acc+3
Above, plus module path delay annotation
+acc+4
Above, plus gate delay annotation
+applylearn+filename
Recompiles your design to enable only the ACC capabilities that
you needed for the debugging operations you did, such as
applying breakpoints to signals or stepping through the code in
certain parts of your design, during a previous simulation of the
design. ACC capabilities enable debugging operations but slow
down your simulation so you only want to apply them where you
need them.
You record where you last used them, in a previous simulation,
with the +vcs+learn+pli runtime option. This option records
where you used ACC capabilities in a file named pli_learn.tab. If
you do not change the file’s name or location, you can omit
+filename from the +applylearn compile-time option.
Options for Finding Race Conditions
+race
Specifies that VCS generate a report of all the race conditions in
the design and write this report in the race.out file during
simulation. See “The Dynamic Race Detection Tool” on page 11-2.
