Compile-Time Options
Options for Compiling an SDF File
+allmtm
Specifies compiling separate files for minimum, typical, and
maximum delays when there are min:typ:max delay triplets in SDF
files. If you use this option, you can use the +mindelays,
+typdelays, or +maxdelays options at runtime to specify
which compiled SDF file VCS uses. Do not use this option with
the +maxdelays, +mindelays, or +typdelays compile-time
options. See “Specifying Min:Typ:Max Delays at Runtime” on
page 13-38.
+csdf+precompile
Precompiles your SDF file into a format that VCS can parse when
it compiles your Verilog code. See “Precompiling an SDF File” on
page 13-7.
+csdf+precomp+dir+directory
Specifies the directory path where you want VCS to write the
precompiled SDF file. See “Specifying an Alternative Name and
Location” on page 13-8.
+csdf+precomp+ext+ext
Specifies an alternative to the "_c" character string addition to the
file name extension of the precompiled SDF file. See “Specifying
an Alternative Name and Location” on page 13-8.
+maxdelays
Specifies using the maximum timing delays in min:typ:max delay
triplets when compiling the SDF file. See “Min:Typ:Max Delays”
on page 13-37. The mtm_spec argument to the $sdf_annotate
system task overrides this option. See “The $sdf_annotate
System Task” on page 13-3.
+mindelays
Specifies using the minimum timing delays in min:typ:max delay
