Compile-Time Options
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.
-negdelay
Enables the use of negative values in IOPATH and
INTERCONNECT entries in SDF files.
+oldsdf
Disables compiling the SDF file. Use this option if you cannot meet
the conditions for compiling SDF files. See “Limitations on
Compiling the SDF File” on page 13-5.
+sdf_nocheck_celltype
For a module instance to which an SDF file backannotates delay
data, disables comparing the module identifier in the source code
with the CELLTYPE entry in the SDF file. See “Disabling
CELLTYPE Checking in SDF Files” on page 13-15.
+typdelays
Specifies using the typical 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.
+vcs+mipdexpand
This option is used when backannotating SDF delay values from
an ASCII text SDF file at runtime, as specified by the +oldsdf
compile-time option, which disables compiling the SDF file during
compilation. If the SDF file contains PORT entries for the
individual bits of a port, using this option enables VCS to
backannotate these PORT entry delay values. Similarly, using this
compile-time option enables a PLI application to pass delay
values to individual bits of a port.
