General Description:
I receive the following error:
"Error: undefined system task or function $sdf_annotate ./pcim_top_routed.v 4513:
initial $sdf_annotate( "pcim_top_routed.sdf");"
NOTE: Optimal use of SDF ($sdf_annotate) requires a custom PLI table file. This file is specified using the -P switch, eg:
vcs myasic.v -P sdf_myasic.tab
An entry in the "sdf_myasic.tab" file for your design might look like:
$sdf_annotate call=sdf_annotate_call acc+=mp,prx:myasic+
where myasic is the top level module to be annotated. For details on specifying acc capabilites, see Ch4 and Ch5 of the VCS User's Guide.
Errors: 1"
NGD2VER will write the following line to the timing simulation netlist:
initial $sdf_annotate("design.sdf");
$sdf_annotate is not a valid VCS system call.
Use the +compsdf VCS option to read in the SDF timing information. Please see (Xilinx Answer 6349) on how to use the +compsdf option.
