Product Family: Software

Product Part: VCS
Problem Title:
VCS: Error: undefined system task or function $sdf_annotate
Problem Description:
Urgency: Standard
General Description:
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
Solution 1:
NGD2VER will wirte the following line to the timing simulation netlist:
initial $sdf_annotate("design.sdf");
$sdf_annotate is not a valid VCS system call.
Use +compsdf VCS option to read in the SDF timing information.
Please see (Xilinx Solution 6349) on how to use the +compsdf
option.
