delete_timing_netlist
Usage
delete_timing_netlist
Options
None
Description
Use this command to delete a timing netlist previously created using create_timing_netlist. This should be
done at the end of a script or before calling create_timing_netlist again using different options or after
recompiling the design.
Use the set_operating_conditions command instead of delete_timing_netlist and create_timing_netlist to
change timing models. This avoids the cost of deleting and re-creating the timing netlist, and also
preserves current timing assignments.
