Hi
We are at the process of simulating a gate level post-route verilog netlist using ncsim. We see a few INTERCONNECT information in the sdf file that shows negative delay.
While elaborating we get the following warning code (SDFNDP):
An attempt was made to annotate a negative delay value or pulse limit to a specify path or interconnect delay. The value will be set to zero.
We are aware that vcs has a switch -negdelay which annotates the negative delays of sdf file.
Does anyone know what is the switch for ncelab ?
