How to set NoTimingCheck on a single instance in NC-Verilog

[bgpradeep]

Hi,

I would like to know how i can set No Timing check on a specific instance and to ignore only the recovery time check or only hold time check on this instance in NC-Verilog?

Thanks..

If you use SDF file you can change ignored values to zeroes.

Thanks for the reply..this method will work but i wanted to find a different way so that i don't have to modify the SDFfile everytime a new one is created...

you can add the "PATH instance hierarichy -tchek " in a file , then using notiming check option to read this file!

If you use Design Compiler you can use "set_annotated_delay" command in your script to generate zero delays in automatic mode.
