Primetime start point and end point

ASIC_ · Feb 18, 2013

I always getting the invalid start point and invalid end point in my prime time timing report.
It is an input pin of an module, not sure why prime time can`t treat them as valid point.
anyone knows how to let prime time treat it as valid point? I am really new to this stuff

thanks

To my understanding:
--- Start Point ---
1): Top module inputs (not sub module inputs)
2): The clock pin of a DFF/Latch
3): clock network (use the clock name when you define a clock)
--- End Point ---
1): Top module outputs (not sub module outputs)
2): The D/Enable/SYNC reset pin of a DFF/Latch. Maybe also include the clock pin of a DFF (please try it).
3): clock network (use the clock name when you define a clock)
