（笔记）静态时序分析

three steps of STA:

1.Design is broken down into sets of timing paths

2.Delay of each path is calculated

3.Path delays are checked to see if timing constraints have been met

 

There are 4 types of PrimeTime paths:

Input port to data pin of flip-flop (Path 1)
Clock pin of flip-flop to data pin of flip-flop (Path 2)
Clock pin of flip-flop to output port (Path 3)
Input port to output port (Path 4)
