hi,

When you synthesis your design using cadance buildgates, generates a timming report.
In the report, could some please explain me the meaning of some terms like .

Other End Arrival Time 0.00
- External Delay 1.50
+ Phase Shift 10.00
= Required Time 8.50
- Arrival Time 1.31
= Slack Time 7.19

This is the timming report i got .

In this what do yo means by "REQUIRED TIME", "ARRIVAL TIME", "EXT DELAY","PHASE SHIFT".

I calculate the total time delay by T = PHASE SHIFT - SLACK TIME
and maximun frquency by F = 1 / T.

Pls help me if i am wrong .

Thanks for you help in advance
