Optimization techniques

[tachyons]

Hi All,

1) What are the different techniques used by optimization tool to fix setup/hold violations ?
2) Does this applicable to all preCTS/postCTS/postRoute optimizations ? If not, how do the optimization techniques differ in each stage?

Hi tachyons,

Please refer https://www.edaboard.com/threads/178482/ & https://www.edaboard.com/threads/84656/ for setup and hold fixing

Hope you find it useful...

PS: lot of questions in one day..hmm

Setup ..decrease data path delay...hold increase data path delay...setup..introduce useful skew..data path optimization can be by buffering, changing drive strength, multi vt techniques etc..
