Explanation of Static Timing Analysis

[vreddy]

can anyone explain in brief abt STA??
y it is said as static y not dynamic timing analysis??

STA consists of??

setup & hold time violations fixing them other than this..i wanna explanation.....

thanks in advance

STA

It is said as static because the timing information is obtain through calculation, not by simulation
STA analysis the delay of all paths register to register, input to register, register to output and check if there is a violation
if the delay of one path is too large, there will be setup violation. the target register will sample the old value.
if the delay of one path is too small, there will be hold time violation. the target register will sample the next value.
Both those two situation will cause error.

Lots of links already there in this forum. Check this one :

Re: STA

get some good traning on STA ,

here its the link, go and regsiter , and login and enter into world of sta.

enjoy guys,

Re: STA

The STA is effective in one clock domain.
When between two clock domain, we should use dynamic analysis(e.g simulation)
to test timing issue.

STA

STA = Static Timing analysis in which there will be no dynamic simulations, rather delays of all paths will be calculated and compared with STA. In dynamic simulation not all paths are excercied, but here it is.
