in synopsys what is the switching activity file

[balavinayagam]

i am not so familiar with the tools of synopsis. what is the switching activity? Is it a measure of dynamic power .

what is this file

thanks to anyone who replies

Hi,
Check out the pdf in the mentioned link. You will get familiar with switching terms.

Switching activity file also known as SAIF in short, is a file that captures the toggling activity of all the circuit nodes in the design. It is similar to the VCD, except that this is normally much smaller in size and hence easy to generate (takes less time) and manage (less disk space). It can be written out during simulation using VCS/NCSIM etc. and is used by Power compiler for dynamic power analysis. You can read in the SAIF file in place of a VCD file.

thanks for the reply.Could u please suggest a good tutorial to learn synopsis DC , primetime etc

thank you

For DC check for design compiler handbook

In normal, you should do the simulation to get the VCD wave file with SDF.
Then you can evaluate the power with these VCD files.
