Validation

The validation of design is basically the post extraction PRIMETIME analysis of the design.  After APR, we have the timing report file design.dspf.  Using this file we can do the post extraction PRIMETIME analysis.  

First we need to download the following scripts.

        preapr.script
        postapr.script

Let us save them in the directory where we do the APR. It is directory  ~/simpleAPR/APR

Now go to this directory

        cd ~/simpleAPR/APR
        cp design.v design
        cp ../../standardcell/.synopsis_pt.setup .

Next we need to change some lines in preapr.script and postapr.script

For the preapr.script, we need to use the name of our design module.

We do the same thing for postapr.script

Now, we can run the PRIMETIME.  Type:

        pt_shell

We are in the pt_shell. Type:

        source preapr.script

We can see the following report:

then type 

        source postapr.script

We can see the following report

We can see that post extraction timing report gives a longer time than the pre-extraction one.
