cascade buffers on DontTouch nets during CTS

Rajesh Vembu
Rajesh Vembu over 14 years ago

CTS engine doesn't seem to honor DontTouch nets, as some CASCADE buffers are added on the DontTouch nets.

Can someone share some thoughts on

1. why CTS engine doesn't honor DontTouch nets?

2. is there a way to instruct the tool to avoid insertion of CASCADE buffers on DontTouch nets?

 

Regards

Rajesh
