detach scan chain

Hi,

I have a design in which I find there are several scan chains existing. Thus, there is no one single scan chain in the design.

Is there a way that I can detach these several existing scan chains.

Is it possible with DFT compiler.

Thx

Nikhil

yep ,u could report the scan chain with -existing command
 

What is it you mean by 'detach'? You want to unstitch the scan chains and redo them in another way? If so, I believe DFT Compiler will do that anyway, unless you specify them and put dont_touch on them. The tool is quite rude that way... ;-)
