Scan chain detachment

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

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... ;-)
