Hi.

I'm trying to implement to scan and clock gating insertion.
But if I use insertion correctly, I need to know the minimum_bitwidth. But I wondering How I know the minimum_bitwidth?
 

The minimum_bitwidth is a parameter for the clock gating insertion, right?
So it's the criteria to indicate to the tool when the <minimum_bitwidth> of flop-vector need a individual gated clock.
 

Thanks, yes. the minimum_bitwidth is a parameter for the clock gating.
But actually, I wondering about how do you know the number of minimum bitwidth.
 

it is rely dependant how many gated clock you want, the trade-off power/are.
