crosstalk in common clock path

[edagops]

Hi,
When the crosstalk (delta delay)occurs in the common clock path of launch and capture flop?
What will be the impact in timing ? i.e setup or hold violation or no violation ?


Tnx.

Hi,

No New setup or Hold violation should occur. If path is timing clean.

Hi Nantha,

When a crosstalk delta delay adds up on common clock path of launch and capture flops....clock path at capture end gets delayed by same amount as launch path. So, it will not create any new violation.
