Hello All,
We can do multiple capture if the clocks are independent.
To cover the clock domain crossing faults, we can do :
e.g. 2 consecutive scan stitched flops.
1st flop ff1 : clk1 and
2nd flop ff2 : clk2,
there is some combo logic between ff1 and ff2.
In such case,
1. Shift-in all chains
2. Pulse clk1
3. Pulse clk2
4. Shift-out all chains.
By doing sequentially pulse of capture clock we can cover the faults between clk1 and clk2 domain crossing.
Above procedure is not for all the patterns but only to cover clock domain crossing faults.
Hope it solve your question.
