Hi,

How does sequential depth appears in waveform during simulation?
For example, If my design has sequential depth equals to 3(no. of non-scan cells), then how will be the capture clock wave-forms for the stuck-at patterns? Will there be 3 capture pulses in capture window?

I understand ATPG tool will use fast/full sequential ATPG algorithm and provide multiple captures to generate patterns. But do we actually see 3 or more than 1 capture pulses in simulation wave-forms? If not then,why?

Regards,
Shalin
