To optimize the scan-path (usually the hold violations in scan mode), we either do scan-reordering or CTS in scan-mode in MCMM flow. Could anybody explain which way is more beneficial and why.
In scan-reordering , during placement it reduce the scan-chain length to avoid the congetion but during CTS stage it checks the hold violations in scan-path and fixes it by inserting the buffer , so thiming would be met in both functional and scan mode. Then how it is different than performing CTS in scan-mode in MCMM. I know MCMM is for multi-scenario/modes and gives much better results than single scenario flow, But I want to know how differently it does CTS and fix the timing.
Thanks.
