hi, everyone. I try to make nangate45/swerv. I defined parameters like this on config.mk export CAP_MARGIN = 60 export SLEW_MARGIN = 40 export PL_RESIZER_HOLD_MAX_BUFFER_PERCENT = 70 export PL_RESIZER_HOLD_SLACK_MARGIN = 0.8 export GLB_RESIZER_HOLD_MAX_BUFFER_PERCENT = 70 export GLB_RESIZER_HOLD_SLACK_MARGIN = 0.8 but there are hold time violation on final result. How can I fix hold violation? Thanks for any help! #openroad

With default variables what is hold violation count?

@Vijayan Krishnan default hold violation count is 224, and with default variables there are slew and cap violations.

Can you check after placement and CTS stage what's the hold violation count?

@Vijayan Krishnan Yes! Left is defalt version and Right is modified version…

CTS stage hold violation count is 0... After routing hold count increase... Can you raise GitHub issue with test case for placement stage?
