There are slew violation in the design. Increase the slew margin parameter and try it. Default value

Copy code

set ::env(PL_RESIZER_MAX_SLEW_MARGIN) {20}

@User There are setup and hold violations in your design.

Copy code

===========================================================================
 report_worst_slack -max (Setup)
============================================================================
worst slack -6.55

===========================================================================
 report_worst_slack -min (Hold)
============================================================================
worst slack -2.02
worst_slack_end

This is the reason for flow fail. check

26-parasitics_sta.log

. As per flow configuration post routing no min/max violation. Otherwise flow will fail
