Removing existing set_false_path netlist assignments

[FRoth]

We have a set_clock_groups command, specifying false paths between clocks. Is it possible to remove a set of false paths from this set, fulfilling a given condition? That means, reverting a set_false_path, but only for specific nets in the netlist?

Looking into an older TimeQuest reference, there used to be a reset_path option for set_false_path, which would reset the given path and optionally remove any false path assignments. That is what would like to achieve, but this option produces an error in TimeQuest 18.1. Is there any replacement command to retroactively remove a set of already entered false paths?

Hi,

Could you share the error message and the version that the reset_path is working?

Thanks.

Hello,

There is a SDC parsing error in TimeQuest (Unknown option: -reset_path). Looking into the TQ documentation, the -reset_path option is not supported. The older version I was referring to was from quite a long time ago and I cannot seem to find the reference now. Is there any similar command, which could remove existing false path assignments from a set of nets in netlist?

Thank you

Hi,

Upon checking, there is no command to reset the path. you have to use set_false_path to remove the paths from timing analysis in this case.

Thansk.
