Issue in getting net metrics

[vikrg23]

I am trying to get net metrics like resistance, capacitance and coupling cap in OpenROAD. But the APIs are returning 0.0 for all the nets in my design. I am using post-route db for this. Please let me know if there is a solution for this issue.

I have attached a testcase for this issue. After extracting the file contents, go into the testcase directory and source the runme.tcl file in OpenROAD.

Your test case consist of only a runme.tcl and no actual files.

Sorry my bad @maliberty , attaching proper files.

Hi @maliberty , any fixes for this issue?

[maliberty]

read_spef reads the parasitics directly into sta and not into odb. Trying to query odb fails as nothing is stored there.

Hi @maliberty , so what is the correct way to get the parasitic from a design?
