where is the interconnect delay after P&R in encounter?

After P&R in encounter, I saved the timing reports. However, in  postRoute_in2out.tarpt, I only see the delay of every gate in each path.

There is detailed RC information, the interconnect delay should be calculated during timing analysis, where is it?

What engine is called by encounter for timing analysis after P&R?

     If you want to see separate lines for the net delays, use report_timing -net etc...

    The net delay is not output by default because it usually shows up as 0.00 (the delay is smaller than the default precision). However, if you have a long detour route, or some other issue, you may see net delay. I'm guessing you're trying to debug something like this.

     The engine used depends on what you have set with setDelayCalMode -engine. You can use getDelayCalMode to find out what is currently being used.
