Is ISPD2018/2019 contest benchmark still supported?

[bangqixu]

I am trying to run ISPD2018/2019 contest benchmark with TritonRoute using OpenROAD. From what I can tell from an earlier thread which refers to https://github.com/The-OpenROAD-Project/OpenROAD/blame/master/src/drt/test/ispd18_sample.tcl. When I use a similar script to run for ispd18_test1, it crashed with [ERROR DRT-0229] genGuides_split split_indices is empty on Metal3..

For ispd18_test2, it stopped with [ERROR DRT-0305] Net net35622 of signal type GROUND is not routable by TritonRoute. Move to special nets.

I have not run through all the testcases, but it seems a good amount of them may not go through. Are these benchmark designs still supported by OpenROAD?

It would be great if the contest benchmark and format are still supported. Any help would be very much appreciated!

They are still supported. @osamahammad21 please comment.

You can see the setup

OpenROAD/jenkins/Jenkinsfile.nightly

Line 36 in 5a1818f

ISPD_YEAR.each { ispd_year ->

and it is passing in the CI

Thanks for getting back to me! I would like to confirm whether there are edits made to the testcases inputs?

The testcases from my end were all recently downloaded from ISPD website.

Meanwhile, I can sync and try again.

I got them from you long ago....

Gotcha. I do not recall that I touched the inputs. The goal was to be able to run it out-of-the-box. Let me try with a newer build then. Thanks again!

Hi @bangqixu . As Matt said there is a dedicated Nightly CI that runs the ispd18 and ispd19 testcases, so yes they are still supported and working fine. However, we have a modified version of the ISPD input files on the CI machines. For example the Ground net net35622 is modified to be a signal net on the CI machines. This is because we assume that power nets out of scope for the detailed router as they are usually handled prior in pdngen.

Thanks for the reply! Is there a way to share the modified testcases (or the diff of those modified testcases)?
