Hi, you may check out develop branch. The problem comes from higher python version. We have fixed it.

https://github.com/limbo018/DREAMPlace/blob/8e9f599084e0658f81a1e29706594e55a8060a82/dreamplace/PlaceDB.py#L576

Thanks for your help. i already change to dev branch. but the problem still exists.

I think the Exception is the critical problem instead of the warnning

[limbo018]

It looks like you have changed the code? (you wrap it in the subprocess) Does the original version of code run?

[imcamino]

Yep.i just wrap it in a Entry script。 Actually It works for ISPD case，but fail to run other case come from open source。

If you can share the LEF/DEF files of your case, I can help take a look. There might some problem when reading the design.

[imcamino]

test_case.zip There is one of my case.

Ok, I appreciate your time.

Hi, I just took a look at your DEF file. The COMPONENTS section is missing. You can compare the DEF files with other benchmarks like ISPD 2015 and will find the differences.

Thanks for your reply. i will write the def out with unplaced stdcell & try.
