FeatureExtract different from FeatureDownload from N28
When I used the code in the feature_extraction folder to extract features, I found that the npy features generated by the script were inconsistent with the routability_features_decompressed features downloaded from googledrive. For example, I used 10129-zero-riscy-b-3-c5-u0.9-m1- The two defs corresponding to the p6-f0 design (place stage and route stage) and circuitnet.lef generate cell_density feat. They are inconsistent with the downloaded cell_density features and there are a lot of strange noises. The two defs I used can be found in the compressed package. To obtain, the code uses the feature extraction in the repo and only modifies the path. place&route-DEF.zip
We have identified the issue and will address it by uploading new DEF files in a few days.
