Hi! Does anybody know why all opensta report files in reports/synthesis are empty? All STA results are available only in logs/synthesis dir.

They’re all empty? Including reports/synthesis/3-opensta.min_max.rpt?
Maybe synthesis didn’t pass? is there a .v in results/synthesis

@Eric Smith Yes, they are all empty! At all 4 runs during flow. Synthesis passed. All verilogs are generated. And there are STA logs in logs dir.

@Eugene Stolbikov I presume your WNS and TNS was 0? If I am not wrong the files provide the details when you have negative slack. Try with higher frequencies till you see a negative slack and check if the files are still empty

@Eugene Stolbikov Interesting. Not sure how there can be a pass but no min and max. Maybe check logs/synthesis/17-opensta_post_resizer_timing for warnings or errors?
