OpenLane quit at synthesis stage but no apparent error

[heliboy2003]

Dear community,

I am pretty new to OpenLane, just started to try it out for only few days. I've successfully run the 'test' and one of my own design (very small) and able to generate GDS. But when I tried a larger design, OpenLane stop at Sythesis stage (Step 1) with no apparent error. The following is the message OpenLane generated in console

I've looked at the runs folder, found no meaningful message telling me what is wrong. So what I should do to resolve this situation?

Thanks

After several attempts, the situation is not solved. I submit an issue and close this.

has anyone solved this? I am getting the same error when trying to run my own design. it seems to also have "-errorcode NONE" and no matter what i try, there is no way to move past the ABC error.
