quartus_asm: Error in merging. Locked bit differs

Altera_Forum · ‎11-11-2015

I have a Stratix 4 project based on several iterations of the incremental compilation design flow. Each stage exports a QXP file and the final project consists of a single imported QXP file and an SDC file. When running the assembler, I observe the following error:

Its a crash - you'll need to report it to Altera via mysupport

Altera_Forum · ‎11-12-2015

Thanks for the reply. I figured as much and opened a ticket with Altera support. I probably should have mentioned that in the original post...

I was more or less wondering if anyone had seen this before or knew of a workaround. Again, I probably should have mentioned that...

You are right, Quartus II crash generally cannot be fixed by user. You can try to request a patch from Altera to get around it.

I received feedback from Altera support for this issue. Adding the attached quartus.ini file to my project resolved the issue.
