quartus_map.exe Exception: Access Violation

Someone else had the very same error messages for a problem that was fixed in version 7.1. It's possible that derguteweka has a different problem causing these same messages, but most likely version 7.1 fixed it.

It looks like derguteweka is going to have to choose between problems specific to 6.1 and problems that are new in 7.1. I recommend using 7.1 SP1, working through any problems with that, rather than dealing with old problems or keeping a design in the old SOPC Builder version for a long time.

If the 7.1 problems in the http://www.alteraforum.com/forum/showthread.php?t=664 thread could have been caused by starting an SOPC Builder design in 6.1 and then upgrading to 7.1, then it might be worth the trouble to re-create the SOPC Builder system from scratch in 7.1 SP1 even though derguteweka had trouble with the first 7.1 attempt. Using 7.1 SP1 means you won't have to deal with any bugs like this fatal error that are supposed to be fixed already. You will still have to deal with any new 7.1 bugs that weren't fixed in SP1--the patch 0.20 mentioned in the other thread might still be needed if the design has a tri-state bridge. But using 7.1 SP1 also means that your design will be easier to maintain than it would be if you kept it in 6.1, which is before the major SOPC Builder redesign that was first released in 7.1. And the redesign in 7.1 provides major benefits for some designs.

If trying 7.1 SP1 again, check the version 7.1 (not 7.1 SP1) release notes for possible issues that I suspect are related to the SOPC Builder redesign in 7.1. The release notes have an "SOPC Builder Issues" section. (The release notes are at http://www.altera.com/literature/lit-qts.jsp.)

I suggested re-creating the SOPC Builder system from scratch if the 7.1 problems could have been caused by changing Quartus versions for a system created in 6.1, but you normally should not have to re-create the system. There is, however, something you should do one time when you first open the system in 7.1. I didn't find official documentation for that, but there is some mention of it at http://www.alteraforum.com/forum/showthread.php?p=2204#post2204.
