In general, I would agree with the concept of maintaining a Wiki page for workarounds however, I would like to ask a fundamental question to anyone that has tried the 11.0 tools and/or migrated a design to the new Qsys environment:
Do you believe this 11.0 tool release represents a reasonably well-engineered product?
And a follow up question: Will you continue to use the 11.0 tools or will you revert to a previous release and wait for the next one?
My impression is that Altera has committed themselves to two annual tool releases (one in spring and one in the fall) and the schedule has become the most important factor of consideration regradless of how well the tools work when the release date rolls around. I do not see a reasonable engineering explanation given of how the Qsys system differs from the SOPC implementation so that as an engineer I can understand why they did what they did and understand how to tailor those changes to my project.
The impression I get is that if the tools aren't quite ready to go, then Altera will let the users be the guinea pigs and provide the feedback to clean up the tools for the next release. And that's all well and good, but those of us that pay the yearly maintenance fee should not be doing the testing that Altera should be doing as part of the responsibility that comes along with selling a product.
