Quartus-II synthesis/compile errors for Arria V device

Hi Shuo:

I'm glad your making progress with support. And you did the correct thing by having your local Altera Rep/Distributor also working on the issue.. They tend to have a more direct link to higher level factory support.

I discussed this with one of my co-workers and he suggested it may be a mapping issue with Quartus and the Arria V device.

You may want to target a Stratix IV device (If you can easily) that is of similar size and see if the gate level error still exists.

I know this is a time consuming task, but if you are on hold it would at least give you some additional incite into the problem. If you can get quartus to do it on a small test case that is probably the most helpful for everyone involved.

(support and us). If we can reproduce the issue, with quartus, that gives more weight to the support issue.
