Hi TCWORLD,

I haven't used the Modular-SGDMA controller, so cannot comment on what you are seeing, however, I can recommend that you create a Qsys system with this component and an Avalon-MM BFM, and then create a testbench that contains exactly the transactions you are debugging, so you can reproduce this "error". At that point you can submit a Service Request to Altera directly, or if you post a zip file with a complete simulation here, someone familiar with the IP core may take a look at the problem.

If you have never used the BFM before, I've posted examples, eg., go to post# 25 in this thread
