Is there a problem when simulation ALTDQ_DQS2 megafunctions generate by the Quartus II version 12.0? - Is there a problem when simulation ALTDQ_DQS2 megafunctions generate by the Quartus II version 12.0? Description Yes, there is a problem when simulation ALTDQ_DQS2 megafunctions generate by the Quartus II version 12.0. When ALTDQ_DQS2 in output-only mode, Full-Rate, with no dynamic config or output phase alignment blocks, the core left the output strobe enable dangling. Resolution Add the following code : assign fr_os_oe = 1\'b0; to ALTDQ_DQS2 megafunctions source file as a workaround.
