9.2i EDK, MPMC v3.00a - Timing failures in PLB and SDMA PIMs when using 2:1 memory to PLB ratio


When using the PLB and SDMA PIMs with a 1:2 clock ratio to the memory clock, timing failures occur at a faster required memory clock rate. My PIM should be running at half the memory rate. How do I resolve this issue?


The failing paths that occur in the PLB and SDMA PIMs running at half rate are caused by multicycle logic used to support 1:1 clocking. This issue will be fixed in a new version of the MPMC and PIMs, to be delivered in the EDK 9.2i Service Pack 2 tools.
