Finally we are building the fpga and can view the ila. we are getting out of reset, but we are stuck at PCM = 10b8.

Dang. Looks like the reset button on the arty a7 is actually resetn. I wish they'd named it that way.

Yay! We now have a functional ila and the uart connection on the pc side works. However the CPU is stuck in reset. Not really sure what's going on there.

OMG. the ddr3 has it's own mmcm (pll) which had incorreclty specified the input clock period as 3000 ps rather than 6000 ps so the pll was running at twice the speed. I speed the whole weekend on this. :(

Found and fixed the major architecture issue with the mig 7 used in the arty a7 board.
...
mig 7 is completely different from the ddr4 mig in that the internal pll does not general the required clocks. An external mmcm is required to general two inputs clocks and the required user clock.

Realized we need a separate mmcm when using the mig 7 for ddr3 rather than the ddr4 mig. Go figure.
