Well, I've seen that - but how hard would it be to use, say, a
modified Spartan 3A softcore MIG on a Spartan 6? Anyone attempted that?

There isn't a soft-core MIG for Spartan-6.

Hi,
Is there a way to hack the MPMC into not using the MCB (but the
softcore MIG) on Spartan-6? The MPMC datasheet says no, but since the
MIG source code is mostly behavioral (iirc), maybe there is a way
around this.
I have a board with DDR SDRAM and a pinout that is not compatible with
the MCB, and my custom softcore platform (that is not using the MCB)
randomly crashes when running complex software (Linux systems etc.).
I'm suspecting a DRAM problem. It is stable on Virtex-4, tested on the
ML401 board. I would like to test my custom board with Microblaze in
order to put potential PCB or signal integrity problems out of the
equation.
Thanks
