attributes not propagating to split blockmem

I have an array that Quartus correctly infers as memory. The data is wider than any blockmem so it gets split into several parallel, as expected.

When I try to set attribute (ramstyle=NO_RW_CHECK) to the array, it is not passed down to the split signal. Is this a bug, or do I have to explicitly tell the Quartus to do this?

    What are you expecting it to do? do some memorys now have different read before write behaviours? It should pass it to all memories, if its not, I suggest raising a mysupport bug request.

    How are you checking that it's getting passed or not? I've seen this work before, but don't have a ready example. As Tricky says, a mysupport case might be in order.
