Altsyncram mixed port width issue

I had same issues with u when use Qsys, mem 2 port, porta 32bits, portb 8bits. (synthesis false).

Error (272006): Cannot use port A width with port B width in altsyncram megafunction

Error (287078): Assertion error: The current megafunction is configured for use with the clear box feature and cannot be used when the clear box feature is disabled

Compared with file generate from IP Catalog, with same config. (systhesis ok). I figured out that issue was

.byteena_a(byteenable)

then I changed it to .byteena_a(4'b1111) // in this case, I use full 4byte for port a

It okayed with me.
