5.1i DATA2BRAM - The "_bd.bmm" file generated by BitGen is incorrect

Description

General Description:

When I place BRAMs in the R0C0/X0Y0 location, BitGen writes the "<file>_bd.bmm" file incorrectly. As a result, DATA2BRAM cannot properly update the BRAM contents.

Solution

This problem is fixed in the latest 5.1i Service Pack, available at:

http://support.xilinx.com/support/techsup/sw_updates

The first service pack containing the fix is 5.1i Service Pack 5.1i.

Alternately, to avoid this problem, add the following constraint to your UCF file:

For Virtex-II/Virtex-II Pro devices:

CONFIG PROHIBIT = RAMB16_X0Y0;

For all other families:

CONFIG PROHIBIT = RAMB4_R0C0;
