Hello, I am trying to implement the USRP2 FPGA HDL using Xilinx ISE 11.1. I have set-up the file structure and the project options per the makefile for U2_rev3. It will synthesize and translate (39 BRAM) but fails map with 44BRAM. The BRAM usage at map failure is:

Any help or ideas would be greatly appreciated.
