The Spartan-6 MCB design requires thatspecific board layout rules be followed in order for the design to behave correctly in hardware. The following Answer Records provide detailed information on the board layout requirements. Information can also be found in the"Designing with the MCB">"PCB Layout Considerations" section ofthe Spartan-6 FPGA Memory Controller User Guide(UG388):

• (Xilinx Answer 40778) Termination and I/O Standard Guidelines
• (Xilinx Answer 40771) Trace Matching Guidelines
• (Xilinx Answer 40868) Simultaneously Switching Noise (SSN) Guidelines

On top of following these rules, it is strongly recommended users run SI Simulations using IBIS Models to verify signal integrity:

• (Xilinx Answer 34708) IBIS Simulation

If after verifying these rules have been followed and errors are still seen in hardware, please refer back to the main Hardware section of this Design Assistant to look into Pin-out Requirements and Hardware Debug.

• (Xilinx Answer 37502) Hardware Analysis
