General Description: This solution is an overview of using M1 constraints with FPGA Express as the top-level design tool. Constraints that FPGA Express can directly apply will be documented. Information on how to reference instance names in XNF files from FPGA Express will be documented; when constraints are needed that FPGA Express cannot apply, a UCF file referencing instance names in the XNF file will be made. Similarly, information on how to reference the instances inside LogiBLOX RAM/ROM modules will also be provided for creating UCF constraints.
