ABSTRACT:
A memory controller design tool retrieves parameter ranges supported by a memory controller, and identifies troublesome parameter value combinations. The memory controller design tool suggests to 1) add logic to the memory controller to resolve the conflict, 2) incorporate a constraint that reduces/eliminates command collisions, data conflicts, and/or the need to check particular timing parameters, or 3) a combination of both. The memory controller design tool may work in conjunction with a memory controller designer to define and use the constraints.
