A computer-based method and system is disclosed that automates the design and layout of digital multiplier circuits. The preferred method utilizes an automatic design generator having a user interface which receives design requirements for a digital multiplier circuit design. A digital multiplier design generator receives the design requirements for the digital multiplier and retrieves relevant component implementations from a component library. Stored digital multiplier benchmarks are then retrieved from a benchmark memory and applied to corresponding digital multipliers to determine which of the various implementations optimally satisfies the user design requirements. Once the optimal digital multiplier implementation is selected, the digital multiplier design generator produces a logic design including a netlist and a physical design including design directives which are then used to place and route the digital multiplier as a finished layout. Once the layout is completed, the finished layout simulation results are then evaluated against the benchmark results to determine if the actual implementation meets the user requirements. If the user requirements are not met by the actual implementation, then information for generating another implementation is fed back to the digital multiplier design generator.
