Abstract

As the Application-Specific Integrated Circuit(ASIC) technology develops to the trend of high density and modulization, the ASIC device market has been dominated gradually by the more complex Erasable Programmable Logic Devices (EPLDs) and the Field Programmable Gate Array(FPGAs) instead of the ordinally Programmable Logic Devices(PLDs). Meanwhile, the design automation system for such programmable devices has also moved from schematic entry design to high level hardware description language entry design. Usually, the whole design automation process consists of three phrases, the high level hardware description language compiler, the logic synthesis stage and the layout synthesis stage. Though the layout synthesis stage contains placement and routing, for some highly restricted connection architecture devices, placement and routing have to be considered together as a fitting problem. This thesis concentrated on the utilization of the Heuristic methods, which can be described as vertex ordering and global vertices number estimation, on an Architecture-Driven Partitioning fitting algorithm. The test results showed that the heuristic algorithm can beat the comparable algorithm in several fields. These prove the correctness of our heuristic methods and they can be used to guide the future work on the fitting problem of other similar programmable devices.
