Design method of a logic circuit

摘要

Even if only logic circuits described in HDL are distributed over a network, if the logic synthesis ability is insufficient, the overall design capability cannot be enhanced; e.g., a sufficient performance of a gate level logic circuit cannot be attained, or it takes a long time to complete logic synthesis. Considering design skills for logic synthesis are considered as property, the invention enables distribution of design skills between a plurality of design sites over a network interconnecting computers. Charges for a design skill are set for the rates of improvement to the performance of the logic circuit that was refined by the design skill. Desired circuit performance can be attained in a shorter period by shortening the design phases in which an RTL logic circuit is supplied as input and by logic synthesis thereon, a gate level logic circuit is output.
