Abstract

An effective design method for VLSI-based microprocessors is proposed. According to the method, the chip is divided into three categories; control logics, datapaths and macrocells at the very early stage. The control logics are automatically designed by a logic synthesis and an automatic placement & routing. For the datapaths and the macrocells, logic and layout are designed manually. By combining the design method with "design-pipelining", a 32-bit microprocessor including 460K transistors was designed in a year without sacrificing the chip size and the performance. An impact on design effort is also discussed.
