Abstract

This paper describes implementation of a VLSI microproces sor, the TX1, and especially focuses on the design method, which meets the requirements of short design time with reasonable chip size. A one-phase clock system, which is a better solution for high-speed operation but requires careful design for evading the skew problem, is discussed. Design for testability embedded in the chip is also described. The TX1 is fabricated with a 1.0-μm two-laver metal CMOS process. The chip contains 450K transistors in a 10.89× 10.27-mm2 die.
