The first 64 b S/390 microprocessor implemented in a 0.18 /spl mu/m, 7-level copper interconnect bulk CMOS process, runs operating system and applications at 1.1 GHz. The frequency is achieved with interconnect width and repeater optimization, selective use of low-Vt devices, tapered library gates, and improved synthesis and circuit tuning algorithms.
