This paper presents a design methodology emphasizing early and quick timing closure for high frequency microprocessor designs. This methodology was used to design a Gigahertz class PowerPC microprocessor with 19 million transistors. Characteristics of 'Timing Closure by Design' are 1) logic partitioned on timing boundaries, 2) predictable control structures (PLAs), 3) static interfaces for dynamic circuits, 4) low skew clock distribution, 5) deterministic method of macro placement, 6) simplified timing analysis, and 7) refinement method of chip integration with early timing analysis.
