A unified single-phase clocking scheme for VLSI systems

Two of the main consequences of advances in VLSI technologies are increased cost of design and wiring. In CMOS synchronous systems, this cost is partly due to tedious synchronization of different clock phases and routing of these clock signals. Here, a single-phase clocking scheme that makes the design very compact and simple is described. It is shown that this scheme is general, simple, and safe. It provides a structure that can contain all components of a digital VLSI system, including static, dynamic, and precharged logic as well as memories and PLAs. Clock and data signals are presented in a clean way that makes VLSI circuits and systems well suited for design compilation.>
