Timing verification of dynamic circuits

A complete set of algorithmic rules is presented for timing verification of domino-style precharge logic circuits. These rules include identification of dynamic nodes in a circuit, generation of timing constraints based on the operating environment of a dynamic gate, and verification of the timing constraints as part of a complete timing verification process. An important part of this approach is propagation of gated-clock pulses which are used extensively in dynamic circuits. The algorithms have been implemented in a new static timing verifier called MTV (Mips Timing Verifier) which is targeted towards verification of custom microprocessor circuits. MTV has been demonstrated to be useful on a number of real-world custom circuits
