ABSTRACT:
A method and apparatus for clocking latches in a system having both pulse latches and two-phase latches includes a clock generating circuit for generating a local clock signal based on a global clock signal and also includes a pulse generating circuit for generating a pulse signal based on the global clock signal. A clock signal path transfers the local clock signal from the clock generating circuit to both a first portion and a second portion of the two-phase latch. Similarly, a pulse signal path transfers the pulse signal from the pulse generating circuit to the pulse latch. According to one embodiment, the pulse generating circuit and the clock generating circuit have paths of equal delay, thereby causing a rising edge of the local clock signal to occur at the same time as a rising edge of the pulse signal.
