Abstract

In a particular processor design an entire logic chip was dedicated to generating, checking and distributing multiple copies of a set of clocks. Each of these sets of clocks then required only minimal repowering on the final logic chip. As VLSI designs have increased the number of circuits and latches placed on a single logic chip, and as machine cycle times become faster, performance demands the distribution of very precise free running oscillators to be used for generating clocks on the final logic chip. This on chip generation will enhance the base distribution system and allow for optimal repowering of the generated clocks. The integral nature of the free running oscillators in the clocking scheme requires that a check be performed to ensure that these oscillators are being received on the chip.
