METHOD TO REDUCE WIRE-OR GLITCH IN HIGH PERFORMANCE BUS DESIGN TO IMPROVE BUS PERFORMANCE

A system and method of reducing wire-or glitch to improve bus speeds. In a system that supports wire-or functions, the rise time of the wave created by the off-going driver is controlled. The off-going wave is forced to climb gradually such that one propagation delay of the loaded bus later, it is only marginally above a high threshold voltage. The fall time of the wave created by an on-going driver is minimized such that a strong negative going voltage propagates down the bus. This strong negative going voltage drags a composite wave on the bus (i.e. the combination of the waves of the on-going driver and the off-going driver) back below a low threshold voltage approximately one propagation delay after the switching occurs.
