Abstract
A method, a computer program, and an apparatus are provided to protect transmission gates in a multiplexer (mux). Because transmission gates are much faster than the more convention AND-OR arrays, transmission gate usage in muxes are being used more often in high speed circuitry. However, transmission gate have a significant problem in that short circuit are possible for situations where there is not a one-hot select signal. Therefore, to eliminate the problem, logic gates are utilized specifically during Power-On Reset (POR) to force a one-hot selection to prevent any possible short circuits.
