Abstract

Multiplier arrays are designed as regular itera- tive arrays which include Booth encoders, Booth muxes and carry save adders' (CSA). Uncontrolled constants feeding into the multiplier array results in untestable circuits within the Booth mux and CSA circuits. This invention provides a high test cover- age for multiplier arrays.
