Design of combinational and sequential switching circuits at the sub-system level

Current trends in microelectronic technology, and the rapid increase in medium and large-scale integration, have motivated the design of digital systems at the sub-system level, and made traditional discrete gate techniques obsolete in many situations. The use of devices such as read-only memories (ROMs), programmable logic arrays (PLAs) and universal logic modules (ULMs), has considerably influenced the design philosophy. The designer may therefore find himself confronted by entirely different problems from those encountered in the past, some of which will be tackled in this thesis. [Continues.]
