Topological Properties of Some Integrated Circuits for Very Large Scale Integration Chip Designs

This talk presents topological properties of integrated circuits for Very Large Scale Integration chip designs. These circuits can be implemented in very large scale integrated circuits, such as those in high performance microprocessors. Prior work considered basic combinational logic functions [1] and produced a mathematical framework based on algebraic topology for integrated circuits composed of logic gates [2]. Prior work also produced an historically-equivalent interpretation of Mr. E. F. Rent's work for today's complex circuitry in modern high performance microprocessors, where a heuristic linear relationship was observed between the number of connections and number of logic gates [2]. This talk will examine topological properties and connectivity of more complex functionally-equivalent integrated circuits. References: [1] E. Hiteshue, K. Irvin, M. Lanzerotti, G. Vernizzi, J.
