Application of the optimization program AOP to the design of memory circuits

The memory cycle time of an IGFET read-only memory cell is designed using AOP, a program for automated and interactive optimization of electrical networks. It is shown how AOP allows the user to specify multiple performance objectives and to request analysis, and/or adjoint sensitivity computation, and/or automated optimization for networks described in the ASTAP input language. A. procedure is given for applying optimization to switching circuit design, and a summary is given of the hard experience gained from applying AOP to a practical problem in LSI design.
