The Development of a Prototype CMOS (Complementary Metal Oxide Semiconductor) Circuit Simulator.
Abstract
This thesis effort designed and developed a prototype CMOS circuit simulator written in FORTRAN 77. The program is totally interactive, and prompts the user for all required information to generate the circuit and input vector files. Output is in the form of two text files, one detailed, and the other, tailored by the user to provide only specific information. The prototype was designed and implemented to model CMOS circuits of up to 100 components, with four basic component types defined. Circuit timing is also simulated, with a variable transistor switching delay capability. Analysis of the simulator was performed on a DEC VAX 11/785 using the UNIX operating system and the UNIX F77 FORTRAN compiler. Tests were run on two types of circuits, constructed from basic logic gates, and varying in size from two to 68 components. Overall execution times of 37 to 78 msec per component were experienced.
