A Historical Review of Circuit Simulation

Within the Circuits and Systems (CAS) Society, developments in computer-aided circuit analysis and circuit design commenced in the early 1950´s using the earliest digital computers. Initially, computer-aided circuit analysis of linear circuits was used in design optimization, design centering, and in determining the effects of parasitics on circuit performance. Although this use of computer-aided circuit analysis has continued, computer-aided design (CAD) and circuit design automation within the CAS Society are now principally concerned with problems associated with the overall design and evaluation of very large circuits and systems.
