ASTAP

ASTAP (Advanced Statistical Analysis Program) was a general purpose analog electronic circuit simulator developed primarily for in-house use by IBM from 1973 on. It was a powerful program used for simulation of integrated circuit designs, and their analysis with statistical variations of the manufacturing process. In combination with the built-in Monte Carlo method capabilities it allowed prediction of the performance of electronic circuits under a wide range of material parameters and temperatures. ASTAP was designed to run on IBM Mainframe computers.
