Mini-MSINC-a minicomputer simulator for MOS circuits with modular built-in model

This correspondence describes Mini-MSINC, a minicomputer simulator for metal-oxide-semiconductor (MOS) integrated nonlinear circuits. Mini-MSINC runs on a HP2100-series minicomputer with 32K words of memory and simulates the nonlinear d.c. and transient responses of MOS transistor circuits. A test circuit of 26 transistors with 150 time points was simulated in 10 min. A modular-model program feature facilitates the alteration and replacement of semiconductor device models. Models other than MOS transistors can be implemented within the constraint of four external and two internal nodes.
