TL;DR: Computational time that is required for different levels of device models is illustrated together with the savings achieved using a device bypass scheme and table lookup models.
Abstract: SPICE2 has proven to be an effective electronic circuit simulation program. Nonetheless, needs exist for faster computational performance and the ability to simulate economically larger circuits, especially large MOS circuits. Tradeoffs are necessary between accuracy and memory with circuit size and between accuracy and computational speed. For a bench mark example of a binary-to-octal decoder, the above aspects are illustrated. In addition, computational time that is required for different levels of device models is illustrated together with the savings achieved using a device bypass scheme and table lookup models.

TL;DR: A new method for computing electronic circuit small-signal frequency response, when implemented in a circuit simulator that has a transient analysis capability, requires minimal additional memory and software.
Abstract: A new method for computing electronic circuit small-signal frequency response is introduced. This method, when implemented in a circuit simulator that has a transient analysis capability, requires minimal additional memory and software. Because complex arithmetic is not required, this method is particularly suited to minicomputer simulators. The frequency response of both linear and nonlinear circuits is possible. The frequency response of high-Q circuits, although more time consuming, is also possible. Magnitude and phase errors of less than 1% and 0.5 degrees, respectively, are easily attainable. Speed ratios between this method and a conventional ac analysis vary depending on the circuit Q. For circuits with Q less than 1, this ratio is typically 10:1.
