A modified version of the computer programme SINC-S is described which permits the user to specify independently up to 30 different device temperatures in a given problem when the proper control statement is included. An additional option is an algorithm for the steady-state solution of a non-linear network with periodic inputs, so that realistic system operation may be simulated. The programme may be used to provide more accurate simulation of circuits where large temperature gradients are present, and to furnish input data for other thermal analysis programmes

“…Another program in which this conversion was successfully done was Mini-MSINC [2]. Mini-MSINC, developed for an HP2100 minicomputer system with a DOS III operating system, was derived from TIME [34], SINC [12], and MSINC [35], all developed for large computer systems. To fit Mini-MSINC into the 32-kword memory of the HP2100, it was necessary to overlay memory through five overlay segments on disc and to extensively modify the common array allocation with linked lists [30].…”

Interactive-mode circuit simulation and batch-mode circuit simulation on minicomputers are compared relative to the simulator architecture and required simulation speed. The more significant speed-and memory-dependent algorithms used in circuit simulators are compared in detail. Also compared are the execution speeds of several different minicomputer systems, including the HP2100, the PDP 11 /45, and the PRIME 400. The speed and memory requirements of these minicomputers executing BIAS-D are compared to an IBM 370/168 also executing BIAS-D. A new method for computing small-signal frequency response is introduced. Because complex arithmetic is not required, this technique is particularly suited to minicomputer simulators and requires minimal additional memory when implemented in a circuit simulator with a transient analysis capability. The frequency response of both linear and nonlinear circuits can be modeled, as can that of high-Q circuits. Magnitude and phase errors of less than 1 percent and 0.5 degrees, respectively, are easily attainable. Speed ratios between this technique and a conventional ac analysis vary depending on the circuit Q. For circuits with Q less than 1, this ratio is typically 10:1. UNCLASSIFIED

The simulation of electronic circuits by computer has become an important part of present‐day circuit analysis and design, especially in the area of integrated circuit design. One of the goals in computer simulation of integrated circuits is to have a program ‘package’ for which the input consists of chip fabrication data (mask dimensions, impurity profiles, material data such as carrier lifetimes) and the output displays the complete circuit response. This requires both an efficient modelling approach and a fast circuit analysis method. In this paper a simulation method is described which generates dc responses (in the form of operating points or transfer characteristics) of transistor circuits directly from physical parameter data. The basis of the method is a two‐dimensional piecewise‐linear approach to the dc modelling of bipolar transistors. The model is directly used in a piecewise‐linear circuit analysis program to simulate the dc response of a given circuit.
