The Simulation and Modeling Group at AT&T Bell Laboratories has recently created a circuit simulator for dc simulation of their in- house integrated circuits. This simulator, called SFRAME has a number of advantages over Newton-Raphson-based simulation programs such as SPICE. These advantages include global convergence, the ability to find more than one or sometimes even all of a circuit's operating points, and the ability to incorporate the sophisticated bipolar junction transistor models used at Bell Laboratories; running SPICE on circuits incorporating these models has led to severe convergence problems. This research will affect major enhancements to SFRAME, including initialization capability, ability to simulate circuits containing MOS transistors, and identification of the stability of operating points found. It is expected that the work proposed herein will be a starting point for a long and productive industry-university collaboration.

AT T贝尔实验室的仿真和建模组最近创建了一个电路仿真器，用于内部集成电路的直流仿真。 这个模拟器，称为SFRAME有许多优点，牛顿-拉夫逊为基础的模拟程序，如SPICE。 这些优点包括全局收敛，能够找到一个以上的，有时甚至是所有的电路的工作点，并能够将复杂的双极结型晶体管模型在贝尔实验室使用;运行SPICE电路纳入这些模型导致了严重的收敛问题。 这项研究将影响SFRAME的主要增强功能，包括初始化能力，模拟包含MOS晶体管的电路的能力，以及确定工作点的稳定性。预计本文提出的工作将成为长期和富有成效的产学合作的起点。
