Abstract:

The development of digital computer programs for automated circuit and component analysis is reported. This work resulted in the development of the PREDICT and TREAT programs for the IBM 7090. PREDICT is an automated digital computer program for determining transient circuit response which will accept a topological description of a large circuit, evolve and solve the necessary circuit equations, and produce the time history of specified voltages and currents. Transistors, diodes, and capacitors in transient radiation environments are represented by equivalent circuits. TREAT is a system of six programs for the automatic processing of data on the effects of transient and steady-state radiation on transistor, diode and capacitor parameters. The program treats actual and typical device information, evaluates permanent damage to devices, and processes dosimetry information. From actual or typical radiation environment and device data, the theoretical response of certain important device parameters during irradiation can be computed. This output of TREAT can be used directly as an input to PREDICT. Author
