ASTAP Diode Model Generator Program

A program is disclosed that generates an ASTAP (Advanced Statistical Analysis Program) diode model from the electrical specifications of the diode. This program saves time in hand calculating the diode model from the electrical specifications and produces accurate diode models.

The function of this program is to take the electrical specifications of a diode and generate an output file which contains the ASTAP code for that diode. The user inputs the parameters of the diode in a script-like language, as shown in Fig.
1. Fig. 1 is a sample listing of parameters for a 1000V/4A ultra-fast diode. The program reads in the file and interprets the '.*' command as a comment or the input listing and the program ignores that line. The values for the input file can be in any valid ASTAP units.

Fig. 2 shows the output listing from the program using the input file from Fig.
1. The output listing is an ASTAP diode model from the given electrical specifications from the input file. This diode model will meet the electrical specification on the diode.

The program is written in VSPASCAL V1.0 and runs on TSO and VM operation systems. This program is used in conjunction with ASTAP. The program is written with a set of procedures executed sequentially. The program also has a substantial amount of error checking for the input file and user-friendly error messages.

Prior to this program, ASTAP diode models were hand calculated to obta...
