IBIS Schematic Library Part Generator

IBIS (I/O Buffer Information Specification) is a standard for behavioral models of integrated circuit input/output analog characteristics. Many IC vendors provide IBIS models for ICs, especially for those operating at high speeds (50 MHz or greater). The models are used for signal integrity simulation. The IBIS model files also contain sufficient information to generate schematic symbols. The Mental Automation IBIS utility allows a user to take a file with the extension .ibs and produce a BUILD utility input file (.LIB) that can be used to produce a SuperCAD part symbol. This utility is very useful for generating symbols for parts that have a large pin out, for example DSPs, microprocessors, and communication chips.

To get a copy of the IBIS utility click here:

IBIS_To_Lib

To use the utility, run it anywhere on your hard drive and load an IBIS file by entering the file name or clicking on the Browse button:

After the utility runs, edit the package and description fields of the resulting .LIB file, and then copy this to the LIB directory of SuperCAD. Then run the BUILD utility from the UTILITIES menu. Note that the utility only produces rectangular symbols. By default GND pins are placed on the lower edge of the symbol , and VCC pins on the top.
