How to convert IBIS Models into PSpice Model ?

DesignTech

I/O Buffer Information Specification known as IBIS is used to behaviorally represent the Input, Output, and I/O buffers of digital ICs. These models characterize a buffer using a collection of DC data (current vs. voltage), as well as transient data (voltage vs. time) in form of I-V and V-t tables.

PSpice users perform SPICE simulation on the complete design, which includes digital ICs whose pin buffer models are available in the IBIS format. To achieve this, the IBIS model needs to be converted to the PSpice model. The translated PSpice model is a sub-circuit that converts the V-I and V-t data from IBIS file to PSpice compatible tables.

The resulting PSpice subcircuit does not have any power pins because they are already included in the subcircuit.

To translate an IBIS model using Model Editor:

  1. Open Model Editor.
  2. Choose Model – IBIS Translator. The IBIS translator appears.

In the IBIS/DML File field, specify a .ibs or .dml file to be translated in the IBIS translator dialog box. You can use the Browse button to select the file.
A dialog box appears for IBIS to DML generation settings.

Select:

  • Always regenerate DML to regenerate DML files. IBIS files are first converted to their equivalent dml files, and the dml files are then read. If Always regenerate DML is not selected, IBIS to DML conversion is not done if a dml file with the same name is already available and the dml is more recent that the IBIS file.
  • Make model names unique to create models with unique names by prepending the file name to the model name.
