2.4.6. Integrating Intel IBIS Models into LineSim Simulations

When the location for IBIS files has been set, you can assign the downloaded or generated IBIS models to the buffers in your schematic. To do this, perform the following steps:
  1. Double-click a buffer symbol in your schematic to open the Assign Models dialog box. You can also click Assign Models from the buffer symbol’s right-click menu.

  2. The pin of the buffer symbol you selected should be highlighted in the Pins list. If you want to assign a model to a different symbol or pin, select it from the list.
  3. Click Select. The Select IC Model dialog box appears.

  4. To filter the list of available libraries to display only IBIS models, select .IBS. Scroll through the Libraries list, and click the name of the library for your design. By default, this is <project name>.ibs.
  5. The device for your design should be selected as the only item in the Devices list. If not, select your device from the list.
  6. From the Signal list, select the name of the signal you want to simulate. You can also choose to select by device pin number.
  7. Click OK. The Assign Models dialog box displays the selected .ibs file and signal.
  8. If applicable to the signal you chose, adjust the buffer settings as required for the simulation.
  9. Select and configure other buffer pins from the Pins list in the same manner.
  10. Click OK when all I/O models are assigned.
