1.4.5. Configuring LineSim to Use Intel IBIS Models

You must configure LineSim to find and use the IBIS models for your design. To do this, add the location of your .ibs file or files to the LineSim Model Library search path. Next, you apply a selected model to a buffer in your schematic.

To add the Quartus® Prime software’s default IBIS model location, <project directory>/board/ibis, to the HyperLynx* LineSim model library search path, perform the following steps in LineSim:

  1. From the Options menu, click Directories. The Set Directories dialog box appears. The Model-library file path(s) list displays the order in which LineSim searches file directories for model files.

  4. Browse to the default IBIS model location, <project directory>/board/ibis. Click OK.
  5. Click Up to move the IBIS model directory to the top of the list. Click Generate Model Index to update LineSim’s model database with the models found in the added directory.
  6. Click OK. The IBIS model directory for your project is added to the top of the Model-library file path(s) list.
  7. To close the Set Directories dialog box, click OK.
