Overriding Instance Bindings

You can override a cellview binding to use a Virtuoso config or schematic view instead of a text cellview. The drop-down list in the Binding Override column shows the name of the corresponding library, cell, and config or schematic view.

The Virtuoso cellviews for which either of the following conditions is satisfied are displayed in the Binding Override column:

• Aconfig view is available and the design sub-top (schematic or text) cell name is the same as the cell or block name
• Aschematic view is available and the cell name is the same as the cell or block name

To switch instance bindings:

1. Add xrun files in the Use Existing xrun Files section.
2. Add Virtuoso directories in the Virtuoso Directories section.
3. Click Update on the toolbar to update the hierarchy after adding all the xrun scripts and Virtuoso directories.
   CLIPS elaborates the design to identify the Virtuoso cellviews available for the cells listed in the Cell column.
   
   
   You can find all the Virtuoso config or schematic views whose schematic DUT name matches the module name of digital text file by selecting Enable Searching Mismatched DUT Name in the Options menu.
4. For each cell for which you need to override the cellview binding, select the config or schematic cellview name from the drop-down list in the Binding Override column.
   
   
   You can specify a testbench to display the design hierarchy. From the hierarchy, you can switch any instance with available binding override choices to an HED configuration. Then, AMS-UNL is called to export the HED configuration as an IP and assemble the IP together with the testbench.
