Troubleshoot Binding Update Issues

You can face following issues when updating bindings:

• Ignoring Route Cells
• Updating Instance Bindings after Running MakeCell

Ignoring Route Cells

If route cells are set to be ignored during Update Binding but some devices have stop layers defined while others do not, you can do either of the following for the cells to be processed appropriately during an Update Binding run.

• Add the stop layer for the devices that do not have them already defined and run Update Binding again.
• Run Update Binding without ignoring route cells and manually add ignores on route cells after they have been reported by Update Binding.

See validLayers – Stop Layers Specification.

Updating Instance Bindings after Running MakeCell

If you run the MakeCell command after flattening a device, the Update Binding command may not be able to update the instance bindings to reflect the change. To enable the Update Binding command to effectively update the instance bindings:

1. In the Navigator assistant or layout canvas, right-click the made cell instance and choose the Hierarchy – Unset Transparent command to prevent the binder from binding devices inside the made cell.
2. Right-click the made cellview and edit it to rename the terminals to match the schematic nmos device.
3. Relaunch Layout XL on the top cellview, where the made cell is instantiated.
4. Run the Update Binding command using the default options.
