5.2.5.4. Excluded Resources

The Excluded Resources feature allows you to easily exclude specific device resources such as DSP blocks or M4K memory blocks from a Logic Lock (Standard) region.

For example, you can assign a specific entity to a Logic Lock (Standard) region but allow the DSP blocks of that entity to be placed anywhere on the device. Use the Excluded Resources feature on a per-Logic Lock (Standard) region member basis.

To exclude certain device resources from an entity, in the Logic Lock (Standard) Region Properties dialog box, highlight the entity in the Design Element column, and click Edit . In the Edit Node dialog box, under Excluded Element Types , click the Browse button. In the Excluded Resources Element Types dialog box, you can select the device resources you want to exclude from the entity. When you have selected the resources to exclude, the Excluded Resources column is updated in the Logic Lock (Standard) Region Properties dialog box to reflect the excluded resources.

Note: The Excluded Resources feature prevents certain resource types from being included in a region, but it does not prevent the resources from being placed inside the region unless you set the region’s Reserved property to On. To indicate to the Fitter that certain resources are not required inside a Logic Lock (Standard) region, define a resource filter.
