To determine whether your model is compatible for resource sharing:
Before generating code, run checkhdl
and
eliminate general compatibility issues.
In the Configuration Parameters dialog box, on the HDL Code Generation pane, select Generate optimization report.
Set the sharing factor for the DUT and generate code.
After code generation completes, inspect the Optimization Report. The report shows incompatible blocks or other conditions that can cause a resource sharing request to fail.
If the Optimization Report shows problems, fix them and repeat these steps.
