Check your settings on the main HDL Code Generation settings page, for the Target. If the
Test Bench is greyed out, you have not chosen a subsystem to generate HDL for, but are
generating HDL for the entire model. If the entire model is the DUT, then there is no part
of the model left to act as a testbench, so the Test Bench settings are disabled.
