The demonstration test bench instantiates the generated FIR Compiler core.
After generating the demonstration test bench it must be set as the top-level simulation object. This is done using the Sources pane. Expand the Simulation sources folder and under the core instance the test bench object is visible as tb_<component_name> . Select the file, right-click and select Set as Top . Simulation can now be launched and the test bench is used to drive the core instance.
