Without further ado let us continue to the counter example. Mit dieser soll sich die Funktionalität des Modules vor der Synthese mittels Simulation prüfen lassen. To avoid this cancel and sign in to.

Like a standard VHDL source file the Xilinx tools automatically generate lines of VHDL code in the file to get you started with circuit input definition. The one you will want to select is titled Behavioral Simulation. Xilinx points to XAPP199 and design and simulation guides for various tool releases.

Open up the nearly created combtb file and add the following VHDL statements to instantiate a copy of the comb module and create a simple test bench.
