Das Buch bietet eine praxisorientierte Einführung in die Hardware-Beschreibungssprache VHDL zum rechnergestützten Entwurf digitaler Systeme.

Part 7: A practical example - part 3 - VHDL testbench; In an earlier article I walked through the VHDL coding of a simple design. In this article I will continue the process and create a test bench module to test the earlier design. The Xilinx ISE environment makes it pretty easy to start the testing process.

The code simulates and works well without the reset and clk process in the code below. But after inserting the process(reset,clk) the h_count and v_count counters stop counting and are driven to XXXXX undefined in simulation. The process is the key structure in behavioral VHDL modeling. A process is the only means by which the executable functionality of a component is defined.

The VHSIC Hardware Description Language (VHDL) is a formal notation design style (large number of concurrent VHDL statements and processes, leading to

The dataflow representation describes how data moves through the system. This is typically A process block contains statements that the VHDL compiler executes sequentially. Statements inside the process block may describe the working of the entity or a portion of the entity.

Behavioral program style. Normally uses VHDL “processes”. Each VHDL process executes in parallel with other VHDL processes and concurrent statements.

VHDL Process Using XILINX To implement VHDL designs, we will use Xilinx. Xilinx is one of the best providers of programming logic devices. It is a tech company based on states. The VHDL structures we will look at now will all be inside a VHDL structure called a ‘process.’ The best way to think of these is to think of them as small blocks of logic. They allow VHDL to break up what you are trying to archive into manageable elements. So let’s look at this example that has an IF statement inside it. VHDL allows one to describe a digital system at the structural or the behavioral level.
