#FLOODED IN PRO II SIMULATION SOFTWARE#
WebPACK ISE software automates the simulation process by creating and launching a simulation macro file (a “.do” file, or in this case an “.fdo” file). This will bring up the Model Technology MXE dialog box. In the Process window, double-click on “Simulate Behavioral VHDL Model.” The –all property runs MXE until the end of the testbench. In the Simulation Run Time field, type “–all” and hit OK.īy default, MXE will only run for 1us.
#FLOODED IN PRO II SIMULATION SIMULATOR#
In the Process window, expand the ModelSim simulator by clicking then right-click on “Simulate Behavioral VHDL Model.” Select “counter_tb.tbw” in the ISE Source window. Now that the testbench is created, you can simulate the design. To make changes to the waveform used to create the testbench, double-click on “counter_tb.tbw.” The ISE Sources in Project window should look like Figure 4-12.į IGURE 4-12: NEW SOURCES IN PROJECT WINDOW Set the Pattern Wizard parameters to count up from 0 to 1111 (see Figure 4-10). Set the RESET cell below CLK cycle 2 to a value of “0.”Ĭlick the yellow COUNT cell under CLK cycle 1 and click the Pattern button to launch the Pattern Wizard. Set the RESET cell below CLK cycle 1 to a value of “1.” From this Pattern window, you can enter a value in the text field or click on the Pattern button to open a Pattern Wizard. Open a pattern text field and button by double-clicking on a signal’s cell or single-clicking on a bus cell. When entering a stimulus, clicking the left mouse button on the cell will cycle through the available values for that cell.

Note that the blue cells are for entering input stimulus and the yellow cells are for entering expected response. Set initialize timing as follows and click OK: The “Initialize Timing” box sets the frequency of the system clock, setup requirements, and output delays. The HDL Bencher tool now reads in the design. Review the information and click the Finish button.

The testbench is going to simulate the counter module, so when asked which source you want to associate the source with, select “Counter” and click the Next> button. PROGRAMMABLE LOGIC DESIGN - QUICK START HANDBOOK
