Simulating the shift_clk Design in the ModelSim-Altera Software

This ModelSim design example is for the ModelSim-Altera (Verilog) version. To simulate the design in the ModelSim-Altera software, follow these steps:

  1. Download and unzip the file to any working directory on your PC.
  2. Locate the folder in which you unzipped the files to, and open the file in a text editor.
  3. In line 1 of the file, replace <insert_directory_path_here> with the directory path of the appropriate library files. For example, C:/Modeltech_ae/altera/verilog/stratix.
  4. On the File menu, click Save.
  5. Start the ModelSim-Altera software.
  6. On the File menu, click Change Directory.
  7. Select the folder in which you unzipped the files. Click OK.
  8. On the Tools menu, click TCL and click Execute Macro.
  9. Select the file and click Open. The fileis a script file for the ModelSim-Altera software to automate all the necessary settings for the simulation.
  10. The Waveform Viewer appears. Verify the waveform shown in the viewer.
The following figure shows the expected simulation results in the ModelSim-Altera software.
