How to quickly get started with Hummingbird v2: how to simulate other test files

---

Preface

  When simulating on Ubuntu, I found that the official manual seemed to only be able to simulate the add program, so I went to the Internet to find information, but there seemed to be no explanation in this regard. Therefore, I write this blog after fumbling around.
  If you don’t know how to configure Ubuntu, please see Hummingbird v2 Quick Start Ubuntu Environment Configuration .

Implementation

  First we open e203_hbirdv2 under home, and then enter the vsim folder. After compilation, we can see that the vsim folder looks like this:
  After that, we open the Makefile (download vim in advance), as shown in the figure:

  Press the E key to enter text editing:

  Press the i key to start editing , find TESTNAME, we can see that it was originally rv32ui-p-add (I have changed it to addi in the picture above). After changing it to the file name you want to simulate, exit the editing mode, enter: wq to save and exit.
  Finally, open the terminal under the vsim folder, enter make run_test SIM=iverilog, and press Enter. You can see the following picture, indicating success:

  After entering make wave SIM=iverilog, you can call up the waveform chart (the test bench has a written program):
  You can see that the test of addi is in the upper middle part. Wave file. At this point, the steps are completed.
