+This test requires LiteX 2022.08. You will need to define `DEBUG` in the `boothmul.v`
+file for the logic analyzer to work correctly.
+
+Run `python3 soc.py` to build the design. Afterwards, load the design. Then run
+
+    litex_server --uart --uart-port /dev/ttyUSB1
+
+afterwards run
+
+    python3 hardtest.py
+
+This will generate two .vcd files, which you can check to verify that the multiplier
+is working.
