processing on the microcontroller and greatly simplify the motor driver.
+## Gate Level Testing
+
+Instructions for running gate-level validation:
+
+Make sure submodules are correct:
+```
+git submodule init
+git submodule update
+```
+
+Gate-level testing directory:
+
+```
+cd verilog/dv/caravel/rapcore/io_ports
+```
+
+```
+make clean
+make
+```
