This example is built specifically for the basys3 and demonstrates a greater variety of I/O
|
|
then previous designs. It also demonstrates symbiflow's support for code written in System Verilog
|
|
as well as its support of dictionaries in XDCs. To build this example run the following commands:
|
|
|
|
.. code-block:: bash
|
|
:name: example-watch-basys3
|
|
|
|
make -C timer
|
|
|
|
|
|
At completion, the bitstream is located in the build directory:
|
|
|
|
.. code-block:: bash
|
|
|
|
cd timer/build/basys3
|
|
|
|
Now, you can upload the design with:
|
|
|
|
.. code-block:: bash
|
|
|
|
openocd -f ${INSTALL_DIR}/${FPGA_FAM}/conda/envs/${FPGA_FAM}/share/openocd/scripts/board/digilent_arty.cfg -c "init; pld load 0 top.bit; exit"
|
|
|
|
After downloading the bitstream you can start and stop the watch by toggling switch 0 on the board.
|
|
Press the center button to reset the counter. The following gives a visual example:
