| # 7-series support |
| |
| This directory contains 7-series specific architecture definitions. |
| |
| ## Examples |
| |
| The following examples are testing on basys3: |
| |
| * xc7/tests/buttons - Connects switches/buttons to LEDs |
| * xc7/tests/simple_ff - Connects the inputs and outputs of an FF to switches and LEDs |
| * xc7/tests/counter - Displays a counter on 5 LEDs |
| * xc7/tests/ram_test - Runs a simple RAM test against a 64x1 DRAM instance. Results arrive on UART (500k baud). |
| |
| ### Running examples |
| |
| After creating a cmake build directory (running make env in root), cd into example and run: |
| |
| ``` |
| make <example name>_<board name>_bin |
| ``` |
| |
| to generate a bitstream. To program the bitstream via OpenOCD run: |
| |
| ``` |
| make <example name>_<board name>_prog |
| ``` |
| |
| Additional targets are best explored via tab completion. |
| |
| Full example for buttons: |
| |
| ``` |
| git clone https://github.com/SymbiFlow/f4pga-arch-defs.git |
| cd f4pga-arch-defs |
| make env |
| cd build |
| cd xc7/tests/buttons |
| make buttons_basys3_bin |
| ``` |
