| # IDDR/ODDR test |
| |
| These tests are meant to check correct support for IDDR and ODDR primitives as well as their operation in real hardware. |
| |
| ## The hardware test |
| |
| 1. Build the test named `ioddr_hw_test_basys3` and upload the bitstream to a Basys3 board |
| 2. Make wire loop connections on JC connector so that pins 1,7 2,8 3,9 and 4,10 are shorted. |
| |
| LED7 should blink continuously indicating that the bitstream is working. |
| |
| LEDs 0 to 3 indicate error in data transmission. They all should remain off while the shorting wires are connected. |
