To install
- clone the repo
- Open Vivado
- click Open Project
- navigate to the repo and select the .xpr file
Settings
- select Settings (blue cogwheel)
- select Tool Settings | Project
- in Default Project Directory, select "Specify project directory" and select the directory for this project
- click OK
To program and run
- find "SYNTHESIS" in left hand pane
- click "Run Synthesis" next to Green arrow
- see upper right corner in menu bar for status e.g. "running synth_design" with a cycling green circle
- takes 1-2m
- get dialog box "Synthesis Completed"
- ensure "Run Implementation" selected
- click OK
- get dialog box "Launch Runs"
- set Number of jobs to the number of cores your PC has (e.g. 8)
- click OK
- see upper right corner in menu bar for status e.g. "initializing Design" with a cycling green circle
- takes 1-2m
- get dialog box "Implementation Completed"
- select "Generate Bitstream"
- click OK
- get dialog box "Launch Runs"
- click OK
- see upper right corner in menu bar for status e.g. "Running write_bitstream" with a cycling green circle
- takes 1-2m
- get dialog box "Bitstream Generation Completed"
- select "Open Hardware Manager"
- if No hardware target is open:
- ensure your FPGA is connected via USB-micro and powered on
- click "Open Target" either in left hand pane or in green bar at top of window
- get a dropdown menu
- click "Auto Connect"
- get dialog box, takes 5 - 10s
- Hardware pane should have your FPGA in it and indicate "Connected"

- click "Program device"
- get dialog box "Program Device"
- click "Program"
- takes 1-2s
To test
- There are 2 buttons on the FPGA board BTN0 and BTN1
-
There are 3 LEDs: LD0, LD1 and LD2
- LD0 is a tri-color led and should be lit (blue)
- LD1 and LD2 are off (both green)
-
press BTN0 => LD1 should turn on
-
release BTN0 => LD1 should turn off
- LD0 should stay lit (blue) and LD2 be off
-
press BTN1 => LD2 should turn on
-
release BTN1 => LD2 should turn off
- LD0 should stay lit (blue) and LD1 be off
-
press both BTN0 and BTN1 => both LD1 and LD2 should turn on
- release both buttons => both LEDs should turn off
