Getting Started with the Interposer Canvas


This guide explains the use of the Interposer Canvas with the Analog Discovery Studio. The Interposer Canvas is used to host one of our FPGA boards and user-designed circuitry. The Interposer Canvas connects to the Analog Discovery Studio through the magnets beneath each of the four standoffs in the corners of the canvas. The Interposer Canvas includes the following features:

  • One 300 tie-point solderless breadboard
  • One 50 tie-point power rail
  • Four power supply indication LEDs
  • One 24 tie-point breadboard power supplies contact points


  • Interposer Canvas
  • USB Cable to connect to FPGA board
  • 4 standoffs for mounting the FPGA board above the Interposer Canvas
  • 8 screws for mounting the FGA Board and standoffs to the Interposer Canvas


1. Setup


The Interposer Canvas is an optional accessory for the Analog Discovery Studio. The Interposer Canvas is attached to the Analog Discovery Studio through magnets beneath each of the four standoffs in the corners. To begin setting up install the four black standoffs in the designated location for your FPGA board. In this example, we are installing a Nexys A7 FPGA board onto the Interposer Canvas. Use four of the provided screws to fasten the spacers in place.

Unplug your Analog Discovery Studio board from both the USB and power connectors. Place the Interposer Canvas back into its slot, connect the Analog Discovery Studio to the host computer using the included USB Type B cable. Connect the included 15V power supply to the Analog Discovery Studio and turn on the Analog Discovery Studio by flipping the switch on the left-hand side of the platform.

Ensure that the Analog Discovery Studio is turned OFF before installing the Interposer Canvas board. Plugging a Canvas board into a powered Analog Discovery Studio can cause damage to either the Analog Discovery Studio, the Interposer Canvas, the FPGA board, or your custom circuitry.

2. Out of the Box Demo Mode


Each compatible FPGA board comes with an “Out-of-Box” demo programmed into nonvolatile memory, which can be used to show everything is working correctly. To run this demo, ensure that the programming mode jumper for the board is set to QSPI (or in the case of the Arty A7, just that the jumper is installed) and power the board on. The board will boot, and you will see several LEDs light up. The behavior of the Out-of-Box demo differs depending on the board, so make sure to review the board's documentation for more information on what it does.
