Project Description

The aim of the project is to recreate the schematic of a PolarFire FPGA development board (image 1), but in a different physical form-factor.

The electrical design should be based on the provided schematic for the PolarFire design, but the circuitry needs to fit onto a board that is the same size and shape as the Ultra96 board (image 2).

Milestones

1. Check over the imported PolarFire board schematic and tidy up any obvious import errors [Done]
2. Add the same connectors that are in the Ultra96 reference board to the new PolarFire design: [Done]
   1. 'Low speed connector' (J5 [on Ultra96 board])
   2. 'High speed connector' (J4 [on Ultra96 board])
3. Remove the PCIe connector (J6) and replace it with a MiniPCIe connector
4. Remove the Ethernet connectors (J1 & J2), and connect these signals to the new 'high speed connector' (note that the exact pinout is not too important yet - it is up to us to define) [Done]
5. Remove the Raspberry Pi header (J26) and map these signals to equivalent pins on to the new 'low speed connector' (the pinout should be as similar as possible to that of the Ultra96 board)"
6. Modify the dimensions of the board to match the Ultra96 reference design (see appendix 1)
7. Move the high speed and low speed connectors to the same location as the Ultra96 reference board
8. Identify whether the components in the PolarFire schematic will fit onto the new board size
