Adding new boards
If you want to add a new boards to Icestudio, first you should support it in Apio. Apio is in charge of running the necessary tools for generating the bitstream for the FPGA, from the verilog sources
Once the board is supported by Apio, proceed to add it to Icestudio. It is just a graphical user interfaces that calls apio when the user needs to build, verify or upload its circuits
Once the board is supported in Apio, adding it to Icestudio is rather easy
The Boards are described by three JSON files, located in the folder resources/boards/boardname
-
pinout.json: Pin numbers, names and type (input, output, inout) -
info.json: Board information: resources, board name, interface... -
rules.json: Automatic connection of unused pins
In addition there are two more OPTIONAL files:
-
pinout.pcf: Board constraints. This is just for documentation purposes (the actual constraint file is automatically generated on the fly when the circuit is being sinthesized -
pinout.svg: Drawing of all the pins
Just create a folder inside resources/boards/ with the name of the board, and insert the configuration files there
Edit the resources/boards/menu.json and add the new board
