ideal-spork

This is WIP

Ideal spork is a nmigen board builder and Boneless SOC builder.

Requirements

The nmigen suite and the Boneless-CPU

nmigen : (https://github.com/nmigen/nmigen)
nmigen-soc : (https://github.com/nmigen/nmigen-soc)
nmigen-boards : (https://github.com/nmigen/nmigen-boards)
nmigen-stdio : (https://github.com/nmigen/nmigen-stdio)
Boneless-CPU : (https://github.com/whitequark/Boneless-CPU)

FPGA development programs

Current development is on a TinyFPGABx this uses the following software

yoysys : (https://github.com/YosysHQ/yosys)
nextpnr : (https://github.com/YosysHQ/nextpnr)
icestorm : (https://github.com/cliffordwolf/icestorm)

With this software installed ideal_spork provides some board tooling

Installation

Clone this repository

> git clone https://github.com/zignig/ideal-spork.git
> cd ideal-spork
> python setup.py develop --user

This will install the library and create a program called spork.

bash> spork

usage: spork [-h] [-v] [-vv] [-vvv] [-d DIRECTORY]
             {init,info,console,build,status,update,list,burn,program,gatesim,tools}
             ...

spork is a nmigen board build helper

positional arguments:
  {init,info,console,build,status,update,list,burn,program,gatesim,tools}
    init                Create files for a new board
    info                Get information from the base board
    console             Attach to a new console (UMFINISHED)
    build               Build gateware and program onto the board (UNFINISHED)
    status              Get the status of the current spork (UNFINISHED)
    update              Update all the fixed assets (UNFINISHED)
    list                List available boards
    burn                Add the given firmware to boot image
    program             Upload the given firmware onto the board
    gatesim             Run a gate simulation of the board
    tools               Development Commands

optional arguments:
  -h, --help            show this help message and exit
  -v                    Warn Logging Level
  -vv                   Info Logging Level
  -vvv                  Debug Logging Level
  -d DIRECTORY, --directory DIRECTORY
                        Directory for spork file

You probably want "spork init <project name> -i"

> python -m ideal_spork --dumpall
