Introduction
Migen is a Python module that makes FPGA design possible without VHDL or Verilog. Writing a Migen design for FPGA is like writing Python program. If it's correctly configured with ISE or Quartus, Migen is also capable of generating the bitstream directly.
APF27 and APF51 platforms have been integrated under Migen in July 2014, so designs can be done with it for these APF.
Installing Migen
Requirements
- Python 3.4 minimum
- git
- python setuptools: to use in developpement python module
# On debian: sudo apt-get install python-setuptools
- ISE webpack: to generate bitstream for apf27, apf51
- Quartus web edition: to generate bitstream for apf6sp
installation
Migen is an under developpement python3 module. To install it python 3.4 is required.
- first download the git tree:
$ git clone https://github.com/m-labs/migen.git
- Then install it as developpement module:
$ cd migen $ sudo python setup.py develop
- To be up-to-date with the github tree, do not forget to pull fresh version regularly :
$ cd migen $ git pull
