Hardware Design Framework based on python and MyHDL
Project description
A very preliminary documentation (work-in-progress) is available at: http://hnikolov.github.io/pihdf_doc/
Install pihdf
To install pihdf in editable mode:
$ sudo python setup.py develop
pihdf depends on the following python packages: myhdl, simplejson, coverage, nose. These will be installed during the installation of pihdf if not present on your system.
Note: These packages will not be un-installed if you un-install pyhdf.
Un-install pihdf
To un-install pihdf:
$ sudo python setup.py develop --uninstall
Then, remove the command-line script module from its location:
$ which module | xargs sudo rm
Co-simulation, waveform and dotty viewers
For co-simulations, pihdf uses the Icarus iverilog simulator. GTKWave is the waveform viewer used in pihdf. For structured designs, pihdf generates also the design topology (i.e., HW modules interconnections) as a .dot file. To viasualize it, you can use xdot program. Install all programs by executing:
$ sudo apt-get install iverilog gtkwave xdot
Create myhdl.vpi
For co-simuations, myhdl uses a .vpi interface. To create the myhdl.vpi file used with Icarus, download the source of myhdl. Then,
$ cd [myhdl-folder]/cosimulation/icarus/ $ make
Make sure that file myhdl.vpi is copied to directory /.pihdf!
Notes
pihdf requiers myhdl_lib (https://github.com/nkavaldj/myhdl_lib)
The command-line tool module makes use of the very convenient package docopt (https://github.com/docopt/docopt), which is copied in the pihdf repository.
