SCons tools for Xilinx

About

This is a collection of SCons tools for automating the Xilinx build flow.

The package makes a set of Builders available, which you can use in a SConstruct or SConscript file:

Builder	Source files	Target files
Coregen	.xco	.ngc, .v
XstSynthesis	.v, .vhd	.ngc
NgdBuild	.ngc, .ucf	.ngd
Map	.ngd	_map.ncd
PlaceRoute	_map.ncd	.ncd
BitGen	.ncd	.bit

Example usage:

env = Environment(tools=['xilinx'])
env.XstSynthesis('out.ngc', ['source.v', 'module.v'])

To see in more detail how the tools can be used, look at the example project.

Installation

Copy the entire site_tools/xilinx tree to a location you like.

SCons will find it in one of the following locations by default:

• ./site_scons (relative to your SConstruct/SConscript)
• $HOME/.scons/site_scons
• /usr/share/scons/site_scons

If you choose a different location, you can point SCons to it using the --site-dir command line option or by passing it as the toolpath argument to the Environment constructor (read more here).

The file copying is handled for you if you call:

scons install [--user|--prefix=<location>]

If the --prefix option is given, it specifies the directory into which the site_tools/xilinx tree will be copied. If it is not given and the --user flag is set,$HOME/.scons/site_scons will be used, /usr/share/scons/site_scons otherwise.
