Little python helpers for parsing through Xilinx build outputs.

Install

This is pure python, no dependancies. Only tested on linux (debian wheezy).

Using pypi:

pip install xmsgs-tools

Or, locally,

python setup.py install

Usage

Do xmsgsprint -h or xmsgsdiff -h for usage. Examples:

bnewbold@ent$ xmsgsprint test/run_a/xst.xmsgs -t severe -f

HDLCompiler:413: Result of 32-bit expression is truncated to fit in 4-bit target.
HDLCompiler:413: Result of 9-bit expression is truncated to fit in 8-bit target.

Notes

'fulltext' is not a unique identifier; many warning texts are repeated

See also, XReport GUI tool.

TODO

• Are message numbers unique across tools? If not, need more sophisticated filtering.
• Collapse redundant warnings (eg, every bit on on the same port)
