pyXar

Python wrapper to run single ROC and module tests using a DTB.

dependencies:

• python2.7
• cython (http://cython.org/)
• numpy (http://www.numpy.org)
• pyROOT (http://root.cern.ch/drupal/content/pyroot)
• pxarCore (compile pxar using cmake -DBUILD_python=ON .. && make install)

usage:

To start pyxar, make sure to set the library paths, and run:

./pyXar

Specify the input directory with:

./pyXar --dir PATH

implementing a test:

All tests inherit from the base class Test in test.py For a test to be included in the fraework the new class must be importet in the

python/__init__.py

file under pyhton

tests usually contains at least the method run()

Two additional methods prepare() and cleanup() give the usual structure of a test.

• The base class provides all necessary obejcts like tb and dut.
• DAC parameters changed during the test will be automatically reset.
• The docstring of the class is displayed as help message in the command line interface.

Prepare the pxarCore library:

Get pxar from its github repositoryand build it

mkdir build
cmake -DBUILD_python=ON ..
make install

Export the path to the library:

export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:PATH/TO/API/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:PATH/TO/API/lib
export PYTHONPATH=$PYTHONPATH:PATH/TO/API/lib

or use the pyXar.sh script which assumes pxar is installed along the pyxar directory.

To start pyxar using the API, run:

./pyXar --api
