A Python script has been written to simplify the tedious task of checking capacitor voltage ratings in design reviews. It works with schematics designed in Altium with the CERN component library.
By parsing the EDIF netlist that is generated from Altium, the script attempts to extract the voltage of each power rail from its name (e.g. P3V3, P12V) - the user can provide the voltages for nets whose name doesn't follow any of the recognized naming conventions.
The output of the script is a table (in text or OpenDocument spreadsheet formats) that juxtaposes the voltage rating of the design's capacitors with their actual voltage applied, easily pointing out if any capacitors of insufficient voltage rating are used.
More details can be found on the project's git repo.
