Variant Definitions in CSV Files

Variant or Part Definition CSV files contain the properties that are present in the Allegro component definition. In addition, the import process adds some mandatory properties that facilitate the mapping between the schematic symbol and the footprint view. These properties are footprintLibNames, footprintCellName, footprintViewName, and altFootprintCellNames. The mapping process goes through the libraries specified in the footprintLibNames property and tries to find the cell and view described by the footprintCellName and footprintViewName properties. The first cellview that is found is used as the footprint cell when the layout is generated for a schematic that contains an instance of the generic schematic symbol.

You can import the Part Definition CSV using the Part Data form, which displays information from a part.csv file for the selected library or cell. Each row in the Part Data form corresponds to a row in the part.csv file. The first row is the filter row using which you can filter the available parts based on specific criteria. For example, if you want to view only those parts of the Pack_Type is 01005, you can type 01005 in the filter column for Pack_Type. You can also sort the data in the form by clicking on the header of a particular column.
