Abstract
The application discloses a kind of impedance test file generation methods, comprising the following steps: S1: Genesis software retrieves ERP file and TGZ file from database;The impedance information of PCB board is contained in the ERP file, and the layer information of PCB board is contained in the TGZ file;S2: Genesis software identifies ground point according to TGZ file;S3: Genesis software identifies single-ended impedance line and differential impedance line according to ERP file, and calculates its length;S4: the coordinates of the single-ended impedance line and the end point coordinate of ground point in the preset range are positioned, and the two end point coordinates of differential impedance line in the preset range are positioned;Single-ended impedance line, differential impedance line and corresponding coordinates are formed CSV file output;S5: CSV file is decoded as DIF file and is output.The impedance test file generation method provided by the application can automatically output ground point and impedance line, and can output all data at a time, to ensure that impedance test file can be quickly and effectively generated.
