ERF Variables for Testpoint Analysis

Variables set in the ERF file control the analysis.

Variable	Description	Categories Affected
process_map_layer_bot	Process map layer for bottom side of board	All categories classified by area
process_map_layer_top	Process map layer for top side of board	All categories classified by area
v_exposed_tp	The edge of a testpoint from which to measure. 1 — (default) Measures only from the exposed edge. 0 — Measures from the edge, whether exposed or not.	Testpoint to Testpoint Testpoint to Exposed Copper
v_ignore_tp2c_same_net	Controls whether violations between testpoints and exposed copper on the same net are reported. 0 — Reports all violations (default) 1 — Does not report violations between testpoints and exposed copper of the same net. This ERF variable remains to maintain backward compatibility. It is overridden by v_report_same_net_spacing.	Testpoint to Exposed Copper
v_report_same_net_spacing	Controls whether to report all testpoint to copper violations together or only those of different nets. yes — Report spacing violations between testpoints and copper features regardless of net. no — Only report spacing violations between testpoints and copper features of different nets. This variable, when set to no, takes precedence over v_ignore_tp2c_same_net.	Testpoint to Exposed Copper
v_sub_cat_default	Indicates the attribute used in component classification. Empty — If left empty, the system searches for User Type, if at least one package has a user type designation. Otherwise, it searches for Package Type. If not found, no classification according to component type is performed. (default) Package Type — Component classification types assigned prior to import. User Type — User-defined component classification types assigned prior to import. String — Any string identical to the desired component attribute name. Mount Type — The mount type used by the component. [Possible values: SMT; THMT; PRESSFIT or Other]	All categories classified by component type
v_testpoint_attr	Determines the attribute used for testpoint designation of a pad. ICT Test Point — Accepted as a testpoint. Test Point Potential — If its value is potential_tp_manually or potential_tp_by_analysis, accepted as a testpoint. both — At least one of the above attributes is accepted as a testpoint. A pad with contradictory attributes (ICT Test Point and Test Point Potential = not_potential_tp_manual) is not accepted as a testpoint.	All categories
v_tp2c_by_side	Determines whether all testpoint to exposed copper measurements are reported to ‘Testpoint to Exposed Copper’ or according to the side found. no — Reports all violations to ‘Testpoint to Exposed Copper’. yes — Reports violations to ‘Testpoint to Exposed Copper (Primary)’ or ‘Testpoint to Exposed Copper (Secondary)’.	Testpoint to Exposed Copper
v_tp2tp_by_side	Determines how results are reported for measurements between testpoints. no — Reports all results to ‘Testpoint to Testpoint’ category. (default) yes — Reports results to ‘Testpoint to Testpoint (Primary)’ or ‘Testpoint to Testpoint (Secondary)’.	Testpoint to Testpoint
v_tp_density_box_size	Determines the length of a side for the square area containing the testpoints.	Testpoint Density
v_tp_density_number	Determines the number of testpoints within an area to be reported.	Testpoint Density
