About Setting Up CCX
Click Analysis > Clearance and Creepage Analysis to open the Clearance and Creepage Analysis dialog box and then click Menu > Options.
Clearance and Creepage Extension creates the ccx_config.ccx file in the working directory. This file stores the settings. Copy this file to the folder of another part to apply the settings to the other part.
Option Name
Description
CTI parameter name
Name of the parameter for the CTI values of parts or part surfaces.
Default CTI value
Default CTI value for unassigned parts.
Default violation tolerance
Value added to the distance for clearance and creepage.
Unit
Unit to use for the display of length and distance. Valid values are mm and inch.
Decimal places
The number of decimal places for the values specified as the distance parameters. The default values are 2 mm and 4 inches.
Number of cores
Number of cores you are using for computation on a machine. It is recommended to set the value to the maximum number of available cores. If you want to run other programs while performing the CCX analysis, you can reduce the number of cores.
Clearance sampling distance
Defines the distance between the discrete samples in the distance field around a source net. Clearance sampling distance and Creepage sampling distance are a trade-off between parameters for speed and accuracy. The maximum error of a resultant path is approximately one-tenth of the specified sampling distance. The default value large assemblies for both measures is 0.4 mm. For smaller assemblies, the sampling distance can decrease with little impact on the computation time.
Creepage sampling distance
Violation if Path <= Violation Distance
Flags a path as a major violation when the path distance is less than or equal to the violation distance.
Violation if Path < Violation Distance
Flags a path as a major violation when the path distance is less than the violation distance. If the path distance is equal to the violation distance, it is flagged as a minor violation.
