Part Type
1. Open 13_amp_plug.asm.
2. Click Analysis > Clearance and Creepage. The Clearance and Creepage dialog box opens.
3. CCX allows you to assign special types to conductive parts such as Rivet, Screw, and Spring to make the analysis more robust. These types can be selected via a drop-down list.
The following special types are currently available:
Rivet: If a part is a rivet, CCX automatically determines the insulations which are directly pressed together by the rivet and does not allow a creepage and clearance path to go through the respective connection.
Spring: If a part is a spring, CCX replaces the geometry of the spring by a cylinder internally. This represents all the possible positions with respect to a rotation around the spring’s main axis.
This makes the analysis more robust.
Screw: Similar to Spring, CCX replaces the geometry of screws by the hull internally. This represents all the rotations around the main axis to make the analysis more robust.
4. Click Proceed to Analysis. The Clearance and Creepage dialog box opens. It contains the UI elements to define electric nets and set analysis parameters. The following image and table describes the UI options:
UI Element
Description
Net Name
List of all the nets.
Net Type
Select the type of net from the following:
Potential
Grounded
Potential-free
Merge Nets
Combines individual nets into a common net.
Reset Nets
Resets the entire list of nets to the default state.
Auto Merge Nets
Specify a proximity threshold in the Auto merge distance. Click Auto Merge Nets to apply the threshold.
Source
Select a net of type Potential as the source from the Source dropdown list.
Target Net
After a source is selected, the potential target nets are automatically listed under Target Net.
Compute All
Performs an analysis of all possible sources, independent of the currently selected source.
Compute Current Source
Performs the clearance and creepage analysis only for the currently selected source.
