Cadence 3D Design Viewer Enhancements The 3D Viewer has been enhanced in 16.6 to support cavities. Since APD and SiP now support both embedded and open cavities, the viewer has been updated to better visualize cavities. Dielectrics are now represented by opaque layers, and cavities as open spaces. Note: Set the new option Render dielectric layers and specify a value for Transparency in the Options tab of 3D Viewer Design Configuration for the dielectrics to be displayed. If you do not set the option, the cavity will not be displayed. The 3D Viewer now displays the package molding cap. This can be toggled on/off from the Options tab of the 3D Viewer Design Configuration form. You can also set the molding cap height above the soldermask or top substrate layer. The cap outline is drawn the same as the substrate outline by default. To create a more detailed outline, create a PACKAGE_CAP layer on the SUBSTRATE GEOMETRY class and define any mold cap outlines to override the default. In addition, in 16.6 the 3D Viewer: ■ Exports and displays all structures within a clearance value of a particular net. Set the Trim to field to Net and specify a Clearance value in the Options tab of the 3D Viewer Design Configuration dialog box. You can select nets in the canvas or use the Find By Name feature of the Find pane to select multiple nets. ■ Lets you toggle the display of the orientation marker (3D axes). ■ Improved display of complex perforated shapes. In earlier releases, you needed to select the Break up complex shape field in the Options tab of the 3D Viewer Design Configuration dialog box, which is not required anymore. As a result, the field has been removed. Note: To be able to use 3D Viewer from APD (available with L and XL only), you must select the 3D Viewer option in the Cadence Product Choices dialog box. The 3D Viewer option is not available with the SiP Layout XL license, as SiP already includes the appropriate viewer license. This was done to be consistent with all other product options and menu entries. ■ An APD user consuming a 3D Viewer Option license or SiP XL license can release it without exiting the tool by performing a change editor to APD-L. ■ When you choose File – Change Editor in APD and pick a different tool, if the 3D Viewer window is open, it will be closed.
