Introduction

Cadence is one of the most widely used software tools in the electronics industry. It has great features and a user-friendly interface that makes it easy to use by design engineers. One of the most important aspects of designing an electronic circuit is the packaging of the components. The shielding package is one of the most important components in electronic circuits that provides electromagnetic isolation for sensitive electronics components. In this article, we will discuss how to draw a Shielding Package Enclosure (SPE) using Cadence Virtuoso.

Drawing the Shielding Package Enclosure (SPE) using Cadence Virtuoso

Step 1: Create a Rectangle

Firstly, start by opening a new layout window in Cadence Virtuoso. Then select the Rectangle tool from the toolbar and draw a rectangle on the layout. This rectangle will be the outline of the shielding package enclosure.

Step 2: Add Cutouts and Vias

The next step is to add cutouts and vias to the rectangle. These cutouts will create openings in the shielding package. Cutouts and vias are used to anchor and secure the shield to the printed circuit board (PCB). To add a cutout, select the Rectangle tool, draw a rectangle on the rectangle, and then right-click on the rectangle to select \"Cutout\". To add a via, select the Via tool from the toolbar and place it where required. You can also use the Mirror tool to create a copy of the cutout or via and place it on the other side of the rectangle to create symmetry.

Step 3: Complete the Design

The final step is to complete the design. This can be done by creating labels, text or images that will appear on the shielding package. When the design is complete, select the Design Rule Checker (DRC) tool from the toolbar to check the design against the rules and regulations of the project. Finally, select the Generate GDS option from the toolbar to export the design to be used for the manufacturing of the Shielding Package Enclosure (SPE).

Conclusion

Drawing a Shielding Package Enclosure (SPE) using Cadence Virtuoso is an easy task that can be done by anyone. Cadence Virtuoso provides a user-friendly interface and all the tools that are required to create an electronic circuit with the shielding package enclosures. The shielding package enclosures are the most important components of electronic circuits that provide electromagnetic isolation for sensitive electronics components. Correctly designing these components ensures their reliability, safety and the proper functioning of the entire electronic circuit.
