How to Add or Modify Nets in SI Wave

This guide explains how to add a new net or modify an existing net in SI Wave. Follow the steps below to ensure accurate modifications.

Initial Setup

First, make sure to select the layer where you want to perform the modifications.

Options for Modifying Nets

You have three main options:

1. Add a New Net: Create a net that doesn't belong to any existing net in the circuit. You can create various shapes such as:
   • Circle
   • Rectangle
   • Trace
   The new structure you create will be named net_1, indicating it is a brand new net.
2. Modify an Existing Net: To modify an existing net, use the merge function. Ensure that the new structure overlaps with the existing net. This helps SI Wave recognize that the new modification belongs to the existing net. For example:
   • Click on the areas where the new structure overlaps with the existing net.
   • SI Wave will merge them or recognize them as belonging to the same net.
   Note: In some cases, such as with integrated circuit pads, SI Wave might not merge them but will assign the same name, indicating they are considered as one in the simulation.
3. Subtract from a Net: To subtract from a net, simply click on the areas you wish to modify. The process is straightforward and simple.

Additional Notes

In some instances, SI Wave may not merge structures but will still recognize them as part of the same net by assigning the same name. For example, if you click on a ground net and its modification, both will be labeled as "ground," indicating they are considered as one in the simulation.
