Layout Editing
This topic summarizes how to edit the placement of components in the layout and how to add additional components.
- Constraint-Aware Editing - This mode ensures that the Layout XL manual editing commands respect physical constraints that may be set on your design components.
- Moving Objects - Different ways to move an object to another location in the current or another cellview.
- Adding an Instance in Layout - Different ways to the layout an instance that is not present in the schematic.
- Adding a Pin - Steps to add pins to layout.
- Assigning Instance Pins to a Net - Steps to connect a new instance to an existing net in a design that has a connectivity source.
- Transistor Folding - Interactively divide the different types of transistors into two or more layout instances with terminals all connected in parallel to the same nets.
- Pin Permutation - Exchange the connectivity or net connections of the pins of a component.
- Incomplete Nets - Show incomplete electrical connections between the component terminals, pins, and shapes associated with each net in your design.
- Editing In Place - Use the Edit In Place command to edit a placed instance in your design and maintain the connectivity.
- Soft Block Editing - Modify the soft blocks in your design.
- Smart Display - A layout editing environment that can be used to generate a symbolic representation of the layout by using one of the two modes, Abstracted or Schematic.
- Net Name Display - Add net name labels in the layout canvas for shapes that have associated labels. Having the net name labels display in the layout canvas makes layout editing simpler, especially for large designs.
- Composite Waveguides (Virtuoso Photonics Option) - If you are using the Virtuoso Photonics Solution, Layout EXL or higher enables you to use optical connections called waveguides in your design. When several such optical connections or waveguides are used in a design, the resultant waveguide is called a composite waveguide.
