What is Virtuoso layout editor?

The enhanced Virtuoso Layout Suite offers accelerated performance and productivity from advanced full custom polygon editing (L) through more flexible schematic-driven and constraint-driven assisted full custom layout (XL), to full custom layout automation (GXL).

What is Cadence schematic?

The Cadence® Virtuoso® Schematic Editor provides numerous capabilities to facilitate fast and easy design entry, including design assistants that speed common tasks by as much as 5X. Well-defined component libraries allow faster design at both the gate and transistor levels.

How do I open LSW cadence?

The LSW window will show all the layers like nwell, pwell, active etc. for the given process. An alternate way to open the layout editor window, click on “Layout” in the View window for inverter cell in the Library manager window. Then click on File –> Open.

What is OD in cadence?

OD means diffusion layer in Layout. If OD layer is in Nwell then it becomes a PMOS device and if the OD layer is in Pwell then it becomes a NMOS device (it may be different based on PDK). Essentially OD defines the place where you can drop a contact to the well on which it is placed.

What is Cadence VXL?

Part of the Cadence® Virtuoso® Layout Suite family of products, Virtuoso Layout Suite XL is a connectivity- and constraint-driven layout environment built on common design intent. It supports custom analog, digital, RF, and mixed-signal designs at the device, cell, block, and chip level.

Which is the schematic and layout editor software from Cadence?

In the Virtuoso® Schematic Editor course, you learn to create and edit schematics for use with the suite of Cadence® simulation and layout tools.

How do you open the layer of a selection window in cadence?

Enter inv as the Cell Name, choose Layout as the Type and Layout GXL. The View Name will be automatically set to layout. Two design windows (Virtuoso and LSW) will pop-up. The Layer Selection window (LSW) (small window on the left in the figure below) lets the user select different layers of the mask layout.
