What is Cadence Virtuoso XL?

Cadence Virtuoso XL is a layout editor used in the design of integrated circuits (ICs), particularly analog, mixed-signal, and custom digital circuits. It provides a graphical user interface for creating and editing the physical layout of transistors, interconnects, and other components on an integrated circuit. Virtuoso XL is often used in conjunction with other Cadence tools for simulation, verification, and physical implementation.
