It’s important to note that QSPICE was built from the ground up—a rewrite of the SPICE code—to include better SPICE basics. One of the key differentiators is that it offers mixed-signal simulation. It supports a massive amount of digital circuit networks—a paramount advancement for SPICE simulators. The inclusion of digital was done with the power engineer in mind – to provide them with the ability to simulate circuits and systems that combine RF that can handle high-power levels while preserving RF performance, efficiency and reliability.
Users can write C++ or Verilog source code into native object code, which enables faster and more efficient execution of the simulation, potentially allowing for larger and more complex simulations to be performed within reasonable timeframes.

It has a more modern GUI that is very intuitive and offers a graphical circuit view, allowing users to easily create and edit circuits.

QSPICE offers numerous enhancements over legacy analog modeling tools. These improvements include:
• Complete support for advanced analog and digital system simulations, such as those used in AI and machine-learning applications.
• An upgraded simulation engine that uses advanced numerical methods and is optimized for modern computing hardware, including a GPU-rendered user interface and SSD-aware memory management, to provide dramatically higher speed and accuracy.
• Reduced overall runtimes and a 100% completion rate, based on Qorvo benchmark tests with a suite of challenging test circuits. This compares to a failure rate of up to 15% with these same test circuits using other popular SPICE simulators.
• Availability of a regularly updated QSPICE model library featuring Qorvo’s silicon carbide and advanced power management solutions, making it easy for customers to evaluate and design with Qorvo power.
