Qorvo has released its QSPICE circuit simulation software with support for digital AI and machine learning frameworks.

QSPICE was previewed to eeNews Power at the PCIM exhibition in May and allows designers to simulate complex digital circuits and algorithms. A combination of modern schematic capture and fast mixed-mode simulation makes it suitable for the increasingly complex hardware and software challenges faced by today’s system designers, including support for AI and ML frameworks.

The tool is available free of charge and has been re-written by SP{ICE pioneer Mike Englehardt to provide enhancements over legacy analog modelling tools.

“QSPICE enables an entirely new generation of mixed-mode circuit simulation,” said Jeff Strang, general manager for Qorvo’s Power Management business. “In the past, power designers relied on analog circuits and silicon power switches. Today, digital control and compound semiconductors are common elements of advanced power designs. Whether an engineer is developing AI algorithms for EV battery charging, optimizing a Qorvo pulsed-radar power supply or evaluating the newest silicon carbide FETs, QSPICE is the perfect platform for innovation.”

QSPICE provides complete support for advanced analog and digital system simulations, such as those used in AI and machine-learning applications. The 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.

The tools shows 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.

A regularly updated QSPICE model library includes Qorvo’s silicon carbide and advanced power management solutions, making it easy for customers to evaluate and design with Qorvo power.

QSPICE is available now at and is actively supported by Qorvo as well as a robust user community through Qorvo’s QSPICE forum at
