Qorvo releases new circuit simulation software for power and analog designers

Qorvo Inc of Greensboro, NC, USA (which provides core technologies and RF solutions for mobile, infrastructure and defense applications) has released QSPICE, a new generation of circuit simulation software that is said to provide power and analog designers significantly higher levels of design productivity through improved simulation speed, functionality and reliability.

In addition to advancing the state of the art in analog simulation technology, QSPICE allows designers to simulate complex digital circuits and algorithms. Its combination of modern schematic capture and fast mixed-mode simulation make it suitable for solving the increasingly complex hardware and software challenges faced by system designers, adds the firm.

“QSPICE enables an entirely new generation of mixed-mode circuit simulation,” says 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,” he claims.

Available free of charge, QSPICE offers enhancements over legacy analog modeling tools including:

  • 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 run-times and a 100% completion rate, based on Qorvo benchmark tests with a suite of challenging test circuits. This compares with 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.

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