The circuit simulation software can also advance analogue simulation technology and allows designers to simulate complex digital circuits and algorithms. It is distinguished, says Qorvo, by its combination of modern schematic capture and fast mixed-mode simulation for complex hardware and software challenges.

According to Jeff Strang, General Manager for Qorvo’s Power Management business, the software “enables an entirely new generation of mixed-mode circuit simulation. In the past, power designers relied on analogue circuits and silicon power switches. Today, digital control and compound semiconductors are common elements of advanced power designs,” he said. The software can be used by an engineer developing AI algorithms for EV battery charging, optimising a Qorvo pulsed radar power supply or evaluating the newest SiC FETs, he said.

QSPICE is available free of charge. Enhancements over legacy analogue modeling tools include support for advanced analogue and digital system simulations, such as those used in AI and machine learning applications.

There is also an upgraded simulation engine that uses numerical methods and is optimised for modern computing hardware, including a GPU-rendered user interface and SSD-aware memory management, to increase speed and accuracy, says the company.

It also features reduced overall runtimes and a 100% completion rate, based on Qorvo benchmark tests with a suite of test circuits. This compares to a failure rate of up to 15% with these same test circuits using other popular SPICE simulators, reports Qorvo.

A regularly updated QSPICE model library featuring Qorvo’s SiC and advanced power management devices is also available.
