QSPICE

What QSPICE is

QSPICE is circuit simulation software from Qorvo for engineers developing designs from early concepts through final validation. It is a downloadable Windows program that runs locally on the user’s computer. It supports analog systems as well as complex digital circuits and algorithms, and includes schematic capture, advanced electrical simulation, and C++ and Verilog compilers.

Qorvo describes QSPICE as offering high-performance simulation, with frequent updates to its features, capabilities, and accuracy. Users can create MOSFET, diode, and JFET models, and the software has a regularly updated model library featuring Qorvo silicon carbide and advanced power management solutions. Qorvo also lists publication-quality graphics as a benefit. The software is free for commercial use and has no free trial. Its Windows plan calls for Windows 10 (64-bit) or Windows 11, at least 4 GB of RAM, 100 MB of installation space, and at least 16 GB for simulation data. Qorvo provides a QuickStart guide, beginner tutorial, advanced videos, and technical, application, and customer support. Its history says it was formed on January 2, 2015, following a merger of RFMD and TriQuint Semiconductor.

Who it suits

QSPICE suits engineers who need to simulate analog and complex digital circuits on a Windows computer, from concept work through validation. It may also suit users who want C++ and Verilog compilers, model creation, and Qorvo-focused library content.

Limits

The free plan is for Windows 10 (64-bit) or Windows 11 and requires at least 4 GB RAM, 100 MB installation space, and 16 GB for simulation data. There is no free trial.

Getting started

1. Visit Qorvo’s QSPICE page.
2. Use a computer running Windows 10 (64-bit) or Windows 11.
3. Ensure the computer has at least 4 GB of RAM and 100 MB of installation space.
4. Allow at least 16 GB for simulation data.
5. Use Qorvo’s QuickStart guide, beginner tutorial, or advanced videos to learn the software.

Verdict

Choose QSPICE if you need locally run circuit simulation with analog and digital support, compilers, and a Qorvo model library at no cost. Look elsewhere if you need a non-Windows platform or cannot meet its listed storage and memory requirements.
