QSPICE
QSPICE is circuit simulation software for engineers developing designs from an initial concept through final validation.
What QSPICE is
QSPICE is circuit simulation software for engineers developing designs from an initial concept through final validation. It is a downloadable Windows program that runs locally, and it supports analog systems as well as complex digital circuits and algorithms. QSPICE includes C++ and Verilog compilers, schematic capture, and advanced electrical simulation. Qorvo says users can create MOSFET, diode, and JFET models in minutes, and describes the model library as regularly updated with its silicon carbide and advanced power management solutions. The listed benefits also include publication-quality graphics. Qorvo provides a QuickStart guide, beginner tutorial, advanced videos, a technical forum, and technical, application, and customer support. The software is free for commercial use, with no free trial. Its plan requires 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.
