QSPICE at APEC 2026: Faster Simulation, Open Licensing, and Real Mixed-Mode Performance

At APEC 2026, Bryan DeLuca from eeVids sat down with Mike Engelhardt, the creator of QSPICE, to discuss what is new with the platform and why engineers may want to take a closer look at it.

A New Take on SPICE Simulation

According to Engelhardt, QSPICE builds on traditional SPICE simulation while improving the overall experience and performance. Even for standard SPICE simulation tasks, he says the tool delivers a better experience than what many engineers may be used to from older platforms.

The goal is simple: give engineers a SPICE tool that works reliably, produces answers quickly, and removes some of the friction that has long been associated with simulation software.

Strong Mixed-Mode Simulation Capability

One of the biggest highlights discussed at APEC 2026 was QSPICE’s mixed-mode simulation capability. Engineers can describe digital logic in C, C++, or Python, compile that code into native Intel object code, and execute it during simulation.

This gives QSPICE the ability to process digital logic at extremely high speed while running alongside analog simulation. For engineers working in power electronics, embedded control, and other mixed-signal applications, that kind of performance can be a major advantage.

Model Generation Tools Help Fill in the Gaps

Another important feature of QSPICE is its built-in model generation tools. Engelhardt explained that the software can help engineers digitize datasheet information and create models for components that may not yet have simulation models available.

That can save valuable development time and make it easier to start simulating real-world parts earlier in the design cycle.

Open Licensing for Broad Use

QSPICE also stands out for its unrestricted licensing model. The tool is free to use and can be adopted for both internal development and commercial applications without limitations.

That kind of open access can make QSPICE especially attractive for companies and engineers looking to avoid the restrictions that can come with other simulation tools.

High-Quality GPU-Based Graphics

QSPICE also puts a strong focus on visualization. The platform delivers publication-quality graphics and leverages GPU acceleration to significantly improve rendering performance compared to traditional CPU-based approaches.

While simulation performance is always the priority, cleaner and faster graphics can improve the overall workflow and make it easier to work through complex designs.

What Is the Biggest Benefit for Engineers?

When asked what design engineers would benefit from most by adopting QSPICE, Engelhardt gave a very direct answer: it simply works.

That may sound straightforward, but it addresses one of the most common complaints engineers have about simulation tools. SPICE platforms can be powerful, but they can also be frustrating, unstable, or slow. QSPICE is designed to reduce those pain points while still delivering fast and meaningful results.

Why It Matters

For engineers designing modern electronic systems, simulation tools need to be fast, dependable, and flexible enough to handle both analog and digital domains. QSPICE is positioned as a next-generation tool that delivers improved speed, accuracy, and the ability to handle large amounts of digital logic without performance penalties.

With improved SPICE fundamentals, powerful mixed-mode simulation, built-in model generation tools, unrestricted licensing, and GPU-accelerated graphics, QSPICE provides a more capable and efficient simulation environment.
