The unique Simulation Program with Built-in Circuit Emphasis (SPICE) was launched in 1973. Engineer Mike Engelhardt started creating his model of SPICE a quarter-century after its inception. Quick ahead one other 25 years and Qorvo has unveiled QSPICE, the corporate’s newest development in mixed-mode SPICE simulation.
“Mainly, QSPICE is what I would have written 25 years in the past after I wrote LTspice had I identified then what I do know now.” — Mike Engelhardt
In the actual world, many circuits aren’t purely analog or digital. They’re a mixture of each. As an illustration, think about an influence management chip: it might need analog elements for managing voltage and present, but in addition digital elements for controlling the general operation. These are mixed-mode circuits.
Now, conventional SPICE instruments have typically centered on both analog or digital circuits, not each. This is usually a drawback for firms like Qorvo, whose elements are utilized in mixed-mode designs. Common SPICE instruments won’t deal with these combined circuits nicely, resulting in inaccurate simulations or poor efficiency.
That’s the place QSPICE is available in. It’s particularly designed to deal with mixed-mode circuits successfully. It’s like a extra superior model of SPICE that may precisely simulate each analog and digital elements of a circuit, guaranteeing higher efficiency and reliability for engineers working with Qorvo’s elements.

QPSICE stands out as a result of its complete help for mixed-mode simulations. A notable instance is its functionality to simulate Switched-Mode Energy Provides (SMPS) that includes a controller IC written in C++. This demonstrates QSPICE’s proficiency in integrating advanced logic. Earlier than the simulation, QSPICE compiles C++ and Verilog fashions into native code, leading to simulations that run quicker than the precise built-in circuits, in line with Engelhardt. This tight integration additionally permits for the inclusion of great quantities of digital logic inside analog simulations.
Along with its developments in mixed-mode simulation, QSPICE underwent vital re-architecting of its analog evaluation in comparison with Engelhardt’s earlier work. The first goal was to deal with singularities and discontinuities in IV curves. Furthermore, the numerical strategies inherited from the unique Berkeley SPICE have been extensively up to date to leverage fashionable PC architectures.
Regardless of being in Beta standing, QSPICE boasts many options and instruments. As an illustration, it features a complete plotting engine with cursor functionalities. Customers acquainted with Engelhardt’s earlier simulator will discover the schematic editor’s person expertise immediately recognizable. Nevertheless, new customers are inspired to look at a QSPICE quick-start video, as fundamental performance might not be instantly obvious as a result of absence of typical menus or context clues sometimes present in fashionable software program interfaces.
QPSICE, developed by Qorvo, contains fashions for Qorvo’s silicon carbide units and superior energy administration options. It additionally helps third-party fashions, permitting customers to immediately paste “.mannequin” and “.subckt” fashions into the software program. QSPICE’s schematic editor generates acceptable symbols mechanically. It’s a quick, highly effective simulation software, significantly fitted to mixed-mode designs like switch-mode energy provides. Out there for Home windows solely, it’s free for business use however requires registration at QSPICE.com.
