Serious nonsense or real knowledge? See what the large AI model says about power supply simulation
In the past, engineers who participated in power supply-themed exchange activities talked about power supply design tools. I often heard various complaints about emulators, such as
The emulator is easy to run away;
Not easy to converge;
No required model library;
In recent years, various software developers and semiconductor manufacturers have successively launched and iterated multiple emulator tools. Do these problems still exist?
Regarding this question, the editor asked about the universal large model. (Note: The following answers are from Tongyi Qianwen)
A: While power circuit simulation tools meet most design needs, they also have some limitations and shortcomings, including——

In response to the above shortcomings, many software vendors continue to improve product features, add new model libraries, and strengthen integration with other tools to improve the overall simulation effect and user experience.
A: The power supply simulation tool QSPICE has the following possible features and advantages——
QSPICE promises to deliver higher levels of performance than traditional SPICE technology, enabling large-scale circuit simulation and breakthroughs in speed and accuracy, which are critical for modern power supply designs that need to handle large amounts of digital logic and analog mixed signals.
Comment - The statement is basically correct: the upgraded simulation engine uses advanced digital methods and is optimized for modern computing hardware, including a GPU-rendered user interface and SSD-aware storage management, thus significantly improving speed and accuracy.
For complex power management integrated circuits (PMICs) and digitally controlled power converters, QSPICE optimizes digital logic simulation capabilities and can effectively simulate mixed-signal systems including complex digital controllers.
Comment - The statement is basically correct: Compared with other simulators, one of the key differences of QSPICE is that it provides mixed-signal simulation; supporting a large number of digital circuit networks is a major improvement for SPICE simulators; the purpose of adding digital circuits is mainly to consider the power supply What engineers need is to bring them the ability to simulate circuits and systems. These circuits and systems incorporate RF technology to handle high power levels while maintaining RF performance, efficiency and reliability. Complete support for advanced analog and digital system simulation, such as those used in AI and machine learning applications .
Designed specifically for power supply designers, it provides simulation acceleration algorithms and technologies for power conversion, efficiency analysis, transient response, and thermal effects, making the power supply design process more efficient and accurate.
Comments - The statement is basically correct: based on Qorvo benchmarks and a set of challenging test circuits, the overall running time is shortened and a 100% completion rate is achieved. In comparison, if you run the same test circuit using other popular SPICE simulators, the failure rate is as high as 15% . Incidentally, users can also write C++ or Verilog source code into native object code to perform simulations faster and more efficiently, making it possible to perform larger and more complex simulations within a reasonable time frame.
May provide an integrated solution from circuit design, device model library, parameter scanning, optimization to result analysis, allowing users to complete the entire design process on a single platform .
Comment - The statement is basically correct. It is estimated that the data of large models are limited, and the word "possible" is used here to indicate the uncertainty of the view. QSPICE is a design practice service and free system-level design tool provided by Qorvo, which can help complete the design easily and efficiently; some of the tools also include: RF- based interactive tools and calculators (including MatchCalc™), FET-Jet calculation , Modelithics ( Qorvo's GaN model library ) , Keysight model library, etc.
It contains a rich and timely updated component model library, which is especially optimized for new power semiconductors such as GaN and SiC to meet the design needs of high-performance power converters.
Comments - Statement Basically correct: Qorvo provides a regularly updated QSPICE model library, which includes Qorvo's silicon carbide and advanced power management solutions, allowing customers to easily evaluate and design with Qorvo power supplies . The QSPICE update will include models for Qorvo’s new power management solutions. Users can also create their own models and integrate them into the software, or easily import third-party models.
Provides an intuitive graphical user interface to simplify the circuit construction and simulation setup process, while making it easy to view and analyze detailed simulation results.
Comments - The statement is basically correct: QSPICE has a more modern and very intuitive GUI and provides a graphical circuit view, allowing users to easily create and edit circuits.
In addition to the above
"very reliable" comments, the AI large model also provides self-
predictions and deductions
in more dimensions such as "cloud services and collaboration functions", "interdisciplinary simulation capabilities" and "real-time interaction and hardware-in-the-loop testing".
. Due to space limitations and
low relevance to QSPICE, I will not share and comment on them one by one here~
