Electronic circuit simulation technology is one of the technologies that must be mastered by relevant professional learners and workers today. With the continuous development of electronic circuit simulation technology, many companies have introduced various advanced and powerful simulation software. Since they can contend for a hundred, then there must be advantages and disadvantages in some aspects. The following is a comparison of the advantages and disadvantages of several mainstream electronic circuit simulation software.
Advantages of electronic circuit simulation technology1. Electronic circuit simulation software generally has a large and complete electronic component library and advanced virtual instruments and instruments, which is very convenient for simulation and testing;
2, the connection of the simulation circuit is simple and fast, no need to weld, use the instrument to debug without worrying about damage; greatly reduce the design time and money cost;
3, electronic circuit simulation software can perform a variety of accurate and complex circuit analysis.
1, MulTIsim
In the virtual simulation of complex circuits of analog and digital, MulTIsim is a well-deserved brother. It has a highly realistic virtual instrument that is visualized, and the highest level is achieved regardless of the appearance of the interface or the inherent function. It has a professional interface and classification, powerful and complex functions, and extremely accurate calculation of data. When we participated in the e-sports, especially in the direction of simulation, the simulation software we used the most was MulTIsim. At the same time, MulTIsim not only supports MCU, but also supports assembly language and C language for MCU injection program, and has its associated plate-making software NI Ultiboard10, which can be used for one-stop service from circuit design to board layout.
The disadvantage of Multisim is that the software is too large, the support for the MCU is insufficient, and additional functions such as board making are not comparable to other specialized software.
2, Tina
Tina's interface is simple and intuitive, the components are not too many, but the classification is very good, and TI's components are the most complete. TI's components are often used during the game. When Multisim can't find the corresponding device, we will use Tina to simulate.
The disadvantage of Tina is that it has relatively few functions and supports less components outside of TI.
3, Proteus
As a software integrating circuit simulation, PCB design and single-chip simulation, Proteus not only contains a large number of real-world-based components, but also supports many mainstream MCU models and general peripheral models, and also provides the best real-time display effects. Its dynamic simulation is based on frames and animations, thus providing a better visual effect. Proteus supports editing/compilation/source level emulation of MCU assembly language, assembly compiler with 8051, AVR, PIC, and can also be combined with third-party integrated compilation environment (such as IAR, Keil and Hitech) for high-level language source code level. Simulation and debugging.
The disadvantage of Proteus is that it lacks data calculations for the circuit.
4, Cadence
Cadence acquires and integrates Pspice's capabilities to cover the entire process of electronic design, including system level design, functional verification, IC synthesis and place and route, analog, mixed-signal and RF IC design, full custom IC design, IC physical verification, PCB design and hardware simulation modeling. Cadence is the first choice for complex EDA designs.
The disadvantage of Cadence is that the operation is more complicated and more suitable for the development of complex boards.
5, Matlab simulation toolkit Simulink
At present, Matlab, a large scientific computing and simulation software, has been equipped with a power system toolkit, which allows Matlab to be used for power electronics simulation. PowerSystem's simulation is based on Matlab's Simuilnk graphics environment, so it is as easy to use as PSpiee. Simulink is one of the most important functional modules in the Matlab software package. It is an interactive, modular modeling and simulation dynamic analysis system. In the field of power electronics, Simulink is usually used to build a simplified model of power electronics (such as the fundamental frequency model) and connected into a system to directly design and simulate the controller. Simulink provides excellent support for C code, and can work in both interactive graphics and batch mode in Matlab command language mode.
Matlab is a simulation tool based on idealized power components and functional modules. Matlab's powerful mathematical functions make PowerSystem's control functions very good, especially with other related toolkits, the circuit can achieve extremely fine control without much effort. Another advantage of using Matlab is that its data processing is very efficient and detailed, and its running speed is fast; its format compatibility is very good, it is convenient for post-processing and analysis of data, especially the research and analysis of control characteristics.
The shortcoming of Matlab is that the current PowerSystem is based on the model of general circuit components and mathematical modules (such as transfer functions) to simulate, and the parameters of the actual components are different, the simulation results have a certain distance from the actual circuit, the reference significance of the results Mainly reflected in the overall system and system. Among them, the switch and the control unit use a large number of ideal components, and the switch controller can be directly connected to the switch without considering the level shift. The transient process description of the actual switch is basically ignored. In summary, Matlab is a simulation of an ideal model and cannot be considered in an irrational state.
6, Altium Designer
In addition to fully inheriting the features and benefits of previous versions including Protel 99SE and Protel DXP, Altium Designer adds many improvements and many high-end features. The platform broadens the traditional interface for board-level design and fully integrates FPGA design functions and SOPC design implementation capabilities, allowing engineers to integrate FPGAs in system design with PCB design and embedded design.
Altium Designer is mainly used for schematic design, circuit simulation, PCB drawing editing, and is also a must-have software for the game.
The downside of Altium Designer is that the design of complex boards is not as good as Cadence.
Old-fashioned Bluetooth Speaker
For Old-fashioned Bluetooth Speaker, I personally think that when many people buy Vintage speakers, the appearance is the first priority and the function is second.
We focus on retro Bluetooth speakers,It has high energy density, mini size, light weight and diversified shapes;Excellent fast charging performance, support fast charging and other excellent features with a brand-new design, showing retro nostalgia without losing fashion. It uses a 2.5-inch speaker and has many functions such as FM radio, Bluetooth fast connection, multi-mode switching, and HIFI high fidelity. Wireless Bluetooth 4-10 hours of playback (at 50% volume), which adds to its unique charm.
The sound quality of small speakers is also good. It does not have the same large speakers and power as HIFI speakers, and its sound quality cannot compete with large speakers due to physical limitations. But for the vast majority of users who are not golden ears, the use of small speakers with tablets and mobile phones is sufficient to meet their hearing requirment.
