Development and Analysis of Electronic and Electrical Experiment Simulation Technology
Bibliographic record
Abstract
Abstract The development of electronic and electrical technology is based on the tedious experiment of electronic and electrical engineering, which is operated by electronic working platform. EWB (electronic workbench) is a kind of electronic circuit simulation software developed by Canadian interactive image technology company in 1988. The software design function is perfect, the operation interface is friendly, the image is very easy to master. The software core of EWB is Spice3f5, which enhances its simulation ability in digital and analog mixed signals. The development of EWB not only solves the problem of time-consuming, laborious and expensive in electronic circuit design, but also brings great convenience and benefits to electronic product designers. They can use computer-aided design to carry out circuit simulation, which can effectively save development time and cost. Only through continuous experiments can we verify the reliability of the circuit and improve the circuit design, but in the specific experimental operation, some factors often lead to the failure of the experiment, which not only increases the cost of the electronic and electrical experiment, but also destroys the original equipment, and also has certain risks. Therefore, to solve this problem, the simulation technology has been widely used in the electronic and electrical experiment. Moreover, the convenient operation mode of EWB, the intuitive circuit diagram and the display form of simulation analysis results are also very suitable for the auxiliary teaching of electronic course, which is conducive to improving students' understanding and mastery of theoretical knowledge and cultivating students' innovation ability. Therefore, many universities in the world have brought EWB into the teaching of electronic courses. This paper mainly describes the application value and specific application mode of simulation technology in electronic and electrical experiment, in order to further expand the application scope of simulation technology in electronic and electrical experiment. The component library of EWB provides thousands of circuit components, including passive components and active components, analog components and digital components, discrete components and integrated components, as well as new or expanded existing component libraries. EWB also provides a complete set of virtual instruments, such as oscilloscope, signal generator, multimeter, baud chart instrument, spectrum analyzer and logic analyzer. Using these components and instruments to simulate electronic circuits is just like doing experiments in a laboratory. It is very real. Moreover, it is not necessary to worry about damaging the instruments and components, or to be at a loss for outdated instruments and insufficient measurement accuracy. This paper first analyzes the advantages of simulation technology in the application of electronic and electrical experiment teaching, and then analyzes the experimental means and application practice of simulation technology in detail[1].

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
