Described herein is an electronics circuit board design tool. The tool includes a substantially planar non-conductive substrate adapted to be positioned on an electronics breadboard. The substrate includes a plurality of guide apertures at locations corresponding to predefined electrical inputs of the breadboard such that electronic components are able to be connected to the electronics breadboard through respective ones of the guide apertures. The tool also includes indicia printed on a surface of substrate. The indicia is indicative of the type or position of electrical connections or components to be connected with the breadboard through corresponding ones of the guide apertures.

This invention relates to electric circuit simulation means, namely, an electrical circuit simulation technique, its implementation system and simulating component, and may be used in educational activities as a training aid, playing construction kit, breadboard, or test bench for teaching circuit engineering.

An electrical circuit simulation technique designed to be performed by a computing complex that is electrically coupled to at least one simulating component; the technique consists of the following: providing at least one electromagnetic coupling between at least two simulating components, of which at least one is electrically coupled to the computing complex; establishing a correspondence between each electromagnetically coupled simulating component and simulated electrical circuit element; computer simulation of the simulated electrical circuit consisting of electrical elements corresponding to the coupled simulating components and composed in such a way that an electrical coupling between the electrical circuit elements simulated by the simulating components corresponds to each electromagnetic coupling between the simulating components; reproduction of the results of computer simulation of the simulated circuit to the user.

A method is disclosed to ensure that components in a complex system are correctly connected together. In one embodiment, such a method provides a library of previous configurations of a system. The system includes multiple components connected together with cables. The method generates, from the library, instructions for assembling the system by connecting components of the system together with cables. The method receives feedback generated in the course of using the instructions to assemble the system and uses the feedback to refine the instructions. In certain embodiments, a configuration associated with the assembled system is then added to the library. This process may be repeated to further refine the instructions and increase a number of configurations in the library. A corresponding apparatus and computer program product are also disclosed.

A system of interconnecting trainers is provided. The trainers may share power and/or exchange control signals, resulting in reduction in weight/size and increase in portability. Some of the trainers may include a rechargeable battery to allow the trainers to operate without being connected to an AC outlet. A power source selector switch may select an external AC power source or the internal battery to be used by the trainer. Some the trainers may include one or more DC and/or AC signal distribution relays that may receive control signals from student designed circuits or controllers and may provide DC and/or AC signals to other trainers. Some of the trainers may include built-in devices such as oscilloscopes, signal generators with displays, multimeters, and pneumatic devices.

A high-speed signal subsystem testing system tests a processor transmitter and receiver coupled to a connector via a transmitter trace and a receiver trace, respectively. A transmitter test circuit on a testing board coupled to the connector compares a transmitter voltage received from the transmitter via the transmitter trace and the connector to a common mode voltage range and, in response to the transmitter voltage being outside the common mode voltage range, provides a transmitter trace issue signal. A receiver test circuit on the testing board coupled to the connector transmits a first test voltage towards the receiver, compares a second test voltage detected at the receiver test circuit in response to transmitting the first test voltage towards the receiver to a reference test voltage and, in response to the second test voltage being above the reference test voltage, provides a receiver trace issue signal.
