A system may include a database configured to store information including characteristics of a plurality of components. The system may further include a server in communication with the database and configured to receive design requirements indicative of desired power supply designs; query the database for components that satisfy the design requirements; determine a plurality of power supply designs in accordance with the components and the design parameters; determine key parameters of at least a subset of the determined power supply designs; and rank the power supply designs.

Visualization of tradeoffs between circuit designs

A system may include a database configured to store information including characteristics of a plurality of components. The system may further include a server in communication with the database and configured to receive design parameters indicative of a plurality of loads of a multiple-load device; determine a plurality of power supply architectures that may be used to provide power supply solutions satisfying the plurality of loads, each power supply architecture including at least one position requiring a component configured to satisfy a load requirement; for each one of at least a subset of the plurality of power supply architectures, determine, based on the characteristics of the plurality of components, at least one component configured to satisfy the corresponding load requirement for each position of the one of the power supply architectures; and generate at least one power supply design in accordance with the power supply architectures and the determined components.

A system may include a database configured to store information including characteristics of a plurality of components. The system may further include a server in communication with the database and configured to: receive design parameters indicative of a plurality of power supply loads to be powered; determine a plurality of power supply architectures that may be used to provide power supply solutions satisfying the plurality of loads, each power supply architecture including at least one position requiring a component configured to satisfy a load requirement; for each one of at least a subset of the plurality of power supply architectures, determine, based on the characteristics of the plurality of components, at least one component configured to satisfy the corresponding load requirement for each position of the one of the power supply architectures; and generate at least one power supply design in accordance with the power supply architectures and the determined components.

Power supply architecture system designer

The present invention enables a user to create, modify, simulate and save an electrical circuit using an Internet browser over an Internet connection. The user can change the connectivity of the circuit as well as add and/or remove components in a free form manner. The schematic is displayed within a web page on the user's machine with which the user may interact. Block symbols may be used to represent at least a portion of the schematic.

Method for creating, modifying, and simulating electrical circuits over the internet

A method and apparatus for thermally simulating a circuit over a network is provided. Techniques are provided for designing a circuit that satisfies user-specified functional requirements received over a network. Based on the specified requirements, components and a topology for constructing the circuit are automatically determined. The components determined during this operation have operational values such that, when the components are arranged according to the topology to form the circuit, the circuit satisfies the user-specified functional requirements. One or more web pages that identify the components are then delivered to the browser over the network. The component and topology information may be used to generate a schematic diagram that is delivered in a web page to the user over the network. The user may thermally simulate the designed circuit. Many characteristics of the board may be adjusted to provide an accurate thermal simulation. The user may place an order over the network for one of the components, a kit of all of the components, a custom made circuit made from the components, and/or a prefabricated circuit that is functionally similar to the one that was designed.

Method to perform thermal simulation of an electronic circuit on a network

Techniques are provided for designing a circuit that satisfies user-specified functional requirements without the user having to obtain additional education or possess specialized software. According to one embodiment, user-specified functional requirements are received over a network from a client executing a browser. The network may be, for example, the Internet. Based on the user-specified requirements, components and a topology for constructing the circuit are automatically determined. The components determined during this operation have operational values such that, when the components are arranged according to the topology to form the circuit, the circuit satisfies the user-specified functional requirements. One or more web pages that identify the components are then delivered to the browser over the network. According to one aspect of the invention, the component and topology information is used to generate a schematic diagram that is delivered in a web page to the user over the network. According to another aspect of the invention, the user is provided with a web page that has a control which, when selected, initiates an operation for placing an order over said network for one of the components, a kit of all of the components, a custom made circuit made from the components, and/or a prefabricated circuit that is functionally similar to the one that was designed.

Network-based integrated device identification and ordering system

A method and apparatus for PCB layout of a circuit simulated over a network is provided. Techniques are provided for designing a circuit that satisfies user-specified functional requirements received over a network. Based on the specified requirements, components and a topology for constructing the circuit are automatically determined. The components determined during this operation have operational values such that, when the components are arranged according to the topology to form the circuit, the circuit satisfies the user-specified functional requirements. The components are placed on a PC board having landing areas designed to accommodate all of the anticipated component sizes for the type of circuit being designed. The PC board may be cropped to the desired size. The PCB may be cropped automatically or manually by the user. The component and topology information may be used to generate a schematic diagram that is delivered in a web page to the user over the network. The user may thermally and electrically simulate the designed circuit. Many characteristics of the PC board may be adjusted to produce an accurate circuit.
