  • Distributed electronic design automation environment
    Patent number: 7546571
    Abstract: PCB Logical design data is stored in a database according to a connectivity-based data model. Circuit functional blocks, inputs and outputs of functional blocks, and signals are stored as separate data structures. Those structures may be edited by users at separate clients during concurrent editing sessions. Profile data for each of multiple users specifies logical design data elements accessible by, and PCB design software to be provided to, that user. The PCB design software may be plug-ins executable within a web browser at a client, and the client computers may communicate with the database via the Internet. Layout data may also be stored in the database, with elements of the layout data mapped to elements of the logical design data. Constraint data may also be stored in the database, with elements of the constraint data being mapped to elements of the layout data.

  • Electronic circuit design system and method with programmable addition and manipulation of logic elements surrounding terminals
    Patent number: 5625567
    Abstract: A system and method for programmatically adding pads and ports and altering design logic at the terminals of electronic circuit designs is provided. In a preferred embodiment the system and method are implemented within a system that partitions arbitrary designs but the system and method may be used by itself to add terminal logic. Patterns and connections of removable logic of the internal circuitry can be specified by a user or by system default settings stored in an external file.
