Patent number: 7966588Abstract: A user may optimize a circuit design using a control presented within an Internet browser. The user can change the optimization value of the circuit that in turn places more or less emphasis on a parameter (e.g. foot print vs. efficiency). Once optimized for the values, the list of components matching the design as well as the optimization operating values are presented to the user.Type: GrantFiled: January 26, 2008Date of Patent: June 21, 2011Assignee: National Semiconductor CorporationInventors: Jeffrey Robert Perry, Malcolm Humphrey, Mark Davidson, Dien Mac, Denislav D.
