A system and method for generating simulated wiring connections between a semiconductor device and a carrier. The method comprises identifying a plurality of first factors and instances of each first factor relating to the semiconductor device and identifying a plurality of second factors and instances of each second factor relating to the carrier. The first and second factors are associated with each other on a one-to-one basis. A simulated wiring connection is generated between a first I/O terminal and a matching second I/O terminal, subject to an identified instance of each first factor of each first I/O terminal being correlated to an identified instance of the associated second factor of the matching second I/O terminal. A simulated wiring connection is generated between third I/O terminals located in a first region and fourth I/O terminals located in a second region.

Auto connection assignment system and method

A system and method for generating simulated wiring connections between first I/O terminals of a semiconductor device and second I/O terminals of a carrier. The method comprises identifying a plurality of first factors and instances of each first factor relating to a semiconductor device and identifying a plurality of second factors and instances of each second factor relating to a carrier. The first and second factors are associated with each other on a one-to-one basis. The instances of each first factor are correlated to the instances of each associated second factor on a one-to-one basis. A simulated wiring connection automatically is generated between each first I/O terminal and a matching second I/O terminal, subject to an identified instance of each first factor of each first I/O terminal being correlated to an identified instance of the associated second factor of the matching second I/O terminal.

A method for enhancing power bus for I/O libraries in ASIC designs is disclosed. An I/O assignment for I/O circuits to be utilized in an ASIC design is initially generated. Each I/O circuit may obtain power from either a primary I/O power bus or a secondary I/O power bus. A determination is then made as to whether or not the I/O assignment meets certain predetermined power distribution requirements. In a determination that the I/O assignment does not meet the predetermined power bus distribution requirements, a power enhancement cell is added. The power enhancement circuit includes at least one metal line for connecting the primary I/O power bus to the secondary I/O power bus in order for the I/O assignment to meet the power bus distribution requirements.
