Abstract: 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 said second region.

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.

Abstract: An electrical resistance determination method. Input to the method includes a description of at least one electrical network within a substrate. The description includes specification of a plurality of first ports on a first side of the substrate, and a plurality of second ports on a second side of the substrate, for each electrical network. All of the first ports are electrically isolated from one another. All of the second ports are electrically connected to a common voltage. A computer readable program code, which is executed by a processor of a computer system computes for a first electrical network of the at least one electrical network an electrical resistance between each first port and a port of the second ports. The computer code may also display a perspective plot of the computed electrical resistances as a bar oriented about normal to each first port.

Abstract: Disclosed is an improved method of determining mutual inductance of wires in an electronic design. First, the invention selects a pair of wires. Then, the invention adds concentric ring lines to the design. The invention then adds straight line segments representing each wire between points where each corresponding wire crosses the adjacent ring lines. Each of the straight lines run from a point where a corresponding wire crosses an outer concentric ring line to a point where the corresponding wire crosses an inner concentric ring line. The invention can then very simply calculate the mutual inductance between the straight line segments (not the actual potentially non-linear wires themselves). The mutual inductance of the straight line segments only comprises an approximate mutual inductance of the wires because the actual mutual inductance of the wires may be slightly different if the wires are non-linear.

Abstract: An automated method of selecting differential pairs in an integrated circuit comprising loading the design database for the integrated circuit package, and selecting output parameters for the differential pairs comprises adjacency criteria for the different pairs, time of flight tolerances for the differential pairs, and the redistribution layers and their voltage references. The method then includes comparing the output parameters to the design in the design database, and obtaining a resulting differential pairs list. The differential pair list preferably includes differential signal pairs having electrical characteristics within a predetermined design tolerance range. At least some of the differential signal pairs may comprise individual wires or connectors not physically adjacent one another.
