Method for assigning power and ground pins in array packages to enhance next level routing

摘要

A method for assigning power and ground pins in array packages in order to enhance next level routing is provided. In one embodiment, the method comprises arranging connections of a semiconductor array package, the semiconductor package having an integrated circuit with power, ground, and signal connections, in 23 connection grids. Each connection grid includes a power connection and a ground connection which is adjacent to the power connection. The 23 connection grids are arranged so that each connection at the periphery is a signal connection. A 4:1:1 signal:power:ground connection ratio is maintained in the arrangement, wherein no more than four signal connections are present for each power connection, and no more than four signal connections are present for each ground connection.
