Abstract
Tile-based routing between a bump pad and an input/output (I/O) device for implementation on a flip-chip integrated circuit (IC) die. A trace is routed between the bump pad and a position corresponding to a first I/O slot, the first I/O slot being at least partially occupied by the I/O device. A position is obtained for a device pad for the I/O device. The trace is then extended into an area corresponding to the position obtained for the device pad. It is a feature of this aspect of the invention that the trace extension extends the trace into a pad area for a second I/O slot, the second I/O slot being at least partially occupied by the I/O device. The invention also concerns a flip-chip integrated circuit (IC) die that includes a bump pad, an input/output (I/O) device, and a device pad electrically connected to the I/O device and disposed vertically adjacent to a portion of the I/O device. Also provided is an electrically conductive trace, including a first portion between the bump pad and a first position, the first position corresponding to a portion of the I/O device and being horizontally offset from the device pad, and also including a second portion between the first position and a second position corresponding to the device pad.
