High end networking and computing applications continue to drive silicon technologies to higher data rates, increased storage capacity, and increased bandwidth. Interfaces are transitioning more toward serial technologies, even for short distance data transfer. Voltage supply rails continue to drop and consequently, the noise margins become reduced, even with increasing numbers of simultaneously switched...
Most existing buffer insertion algorithms, such as van Ginneken's algorithm, consider only individual nets. As a result, these algorithms tend to over buffer when applied to combinational circuits, since it is difficult to decide how many buffers to insert in each net. Recently, Sze, et al. (Sze, 2005) proposed a path-based algorithm for buffer insertion in combinational circuits. However their algorithm...
This paper discusses design tradeoffs for high speed signal performance in buildup laminate packages with high wiring density. Trace design in die escaping area, PTH vias placement pattern and BGA I/O assignments are analyzed in depth for design optimization through numerous simulations as major areas of high coupling concern and channel performance. Then design suggestions are made at each area for...
