COP: a Crosstalk OPtimizer for gridded channel routing

Abstract: The interwire spacing in a VLSI chip becomes closer as the VLSI fabrication technology rapidly evolves. Accordingly, it becomes important to consider crosstalk caused by the coupling capacitance between adjacent wires in the layout design for the fast and safe VLSI circuits. The upper bounds of the allowable crosstalk for nets, called crosstalk constraints, are usually given in the design specification. This paper proposes a crosstalk minimization technique based on segment rearrangement for gridded channel ro… Show more

“…To copy otherwise, or republish, to post on servers or to redistribute to lists, requires prior specific permission and/or a fee. Because of this lack of flexibility, it is important that crosstalk be handled not just as a post-processing step, as it is in [5,9], or during detailed routing, as it is in [2,3,6,7,8]. If an FPGA router can only optimize for crosstalk during detailed routing, the limited switch and connection block flexibilities make it unlikely that any optimizations will be possible.…”

“…Channel and switchbox routing are used to simplify route topology while satisfying crosstalk constraints [4,5,21, but these rigid routing approaches have limited applicability in modem design methodologies. Other approaches attempt to dictate a detailed routing through assignment or adjustment of physical adjacency [ 1,3].…”

“…This methodology is incapable of rerouting, so is limited to local improvements. The second approach involves routing while minimizing coupling capacitance [4,5,71. Limited by the complexity of detailed routing, this approach is forced to compromise on the quality of crosstalk analysis.…”

“…Until recently, there has been little research on the coupling problem in routing. Coupling reduction was considered at the detailed routing stage for the river routing problem [9], the channel routing problem [10], and the switch box routing problem [11]. Also, there have been efforts in reducing coupling in the stage between global and detailed routing.…”
