Wire Width Sizing for Delay and Yield Optimization
ثبت نشده
چکیده
In this paper, two issues about wire width are investigated. The first one is that “Is the minimum wire width under the minimum wire pitch for a process technology good enough from the perspective of timing performance?” The second is that “Is delay sensitive to wire width variation around the optimal width?” We find that the answer to the first issue is “yes”, whereas the answer to the second is “not quite”. Based on the later property, wire width/spacing can be sized to reduce shorts or opens on interconnects so that manufacturing yield can be improved without hampering too much performance.

Interconnect Design Using Convex Optimization
Two wire sizing formulations for optimizing interconnect are presented. The rst minimizes the delay under wire width constraints, while the second minimizes the wiring area under delay and width constraints. A convex programming formulation is proposed, and an e cient algorithm is used to perform the optimization. Experimental results show that the rst formulation, which has been the prevalent ...
متن کاملSimultaneous Wire Sizing and Wire Spacing in Post-Layout Performance Optimization
In this paper, we study the wire sizing and wire spacing problem for post-layout performance optimization under Elmore delay model. Both ground capacitance and coupled capacitance in a wire are included in interconnect delay calculation. Combined with general ASIC design flow, we construct section constraint graph in each routing region and use the graph to guide segment sizing and spacing. By ...
متن کاملOn optimal ordering of signals in parallel wire bundles
Optimal ordering and sizing of wires in a constrained-width interconnect bundle are studied in this paper. It is shown that among all possible orderings of signal wires, a monotonic order of the signals according to their effective driver resistance yields the smallest weighted average delay. Minimizing weighted average delay is a good approximation for MinMax delay optimization. Three variants...
متن کاملPower Distribution Network Optimization for Timing Improvement with Statistical Noise Model and Timing Analysis
We propose an optimization method for power distribution network that explicitly deals with timing. We have found and focused on the facts that decoupling capacitance (decap) does not necessarily improve gate delay depending on the switching timing within a cycle and that power wire expansion may locally degrade the voltage. To resolve the above facts, we devised an efficient sensitivity calcul...
متن کاملWire width planning for interconnect performance optimization
In this paper, we study wire width planning for interconnect performance optimization in an interconnect-centric design flow. We first propose some simplified, yet near-optimal wire sizing schemes, using only one or two discrete wire widths. Our sensitivity study on wire sizing optimization further suggests that there exists a small set of “globally” optimal wire widths for a range of interconn...
