A crosstalk-aware timing-driven router for FPGAs
As integrated circuits are migrated to more advanced technologies, it has become clear that crosstalk is an important physical phenomenon that must be taken into account. Crosstalk has primarily been a concern for ASICs, multi-chip modules, and custom chips, however, it will soon become a concern in FPGAs. In this paper, we describe the first published crosstalk-aware router that targets FPGAs. We show that, in a representative FPGA architecture implemented in a 0.18µm technology, the average routing delay in the presence of crosstalk can be reduced by 7.1% compared to a router with no knowledge of crosstalk. About half of this improvement is due to a tighter delay estimator, and half is due to an improved routing algorithm.
