Routability-Driven Packing: Metrics And Algorithms For Cluster-Based FPGAs
Most of an FPGA s area and delay are due to routing Considering routability at earlier steps of the CAD ow would both yield better quality and faster design process In this paper we discuss the metrics that a ect routability in packing logic into clusters We are presenting a routability driven clustering method for cluster based FPGAs Our method packs LUTs into logic clusters while incorporatin...
متن کاملRPack: Routability-driven Packing Algorithm for Cluster-based FPGAs
Routing tools consume a signiicant portion of the total design time. Considering routability at earlier steps of the CAD ow would both yield better quality and faster design process. In this paper we are presenting a routability-driven clustering method for cluster-based FPGAs. Our method packs LUTs into logic clusters while incorporating routability metrics into a cost function. The objective ...
متن کاملUsing metro-on-chip in physical design flow for congestion and routability improvement
Routability, signal integrity and manufacturability are important issues in physical design and congestion reduction is a widely used method for ameliorating these problems in current design methodologies. Besides, routing congestion may create large delays in detoured global wires that can be avoided by congestion reduction. In recent years, asynchronous serial transceivers are proposed for da...
متن کاملA Full-Capacity Local Routing Architecture for FPGAs
Reconfigurable systems employ highly-routable local routing architecture to interconnect generic fine-grain logic blocks. Commercial FPGAs employ 50% sparse crossbars rather than fully-connected crossbars in their local routing architecture to trade off between the area and routability of the Logic Blocks (LBs). While the input crossbar provides good routability and logic equivalence for the in...
متن کاملA stochastic model to predict the routability of field-programmable gate arrays
Field-Programmable Gate Arrays (FPGAs) have recently emerged as an attractive means of implementing logic circuits as a customized VLSI chip. FPGAs have gained rapid commercial acceptance because their user-programmability offers instant manufacturing turnaround and low costs. However, FPGAs are still relatively new and require architectural research before the best designs can be discovered. O...
