HARP: HArd-wired Routing Pattern FPGA placement and routing

Modern FPGA architectures provide ample routing resources so that designs can be routed successfully. However, providing such great flexibility comes at a high cost in terms of area, delay and power. HARP is a new routing architecture that has a mixture of hardwired and traditional flexible switches to improve the area, power and performance.

[3D-ADOpt] TPR: Three dimensional Place and Route for FPGAs

Three dimensional IC fabrication where multiple active device layers are stacked is becoming a viable process. CAD tools are needed to map circuits on such architectures. We have extended both our PPFF (partitioning-based) and the VPR  tools to perofrm placement and routing for 3D ICs.

PPFF: Partitioning-based Placement For FPGAs

PPFF is a partitioning-based placement tool for island-based FPGAs. It is built on top of the VPR code. Use of a partitioning engine results in 3-4x speedup compared to VPR (which uses Simulated Annealing), while generating placements that are as good as VPR's. The high quality of the placement is the result of an "alignment" heuristic combined with a routing resource budgeting during partitioning.
