In this paper, we propose a fast placer for FPGA placement on a new commercial hierarchical FPGA device. The novelty of this research lies in the application of a multilevel V-shape optimization flow including an architecture related cluster process and a constructive placement. The new placer can handle large-scale FPGA placement problem quickly. Experimental results show that the proposed placer...
In this paper, we propose a fast routability-driven routing algorithm for hierarchical FPGAs (HFPGAs), using several strategies to steer the automated process of rip up and reroute in order to speed up the process and reach the same effectiveness of Pathfinder's negotiation mechanism. Net is expelled from congestion zone to resourceful zone. The algorithm is divided into two procedures. First, it...
Nowadays, FPGA architecture has been improved rapidly, and more and more hard structures are integrated on heterogeneous FPGA chips. RTL technology mapping is one of methods to solve the problem of making use of those hard structures efficiently. However, the traditional RTL mapping tools can not do optimization on the delay on interconnect wires which can not be ignored in the current integrated...
