Abstract :
This paper presents a versatile SB model with 4 sides. It is so versatile that it can cover various kinds of 4-side SB( in the following paper, we use SB for short) architectures in a 2-D FPGA. Base on this model, a new SB structure with better routability in segmented architecture is proposed. Comparing with Subset, Wilton and Universal SBs, it improves 10.1%, 3.3% and 4.6% separately. In addition, we propose a new segment distribution method in segmented architecture, which can greatly reduce circuits delay. With the same technical parameter, 10.4% average improvement in critical path is gained in a new distribution method than in VPR´s when we use the universal SB
