Abstract：
This talk introduces an approach for merging multiple FPGA designs into a single hardware design, so that multiple place and-route tasks can be replaced by a single task to speed up functional evaluation of designs, especially during the development process. The proposed approach has three key elements. First, a novel approximate maximum common subgraph detection algorithm with linear time complexity to maximize sharing of resources in the merged design. Second, a prototype tool implementing this common subgraph detection algorithm for dataflow graphs derived from Verilog designs; this tool would also generate the appropriate control circuits to enable selection of the original designs at runtime. Third, a comprehensive analysis of compilation time versus degree of similarity to identify the optimized user parameters for the proposed approach. Experimental results show that this approach can reduce compilation time by around 5 times when each design is 95% similar to the others, and the compilation time is reduced from 1 hour to 10 minutes in the case of binomial filters.
