چکیده
This paper presents a hybrid algorithm on P/G networks of Mesh+Tree topology for ASICs. Based on existing algorithms, equivalent circuit method and TLM-ADI method, our algorithm is of linear complexity to solve P/G networks of Mesh+Tree topology. First, it uses equivalent circuit approach to compress the Mesh+Tree P/G circuit into the circuit only of Mesh topology, which is a linear complexity and error-free process. Then, it uses the TLM-ADI approach to linearly solve the reduction circuit of Mesh topology. Last, once the reduction circuit is solved, it can back-solve all leaves nodes from the base nodes of trees, which is linear complexity. Experiments show that our method is indeed linear complexity to analyze P/G networks of Mesh+Tree topology for ASICs while it speeds up two magnitudes over
