Abstract:
IEEE1687 (iJTAG) module layout was drawn manually to study and analyze inner Reconfigurable Scan Network (RSN) in the past. To address the problem of low efficiency and low error tolerance of manual layout, a method of iJTAG module layout is proposed in this paper. Based on the traditional Simulated Annealing Algorithm (SA), this method adaptively improves the cooling strategy and constructs a constraint function considering the interconnection between SIB and TDR units to achieve the optimal layout finally. The experimental results show that the proposed algorithm increases the convergence rate.
