Optimal Design of Flexible Printed Circuit Routing Based on Heuristic A* Algorithm
The unique physical properties and routing requirements of flexible printed circuit lead to high routing complexity.Therefore,a routing optimization method of flexible printed circuit based on heuristic A* algorithm is designed.The routing design of flexible printed circuit needs to minimize the routing cost while meeting the strict constraints such as component spacing and through-hole spacing.In order to achieve this goal,the heuristic A* algorithm is introduced.With its efficient search mechanism and heuristic evaluation method,A* algorithm can guide the search process to approach the optimal solution.When constructing the routing model of FPC,the A* algorithm was combined with these constraints,and through optimizing the search strategy,the algorithm could find the optimal routing scheme under the premise of satisfying all the routing rules.The experimental results show that flexible printed circuit routing optimization method based on heuristic A* algorithm reduces the routing length from 6 200 mm to 5 678 mm and the routing complexity from 9.8 points to 9.0 points in case 5,which proves that the heuristic A* algorithm has significant advantages and potential in the field of FPC routing design.
