HEPAPS:A PCB Automatic Placement System

  • HEPAPS is composed of constructive placement,improving placement,equivalence pins reassignment and same function elements reassignment.Based on practical demands,this paper imple- ments the constructive procedure within a set of engineering constraints and resolves the reassignment problems of equivalence and same function elements.A new topological improving method combined min-cut algorithm with simulated annealing algorithm is presented.In addition,the two-dimensional relaxed method is introduced to solv…
