A method for analog circuit placement is proposed. The method comprises inputting a plurality of modules, a netlist and a constraint file. Next, it is performing a step of establishing a QB-tree construction. Then, a node perturbation of QB-tree is performed after establishing the QB-tree construction. Subsequently, it is performing a step of a look-ahead constraint checking to check whether meet constraints of the constraint file or not, followed by performing a QB-tree packing when meet constraints of the constraint file. Next, it is performing a process of performing a cost evaluation.
