N2 - This paper presents a new method to automatically generate hierarchical placement rules, which are crucial for a successful analog placement. The netlist, a library of building blocks and a symmetry analysis are the basis to determine a constraint requirement graph, which comprises five types of proximity, matching and symmetry constraints. According to the priority of the constraint types, a hierarchical partitioning of the circuit into matching, proximity and symmetry groups is then automatically computed and forwarded to a state-of-the-art placement tool. Based on experimental results, we show that the new approach generates more placement rules and leads to better circuit performances according to post-layout simulation compared to a commercial approach.
