Abstract :
In this paper an innovative routing methodology considering wiring symmetry (WS) for multiport multiterminal (MP/MT) signal nets of analog and mixed-signal integrated circuits (ICs) is presented. In our work, first, an electromigration (EM)-aware wiring topology for each power and signal network is constructed directly from the netlist, and then, several embedded symmetry rules between wires are automatically identified and applied in the global and detailed routing phases. The use of such MP terminals strongly enhances both the ability to route the circuit and the WS. The design flow is demonstrated for the UMC 130nm design process.
