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.
