Abstract :
A routing method for analog full-custom ICs which is applicable to a wide variety of circuits, including mixed analog/digital designs, is described. The router is gridless and performs electrical optimization at a symbolic level, before design rules handling. Electrical optimization includes crosstalk, resistivity, ground capacitance, and electrical symmetry. An expert system can be used as an option for handling specific constraints and to control the final results. Practical results are presented and discussed on the basis of several examples
