Abstract
A computer converts a description of an analog circuit to a physical representation in terms of devices on a personalizable chip. The devices are placed and wired automatically for fabrication of the chip. Descriptions of resistors in the circuit are expanded by wiring multiple contacts of one or more actual resistor devices on the chip. The chip uses multiple rows of devices arranged in columns; each row contains multiple transistor and resistor devices.
