  • Analog and mixed signal IC layout system
    Patent number: 7739646
    Abstract: A computer-based placement and routing (P&R) tool stores a set of circuit patterns, each describing a separate device group by referencing each device of the device group and by indicating which device elements forming the referenced devices are interconnected by nets, a set of placement patterns, each providing a guide for placing IC device elements forming a device group described by a corresponding one of the circuit patterns and a set of routing styles to act as guides for routing nets between device elements placed in particular patterns. To produce a layout for an analog IC described by a netlist, the P&R tool identifies each set of devices in the IC forming a device group described by any of the circuit patterns.
