摘要： A placement tool generates an optimal placement for a plurality of device modules within an analog integrated circuit (IC) subject to device matching, symmetry, and proximity constraints by first defining a multiple-level hierarchy of constraint groups, wherein each constraint group consists of elements that are subject to one of the placement constraints. Each element of each constraint group consists of either of one of the device modules or another one of the constraint groups residing at a lower level of the hierarchy. The tool then generates a hierarchical B*-tree representation of a trial placement for the IC including a separate node representing each constraint group of the hierarchy and a separate node for each of device module not included in any of the constraint groups. Each node representing a constraint group defines relative positions within the IC of each the device modules or lower level constraint groups forming the constraint group that are consistent with the placement constraint on the constraint group. The placement tool iteratively perturbs the hierarchical B*-tree to generate a sequence of trial placements for the IC design and then evaluates a cost function for each trial placement to select a best one of the trial placements as the optimal trial placement.

摘要： 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. The P&R tool then generates a separate device group layout for each identified device group using the placement patterns as guides for placing device elements within the device group layout and using the routing styles as guides for routing nets interconnecting device elements within the device group layout. The P&R tool also generates a layout for each device not included in any identified device group. The tool then generates a layout for the IC incorporating each generated device and device group layout.

摘要： A schematic diagram generator processes a netlist to generate a schematic diagram based on a set of placement rules, corresponding to a separate characteristic pattern of interconnected devices and specifying a constraint on relative placement within the schematic diagram of symbols representing devices forming the pattern. The generator identifies each set of devices in the netlist that exhibits any rule's interconnection pattern as a separate “soft group”, places a constraint consistent with the rule on relative positioning within the schematic diagram of symbols representing the soft group, resolves any constraint conflicts in accordance with a constraint resolution scheme, and then places all device symbols in the schematic diagram in a manner consistent accordance with the constraints.

摘要： A system for processing a netlist description of a circuit to generate a display of a schematic diagram including representations of cells and nets first determines positions of the cell instance representations within the schematic diagram and then displays the schematic diagram, including the cell instance representations but no representations of the nets. When a user requests a zoom in operation to display a smaller portion of the schematic diagram at a scale at which net representations can be viewed, the system determines routes for representations of nets that are to reside in that portion of the schematic diagram and then displays those net representations upon zooming in to that portion of the schematic diagram. When the user requests a pan operation to shift the display to another portion of the schematic diagram, the system determines routes for representations of nets that are to reside in that other portion of the schematic diagram and then displays those net representations upon panning to that other portion of the schematic diagram

摘要： A schematic diagram generator processes a netlist or similar circuit description to determine how to place and orient symbols representing devices forming the circuit based on a set of placement rules. Each rule corresponds to a separate characteristic pattern of interconnected devices, and specifies a constraint on relative positioning and/or orientation within the schematic diagram of a set of symbols representing any set of devices forming the corresponding pattern. For each rule, the schematic diagram generator processes the circuit description to identify each set of devices of the electronic circuit exhibiting the rule's corresponding characteristic pattern as a separate “soft group” and establishes a constraint consistent with that rule on relative positioning within the schematic diagram of a set of symbols representing the identified soft group. The schematic diagram generator then resolves any conflicts among the constraints by eliminating some of the constraints and retaining others in accordance with a constraint resolution scheme. The schematic diagram generator thereafter selects positions and orientations within the schematic diagram for all device symbols in a manner consistent with the retained constraints.
