摘要： A tool that a user may employ to assemble the components of a circuit in a floor plan design. The tool provides a user interface that displays the placement of blocks in a floor plan design, and the routing of wires among the blocks. When the designer moves the placement of a target block, the user interface automatically moves any adjacent blocks that would impede the movement of the target block and any block that would impede a block moved in response to the movement of the target block. The user interface may also respond to movement of a target block by showing how various features of the circuit will change as a result of the move. Thus, the user interface may show that moving one block closer to another block will create undesired wiring congestion in the circuit. The user interface also may show when moving a block will result in wiring connections that are too long to maintain a desired voltage level. The tool may also automatically move the placement of related blocks as a group, so that various attributes, such as a minimum distance between adjacent blocks, are maintained.
