Abstract

The present invention describes a method and apparatus for placing flops in a complex circuit design. Initially, the method calculates a physical range for every net that requires a flop, within which the flop can be placed satisfying the timing requirement. After the physical range is defined, the method groups these flops and determines a block where these grouped flops can be placed. Grouping these flops into one block (flop station) can preserve a compact layout for the design. The flops are then connected to appropriate nets.
