Abstract

The Timing Drive Placement (TDP) system balances wirability and timing constraints so that the final released design meets timing criteria. This is achieved by dynamically evaluating the timing of critical paths during placement. TDP is significant because convergence to a timed wirable solution early in the physical design cycle is achieved, or else it becomes apparent that logic changes are required.
