A circuit and methods for placing a circuit block on an integrated circuit (IC) are disclosed. An embodiment of the disclosed method includes dividing the IC into multiple regions based on pre-determined value. This pre-determined value may be a voltage drop value measured on specific regions on the IC. The performance requirement for the circuit block is determined and placed in one of the regions on the IC. In one embodiment, the placement of the circuit block is based on the performance requirement and the measured value at specific regions on the IC. The measured value may be a voltage drop value and a circuit block with a higher performance may be placed in a region with a lower voltage drop value.
