The present invention discloses a method, system, and design structure for making voltage environment consistent for reused sub modules in chip design, wherein each reused sub module is connected to a power grid of the chip through power connection points on a power ring of the sub module, the method including: adjusting numbers and locations of power connection points of a plurality of reused sub modules, such that the numbers of the power connection points and locations of the corresponding power connection points are identical for the plurality of reused sub modules; adjusting power wires of the plurality of reused sub modules on the power grid which are connected the power connection points, such that voltages at the corresponding power connection points are consistent for the plurality of reused sub modules. The present invention may reduce timing variation of reused sub modules in chip design and finally achieve an objective of reducing design complexity and work load and shortening the design period.
