ABSTRACT:
A method of arranging an integrated circuit to correct for hold time errors comprises fixing the position of existing cells in a design, determining hold time errors required to be corrected and placing buffer cells in spaces in the existing design. By placing buffer cells in spaces in the existing design, rather than moving cells in the existing design, the hold time can be corrected without changing the critical path.
