Power grid voltage integrity verification requires checking if all the voltage drops on
the grid are less than a certain threshold that guarantees proper circuit operation.
This thesis addresses the problem of correcting the grid when some voltage drops
exceed this threshold by making minor modifications to the existing design. The
method uses current constraints that capture the uncertainty about the underlying
circuit behavior to find the maximum voltage drop on the grid, and then to estimate
the voltage drop as a function of the metal widths on the grid. It formulates a nonlinear
optimization problem and finds the required change in widths that reduces the
maximum voltage drop on the grid below the threshold while keeping the total area
cost at a minimum.
