Method and apparatus for enhanced static ir drop analysis

An apparatus configured to perform enhanced static IR analysis on a device, comprising:

• means for selecting a block of the device;
• means for partitioning the block into a plurality of tiles;
• means for determining an individual current demand profile for each tile in the plurality of tiles;
• means for adding the individual current demand profiles to determine a global current demand profile for the block;
• means for determining peak time points at which the global current demand profile peaks;
• means for determining, from the individual current demand profiles, instantaneous current values for each tile at the peak time points;
• and
• means for performing a static IR analysis on the instantaneous current values for each tile to identify a power grid connectivity deficiency.

An apparatus configured to perform enhanced static IR analysis on a device, comprising:
