UNIFIED FRAMEWORK AND METHOD FOR ACCURATE CONTEXT-AWARE TIMING MODELING

A processing device determines cell boundary conditions for each of a plurality of boundaries of a cell in an integrated circuit layout and determines a layout dependent effect (LDE) impact for the cell based on the cell boundary conditions for each of the plurality of boundaries of the cell. The pr...

More Information
Summary:A processing device determines cell boundary conditions for each of a plurality of boundaries of a cell in an integrated circuit layout and determines a layout dependent effect (LDE) impact for the cell based on the cell boundary conditions for each of the plurality of boundaries of the cell. The processing device further generates a prediction of an LDE impact on one or more contents of a library associated with the cell, and performs an LDE-aware timing analysis for the cell based on the prediction of the LDE impact on the one or more contents of the library.
