Context aware processing to resolve strong spacing effects due to strain relaxation in standard cell library
Methods and systems assign an alignment context to each of the cells within an integrated circuit layout, from previously established alignment contexts, based on how the different cell widths cause each of the cells to align with adjoining cells. Also, such methods and systems retrieve standard signal delay times for each of the cells from a standard cell library. This allows these methods and systems to adjust the signal delay times for each of the cells based on which alignment context has been assigned to each of the cells, to produce adjusted delay times for each of the cells. Following this, the methods and systems perform a timing analysis of the layout using the adjusted delay times for each of the cells, and output the results of the timing analysis.
