IC design flow includes RTL design, synthesis, APR, and layout. An IC designer can choose a suitable standard cell for an integrated circuit according to the timing, area, and BCI (best cell index) of each standard cell. Further, the BCI of a standard cell can be generated by generating critical dimensions of a standard cell in a plurality of surroundings, generating a plurality of circuit parameters corresponding to the plurality of surroundings, calculating the differences of the plurality of circuit parameters and the ideal circuit parameter of the standard cell, and analyzing the distribution of the differences.

Method for determining a standard cell for IC design

A method of generating a standard cell layout includes analyzing a circuit of a standard cell layout and obtaining an analysis result, selecting a plurality of leaf cell layout according to the analysis result, and piecing together the leaf cell layouts to generate the standard cell layout.
