Abstract
A computer-implemented method identifies at least one proprietary geometric figure from a plurality of geometric figures within a design data layout format file. The proprietary geometric figure in the design data layout format file may be replaced with a placeholder geometric figure. Cell names and connection names associated with the proprietary geometric figure are renamed from a netlist file that defines electrical connections between the geometric figures with obfuscating names. A modified design data layout format file may be generated that includes the placeholder geometric figure and a modified netlist file including the obfuscating names. The modified file enables IC designers to complete their design and checking activities, but inhibits reverse-engineering of the proprietary geometric & netlist data.
