US Patent 7444602 Method of generating ASIC design database

When a function design has been carried out by an RTL description using an HDL language, a CPU of an integrated circuit design support apparatus writes data such as a simulation time, a layout area, a timing and a power consumption into a header portion of the RTL description. The CPU stores, as one file, the RTL description comprising the header portion serving as a reuse design database, and an entity portion, in a hard disk drive.
