Patent ID: 7401315

Claim:
A system on chip (SOC) having pre-verified, package-level intellectual property (PLIP), the system comprising: at least one intellectual property (IP) core formed on an integrated circuit die, said at least one IP core having external connections with respect to said die; a package generic unit included within said at least one IP core, said package generic unit configured for providing external interface functions with respect to the SOC, wherein said package generic unit is pre-verified in silicon and independent of the specific packaging of the SOC, the package generic unit comprising a powering and level shifting sub-block configured to handle package independent power distribution and to convert voltages from an internal level used within said SOC to an input/output (I/O) signal level, and a custom internal interface sub-block configured to separate SOC control signals and I/O signals; and a package adaptation unit included with said at least one IP core, said package adaptation unit configured for providing external interface functions with respect to said SOC, wherein said package adaptation unit is pre-verified in silicon and dependent upon the specific packaging of said SOC.
