A method for implementing package-level intellectual property (PLIP) preverification for system on chip (SOC) devices includes providing at least one externally connected intellectual property (IP) core with an SOC. A package generic unit is provided with the IP core and is 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. A package adaptation unit is provided with the IP core and is configured for providing external interface functions with respect to the SOC, wherein the package adaptation unit is pre-verified in silicon and dependent upon the specific packaging of the SOC.
