Abstract
Disclosed is an integrated circuit () comprising a plurality of cores (), at least some of the cores being located in different power domains (VDD, VDD), each core being surrounded by a test wrapper () comprising a plurality of wrapper cells (), wherein each of said test wrappers are located in a single power domain (VDD) and each plurality of wrapper cells comprises wrapper output cells () each arranged to output a signal from its associated core, each of said wrapper output cells comprising an output level shifter () for shifting the voltage of said signal to the voltage of the single power domain (VDD). A method for testing such an IC and standard library cells for designing such an IC are also disclosed.
