Abstract
A system and method for initializing a register file during a test period for an integrated circuit, wherein the register file has one or more input ports. A counter, when enabled, is initialized and counts at each write cycle of the register file and outputs a current count value to the input ports of the register file to pre-load the register file to a known state.
