Abstract
An integrated circuit has a built-in self-test (BIST) arrangement (60). The built-in self-test arrangement includes a read only memory (ROM), (140) that stores test algorithm instructions. A ROM logic circuit (410) receives an instruction read from the read only memory and produces a group of output signals dependent upon the instruction. A BIST register 420 receives and stores the group of output signals from the logic circuit for controlling self-test of the integrated circuit.
