Abstract :
Logic BIST is well known as an effective method for low cost testing. However, it is difficult to realize at-speed testing, as it requires a deliberate timing design in regard to logic design and layout of the chip. This paper presents a timing design methodology for at-speed BIST, using a multiple-clock domain scheme. Some experimental test results of large industrial designs using our custom tool "Singen", are also shown.
