A Multiple LFSR Inhibiting Structure for Low Power BIST
Feng Liu, Asic System · Journal of Electron Devices · 2002
In this paper, a multiple LFSR inhibiting structure is proposed to reduce the power consumption during BIST. The structure inhibits the non detecting sub sequences not by the vectors but by the distance numbers between the vectors. The average reduction of the internal WSA, which is used to estimate the power consumption, reaches 80.3%. Furthermore, with the increasing of inhibition times, that the area overhead increases more slowly than other filtering or inhibiting techniques is also an advantage of the proposed structure.
