DS-LFSR: a BIST TPG for low switching activity
A test pattern generator (TPG) for built-in self-test (BIST), which can reduce switching activity during test application, is proposed. The proposed TPG, called dual-speed LFSR (DS...

A highly regular multi-phase reseeding technique for scan-based BIST
In this paper a novel reseeding architecture for scan-based BIST, which uses an LFSR as TPG, is proposed. Multiple cells of the LFSR are utilized as sources for feeding the scan c...

Vulnerability of Nonlinear Filter Generators Based on Linear Finite State Machines
We present a realization of an LFSM that utilizes an LFSR. This is based on a well-known fact from linear algebra. This structure is used to show that a previous attempt at using a...
