The authors describe the design of an LSSD- (level-sensitive-scan-design-) based LFSR (linear feedback shift register) which is capable of changing seeds by applying a pair of clock pulses at the time of the change. This LFSR is controlled by two separate clocks, one for the normal LFSR operation and one for the change-of-seeds option. The newly generated seeds are uniformly distributed over the entire pattern space. The change of seeds is fast, since it is accomplished by a pair of clock pulses rather than by long scan operations.
