Design and analysis of gray code generator as test pattern generator

Gray code is a process of encoding integers as a sequence of binary bits. These binary bits are arranged in such a way that two adjacent integers differ by a single binary digit. There are different types of grey code such as reflected binary, uniform balanced, antipodal, and so on. This paper mainly focuses on the reflected binary grey code. The reflected binary code is light weighted. The primary function of counters is to produce a specified output sequence and they are also called pattern generators. This paper contains the comparison of different bits of grey counters. The parameters of comparison are static power, dynamic power, utilization, and on-chip temperature.
