In peripheral to peripheral communication, USB2.0 continues to occupy prominent position. With the emergence of USB2.0 peripherals, figuring out a standard, reliable and robust approach that can validate USB2.0 on System on Chip (SoC) is the need of an hour. The performance of USB depends fundamentally on electrical characteristics. Using this innovative(More)
USB forms the backbone of communication to external world. When a USB device is attached to a USB host, a sequence of interaction happens for establishing the communication channel, known as enumeration. This paper explains the enumeration process of USB2.0 in detail and discusses the challenges faced during post silicon debug of couple of issues related(More)
Real world communication are analog in nature whereas data processing happens in digital domain. This leads to generation of Mixed Signal design. With reference to USB, ULPI PHY serves as mixed design component that is present in most of today's gadgets. Because of its high speed and complexity, there is a need to check the individual design features of the(More)
This paper presents the design of digital combinational lock by using Finite State Machine. The digital combinational lock presented in this paper is equipped with advanced features wherein the user can set the combination of his or her choice “n” number of times. The inclusion of built in self testing (BIST) capabilities in the present system(More)
The demand of greater speed in USB communication has given birth to 4th generation standard named Super Speed USB with 10 times increase in the data rate compared to High Speed USB. Super speed USB introduces a variety of features that improve performance, reduce system power consumption and extend functionality. In order to support all these enhanced(More)
