![]() The alarm will be on when clock time is equal to alarm time. The clock time can be set using timeset switch and the alarm time can be set using alarmset switch. The proposed digital clock design is enhanced using the digital operations: counting, comparing, incrementing and decrementing. The clock time and alarm time can be set using the dip switches on the board. The FPGA and on board clock will generate the timing signals. As soon as the FPGA is switched on, the clock starts. This project makes use of FPGA for the hardware implementation of digital clock. CHAPTER 2: Overview of Implementation and Prototype Verification of Digital Clock Using FPGA 2.1 Introduction Thus we can have more enhanced digital clock with alarm. We can also generate a clock with more frequency from the default frequency of the kit. From this paper we can improve some things like instead of displaying only secs and mins we can display total hrs,mins,secs. It uses the already existing blocks like counter, decoder, multipier. ![]() Out of total 4MHz,it used only 1hz frequency with 22 bit register. The digital clock displays the time only in minutes and seconds with more delay. The research paper by Parth Mehta shows the reports of designing a simple digital clock on spartan3 FPGA kit. It can used to implement different combinations of combinational and sequential logic functions. Logic block of an FPGA can be configured in such a way that it can provide functionality as simple as that of transistor or as complex as that of a microprocessor. The report made from FPGA tutorial “Over view on FPGA” states that FPGA provides its user a way to configure and these specifications offer the fuzzy logic a large amount of logic in single IC: The intersection between the logic blocks and the function of each logic block. This paper presents an Experimental implementation of digital logic designs on the Altera DE2 board which presented as an educational and development board, in order to check the flexible implementation with FPGA and to get the better and safely ways to use these specifications during any design implementations. The paper focuses that in control applications, most of the physical systems require a real-time operation to interface high speed constraints higher density programmable logic devices such as field programmable gate array (FPGA) can be used to integrate large amounts of logic in a single IC. The paper FPGA-based Implementation of Digital Logic Design using Altera DE2 Board depicts the clear picture of significance of FPGA. From this paper we can understand clearly about FPGA. ![]() The importance of timing ,area, power analysis is also explained. It gave a clear description of internal architecture of FPGA and its related hardware description language.It also explained about the design flow of like synthesis ,place, routing etc. It also stated the future scope of FPGA and its applications. The research paper “Basics of field programmable gate arrays” by Waqar Hussian stated the need of FPGA(field programmable gate array) when compared to other programmable logic devices. The development of FPGA board is a part of the research. Several authors have made different researches to minimize the power requirements in manufacturing an integrated chip and to have high flexibility and performance. The digital systems owe the versatility and superiority over analogue methods to the fact that they do not get affected by spurious fluctuations in voltage have greater precision and accuracy and can store billions of bits of information in a relatively small space. These days, numerous applications in Electronics and other technologies are using digital techniques to perform operations that were once performed by analogue methods. The advances in digital technology have been phenomenal over the years and that giving birth to digital system design which continue to serve as a great source of succour and comfort to mankind in many ways. It displays the time in format of hours:minutes: seconds. ![]() The digital clock designed is a 24-clock hour format. The feature like alarm is also set by using alarm set and alarm on switch assigned on kit. The digital clock by default displays the run time and time can be set by using time set assigned to switch on board. The main objective of the digital clock is to display the time digitally using 7-segment display on Artix-7 FPGA Board.
