Schematic Design, Optimization, and Pre/Post Layout Verification of 3-bit Irregular Sequence Counter
The design and implementation of a 3-bit irregular sequence counter are presented in this report. Three JK flip-flops are used to implement the counter, and their outputs are connected to one another's inputs to form a feedback loop. The flip-flops' outputs will toggle in a predetermined order thanks to the feedback loop, and this will produce the counter's output. The counter is built to produce a wide range of irregular sequences while also being as effective as possible. The counter is also made to be simple to implement in hardware, requiring the least number of parts. The counter has been implemented and tested in a Cadance simulator. The results of the simulation show that the counter can generate the desired irregular sequences correctly. The circuit-designed technology kit is gpdk045 (45nm Generic Process Design Kit).
ALU Design with Performance Analysis
This work presents a comprehensive study of the design and performance analysis of a 2-bit Arithmetic Logic Unit (ALU). The ALU can execute four arithmetic operations and three logical operations. Performance metrics, including propagation delay, power consumption, area, throughput, and accuracy, are thoroughly examined. The efficiency of CPU processing data depends on the processing of ALU. The arithmetic logic unit (ALU) is the core of a CPU in a computer. The adder cell is the elementary unit of an ALU. The results offer insights into optimizing the ALU design to enhance digital system efficiency and functionality. The students will also perform transient analysis on their circuits, analyze their responses, create the symbols of the circuits, and include the layout design of the circuits. Through continuous practice, it helps to develop the skills in using the basic features of Cadence Virtuoso, which will be useful in their future endeavors in the field of integrated circuit design.
