PPT-Analysis of Clocked Sequential Circuits

COE 202 Digital Logic Design Dr Muhamed Mudawar King Fahd University of Petroleum and Minerals Presentation Outline Analysis of Clocked Sequential circuits State and Output Equations State Table. 1 Motivation We know that digital circuits are formed by two type of components 1 Combinational circuit and 2 Sequential Circuits Combinational circuit component s are used only for logic implementation and cant store the bits ie work as memory But Both the outputs and the next state are a f unction of the inputs and the present state Recall f om previous les on that s entia l ci rcuit design involves the flow as shown brPage 2br Analysis consists of obtaining a statetable or a statediagram fr Lecture 27. Announcements. Exams returned at end of lecture. Homework 9 is up, due Thursday, 12/11. Recitation quiz on Monday, 12/8. Will cover material from Lectures 26, 27. Agenda. Last time:. Structure and Operation of Clocked Synchronous Sequential Networks (7.1). Example of a Sequential Circuit. D flip-flops. Example: . Start with A=0, B=0, x=0.. A(next)=0. B(next)=0. Y(next)=0. What . are. . A(next), . B(next) and y(next) . given that A=1, B=1 and X=1?. D flip-flops. CPU’s . program counter (PC) . register has address . i . of the . first . instruction. Control circuits “fetch” the contents of the location at that address. The instruction is then “decoded” and executed. Sequential Circuits. COE . 202. Digital Logic Design. Dr. . Muhamed. . Mudawar.

Spring term, 2012. March 26, 2012. Today’s Class. Sequential Pattern Mining. Related to. Association Rule Mining. MOTIF Extraction. Similarities. MOTIF Extraction can be seen as a type of sequential pattern mining. Chapter 5. Sequential Circuits. Combinational circuits storage (store binary information). Binary information stored defines the state of the sequential circuit. External input present state determine the binary value of outputs and change state in storage elements. COE . 202. Digital Logic Design. Dr. . Muhamed. . Mudawar. King Fahd University of Petroleum and Minerals. Presentation Outline. Introduction to Sequential Circuits. Synchronous versus Asynchronous. VLSI. Analog Circuits Design Automation. 1. Mathematical equations of a circuit. Use KCL (or KVL) to establish the currents relationship among the branches associated to each node. Use device (circuit element) I-V relationship to obtain a set of equations in which node voltages are the variables.
