Announcements. Homework 8 due today. Exam 3 on Tuesday, 11/25.. Topics for exam are up on the course webpage.. Agenda. Last time:. Master-Slave Flip-Flops (6.4). Edge-Triggered Flip-Flops (6.5). Part 1. Objectives. After completing this module, you will be able to:. Describe the control sets of the slice flip-flops . Identify the implications of the control sets on packing. Control Sets. Designing. 1. Flip-Flops. Last time, we saw how latches can be used as memory in a circuit.. Latches introduce new problems:. We need to know when to enable a latch.. We also need to quickly disable a latch.. In other words, it. By. Dr. Amin Danial Asham. References. An Introduction to Logic Circuit Testing. 3. LEVEL-SENSITIVE . SCAN . DESIGN (LSSD).

A . latch. is a temporary storage device that has two stable states (bistable). It is a basic form of memory. . The S-R (Set-Reset) latch is the most basic type. It can be constructed from NOR gates or NAND gates. With NOR gates, the latch responds to active-HIGH inputs; with NAND gates, it responds to active-LOW inputs.. Lecture 9: .

A flip-flop circuit has two outputs and the outputs of the flip-flop always complement each other, . Register is built with gates, but has memory.. The only type of flip-flop required in this class – the D flip-flop . Has at least two inputs (both 1-bit): D and . clk. Has at least one output (1-bit): Q. Drysdale. Objectives of Lecture.
