Metastability and Synchronizers A Tutorial

In flip-flops, metastability means indecision of whether the output should be ‗0‘ or ‗1‘. Here is a simplified circuit analysis model. The typical flip-flops in Figure 2 comprise master and slave latches and decoupling inverters. In metastability, the voltage levels of nodes A,B of the master latch are roughly mid-way between logic ‗1 ...

Modeling Latches and Flip-flops - Xilinx

www.xilinx.com

• Model various types of latches • Model flip-flops with control signals Latches Part 1 Storage elements can be classified into latches and flip-flops. A latch is a device with exactly two stable states: a high-output and a low-output. A latch has a feedback path, so information can be retained by the device.

Octal D-Type Transparent Latches And Edge-Triggered Flip ...

The eight latches of the ’LS373 and ’S373 are transparent D-type latches, meaning that while the enable (C or CLK) input is high, the Q outputs follow the data (D) inputs. When C or CLK is taken low, the output is latched at the level of the data that was set up. The eight flip-flops of the ’LS374 and ’S374 are edge-triggered D-type ...

flip-flops, except for the register file, which can be implemented either with latches or with flip-flops. See Chapter 8 for more details about the register file. The core occupies an area of about 50 kGE when the latch based register file is used. With the FPU, the core area increases to about 90 kGE (30kGE FPU, 10kGE additional register file).

Defense-Grade 7 Series FPGAs Overview (DS185)

Four of the eight flip-flops per slice (one per LUT) can optionally be configured as latches. Between 25–50% of all slices can also use their LUTs as distri buted 64-bit RAM or as 32-bit shift registers (SRL32) or as two SRL16s. Modern synthesis tools take advantage of these hi ghly efficient logic, arithmetic, and memory features.
