第一个Flip-Flop触发器(F1)和第二个Flip-Flop触发器(F2)之间会有一些组合逻辑电路(Combinational Logic,简称CL),CL从接收到wire Q1到产生稳定输出DATA(D2)的时间为t_{pd}(这也是一个传输时间propagation time),此时从Clk的第一个上升沿开始,已经过去了t...

Data to data check:等同于data skew check,也称为non-sequential constraints,是专指两个Data pins之间的setup/hold 检查。One pin is the constrained pin, which acts like a data pin of a flip-flop, and the second pin is the related pin, which acts like a clock pin of a flip-flop. 其与普...
A Timing Path is a point-to-point path in a design which can propagate data from one flip-flop to another ·Each path has a start point and an end point ·Start point: Input ports or Clock pins of flip-flops ·Endpoints: Output ports or Data input pins of flip-flops Timing Path Gro...
The complementary outputs of a master slave flip flop are made symmetric, with substantially zero timing skew over all process, voltage and temperature conditions. This is accomplished by utilizing a master latch and a pair of identical slave latches. Although the complementary outputs from the mast...
方法十六:split multi-bit flip-flop 因为MBFF cell内部的公共走线和公共的晶体管更多,所以其本身的load更大,那么transition time就更大,delay就更大;所以可以通过拆分MBFF cell来修setup violation。 方法十七:打拍 打拍就是在reg2reg path中间再加一个reg,一个周期搞不定的事情,分成两个周期来做。
He is an adjunct professor of computer science and computer programming.Cite this lesson In this lesson, you will learn about bus timing diagrams and how to use a bus timing diagram to describe the flow of data in a system bus. Examples of a system bus and a memory read/write operation ...
Coming to the second flip flop, here the waveform generated by flip flop 1 is given as clock pulse. So, as we can see in the timing diagram when Q0 goes transition from 1 to 0 the state of Q1 changes. Here don’t consider the above clock pulse, only follow the waveform of Q0. ...
A block diagram of the demodulator circuit according to the invention is shown in FIG. 1 wherein corresponding parts to those in FIG. 12 have the same references. In this figure, 8 is a low pass filter tuned in 0 Hz, 9 is a bandpass filter tuned to +ωk(modulation data clock frequen...
