logical replication, we haven't met it yet. Copy the concept first: Logical replication is an optimization method to improve timing conditions by adding area. Its most important application is to adjust the fan-out of signals. In other words, that is, the fan output is very large, so in order to increase the drive capability of this signal, many levels of buffer must be inserted, which increases the path Delay of this signal to a certain extent. In this case, you can assign values to generate t

0 is lit and the value of low three bits [3:0] in Num is separated (6 in this case) to display. When Dig_num is 1 o'clock, light the digital tube 1, separate num[7:4] to display (this separates 5). When dig_num = 2 ~ 5 o'clock, the situation is similar. Any time the value in display is converted to the De Shun signal required by the digital tube. Syntax used in this example: Decimal ' d, Hex ' H, octal ' O, binary ' B must be careful, very easy to mistake Fina

Notepad++ is a very special editor, open source software, free to use. Open fast, support up to 27 kinds of syntax (support Verilog and VHDL) high brightness display, auto complement function, and support column operation. After installing the software, the font style is set to Consolas, size 14, and the color style theme is obsidian. The following effects are set:Quartus II software can call the Notepad+ editor, and can be in error, notepad++ can directly highlight the error line. The Setup met

IMAX (full negative load) required in the entire system should be calculated first, and after determination, the rated current of the fuse is selected for imax/75% use.2) DC resistance P = I2 R, if the power dissipation is too large, consider the thermal problem.3) The rated voltage refers to the maximum voltage that can be sustained when the fuse is blown, and should generally be larger than the entire system input voltage. According to the UL standard, when choosing the rated voltage of the f

---restore content starts---This paper is a reading note on the research of linear array CCD image measurement system based on FPGA.Reading the previous summary still does not understand what the author is going to do. Then read down ....Finally saw a word "image measurement technology based on machine vision", it seems I can find literature in this aspect.Unlike most optoelectronic devices that use current or voltage as a sensing signal, the CCD is a charge signal that transforms a free distrib

I used to be stupid beforeAlways @ (Posedge signal)Such code to detect the rising edge of signal, a lot of problems.After being instructed by a classmate in the lab, he will never do so foolishly. Of course, you won't do that after reading it.The principle of detecting the rising edge: The signal is sampled using a high-frequency clock, so to realize the rising edge detection, the clock frequency must be at least twice times the highest frequency of the signal, or leak detection may occur. See t

. The specific capacitance is best for the same noise compensation as the self-resonant frequency, and we measure this phase relationship with this frequency. When the disturbance zone to the distance of the capacitance, the phase of the compensation current and the noise source phase is exactly the same as 180°, that is, the full reverse phase, when the compensation current is no longer in effect, the decoupling effect is invalid, the compensated energy can not be delivered in time, in order to

Differential Impedance correlation parametersThe spacing is 6mil, the thickness of the line width is 15mil,core layer is 12.6mil, the calculated result is 89.72ω, satisfies within the 90ω±10% range.Once the above parameters have been calculated, the wiring must be started, then the differential pair should be set in the schematic diagram. As shown in 25.13. It is defined by choosing place---directives---differential pair in the menu bar, and also note that the names need to be defined as *_n an

order to make the decimal point of the result not move.The multiplication of a fixed-point decimal with the C language is:Short q1,q2,q3;....Q3= ((Long Q1) * (Long Q2)) >> N;Because/2^n and * 2^n can be easily computed with a shift, a fixed-point decimal operation is much faster than a floating-point decimal. Let's use an example to verify the above formula:Use Q12 to calculate 2.1 * 2.2, first convert 2.1 2.2 to Q12 fixed-point decimal:2.1 * 2^12 = 8601.6 = 86022.2 * 2^12 = 9011.2 = 9011(8602

[Serialization] FPGA OpenGL series instances Sequence Pulse Generator Based on OpenGL I. Principles In a digital circuit, a circuit that can output pulse waveforms in turn in a certain order of time is called a sequential pulse generator. In digital systems, it is often used to control certain devices to perform operations or operations in the order specified in advance.A sequence pulse generator is also called a pulse distributor or a beat puls

to allow the software to change the baud rate. If we select it, we will allow it, in this way, we can use the software to change the baud rate at any time. If the software is not set, the default value is 115200 set above. In the red box 3, we set some parameters related to the serial port and check the method, data bit, stop bit, which is basically not used later. You can modify it based on your actual situation. After setting, click Next and finish to complete the build. After the build,
