General principles of PCB design Xilinx Learning Experience 1-pin constraints ads7830 FPGA Implementation 11:18:12 | category: Work notes | tags: | large font size, small/medium subscription The ads7830 is an 8-bit, 8-channel AD conversion chip of Ti, Which is configured and read through the I2C interface. The following is a program I have compiled using the OpenGL, which has been verified and is completely OK, the input clock is 125 MHz. After dividi

Preface: Why is it three? I and II are too lazy to move over. For details, see lazy rabbit. The image is scaled. If you cannot see it clearly, click the image to see the big image. As a simulation tool, Modelsim is an indispensable software for CPLD and FPGA. Before performing the simulation, let's talk about the harmonious installation problem. You can download the installation software from www.modelsim.com. The official website provides the latest

Example; This is a question given by the teacher. The goal is to familiarize us with the C language operation of FPGA, so as to prevent low-handed eyes. To be honest, testapp_memory is a test provided by XPS.ProgramThe principle is well understood. It is the process of writing data into and then reading data. However, when talking about our own operations, we also need to use the underlying "address Pointer". It sounds a bit messy, and there is

The first step must be the pin planner, which is the view of the four generations of black gold ep4ce15f17c8. The first is to find that their pin has different color areas, which correspond to different banks respectively. Some designs require that the pin be in the same bank (first, this conjecture is followed by verification ), what does different circles and triangles mean? View --> pin legend In the figure, the pin of several brown backgrounds is used. If you place the cursor on the pin, t

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

Here do not repeat UVM for what, do more than half a year FPGA design verification work, according to demand has been written with VHDL test procedures, recently watched a few days UVM verification methodology book, feel this is a good verification tool, now began UVM learning, So ready to use Modelsim to do a Hello world, so go to the Internet casually search the code, test, see below:[Plain]View Plaincopyprint?

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
