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

Design Concept of FPGA Asynchronous FIFO (2) First, we will discuss the Gray code encoding method: Let's first look at the 4-bit gray code. When MSB is 0, the positive count is displayed. When MSB is 1, that is, the pointer has already passed through, and the highest digit is flipped. At this time, the gray code is counted in reverse order, the entire set of data is symmetric centered on the maximum value (depth), and each number meets the Gray code

Let's talk about it first. Use FPGA to allow buttons to control the display of digital tubes. If you use Quartus II, you just need to find a book. There are image examples on the Internet. A typical example of FPGA application development. Let the digital display, I still 51 Single-Chip Microcomputer idea, come to an input, then output control. Start with a simple Copy a program from the Internet:/*The deco

The zero crossing detection method is the function of the comparator. It can convert a sine wave of a certain frequency into a square wave or a pulse wave. This is necessary in the test frequency and other places, because FPGA only recognizes the edge, but does not recognize the sine wave. The algorithm is divided into two parts: the determination of the zero point and the generation of the pulse wave. Why do we need to determine the zero point. We
