Ilinx Vivado Usage Details (3): Using the IP CoreAuthor:zhangxianheIP Nuclear ( IP Core )There are many IP cores in Vivado that can be used directly, such as mathematical operations (multipliers, dividers, floating point arithmetic, etc.), signal processing (FFT, DFT, DDS, etc.). IP core similar programming in the function library (for example, C language in the printf () function), can be directly called, very convenient, greatly accelerated the development speed.mode one: Use

, generally small, More widely used, the rest of the simulation tools, such as Ncsim,modlesim, can be directly dump FSDB files by loading Verdi pli (typically located under the Share/pli directory in the installation directory). The Fsdb file is Verdi uses a proprietary data format, similar to a VCD, but it is only a useful information to signal the simulation process, removing the information redundancy in the VCD, like the VCD data for a Huffman encoding. Therefore, the FSDB data volume is sma

Extraction and Analysis toolThe Debussy itself does not contain an emulator (simulator) and must be called to an external emulator (such as VERILOG-XL or Modelsim) to generate a Fsdb file, and its display waveform unit "Nwave" can be displayed by reading the Fsdb file to show the change of waveform or signal valueQuick Start five-part: (Debussy v.5.2)1.

chip design is divided into front-end design and back-end design, front-end design (also known as logical design) and back-end design (also known as physical design) does not have a uniform strict boundaries, involving the process-related design is the back-end design. 1. Specification Development Chip specifications, like feature lists, are the design requirements that customers present to chip design companies (known as fabless, fabless), including the specific functional

Place the icon symbol by clicking "Places" Sheet symbol or by icon. 1Figure 1We can enter an identifier in the "Designer" area, and if the identifier contains a statement with the Repeat keyword, you can also implement multi-channel functionality (detailed below). You can implement a call to a child sheet by entering the name of the sub-sheet file (not case) you want to invoke in file name. There are other ways to generate a chart symbol, see below.When the multi-drawing project is comp

Programmable devices are the guarantee and carrier for the realization of "soft" design.Design method and design content of designing electronic design engineer is changing constantlyElectronic Design Engineer's design method and content actually also has been changing, the electron tube era, the design engineer must grasp the electron tube the performance and the design key point, the transistor age, the design engineer must be familiar with the circuit function and the establishment, the int

the settling time.7. How do you embody this relationship in Verilog?In Verilog to generate a trigger must have this sentence always @ (Posedge CLK or Negedge rst_n), there is not necessarily a trigger to produce this sentence. Take a look at the following code: always @ (posedgeornegedge rst_n) begin if(! Rst_n) 0; Else if 1 ) 1; Else 0; Endbyte_flag is also clk_200m

A: PrefaceThis blog is written by a friend of mine, who wants to learn the design of the PCIe DMA controller based on the FPGA, but there is no suitable xilinx development Board on hand, and xapp1052 does not provide the simulation code to make his learning difficult. So I think, or use EDK to build a small system, and then use Modelsim to simulate the xapp1052 DMA transceiver control, this should be the most comprehensive understanding of PCIE_DMA, I hope everyone will be helpful.Second: Pre-pr

Every time Linux is installed it is painful and joyful (including this one). The earliest contact with Linux was supposed to be 2006, when the most common Linux was Red Hat, but the first Linux I installed was a red flag. Because at that time the red flag linux6 (code should be Everest) just released, is the school propaganda, affected by this, on their own computer tried a bit (then the small broken Ben incredibly also installed). At that time, the small broken Ben in the summer, often overheat

Recently it was completely turned into code for migrant workers. See the end of C + + (C + + Training) programming and do not know when to complete the Verilog Parser. Here are some of the new realizations that have been acquired during this period, sorted by the order in which the brain is enlightened (i.e., no order):1. Bison and Flex. I knew it a few years ago, but I've never been in a quiet mind to learn. It is now hard to use on the scalp. Bison
