How do they compare their capacity? "Of course, most of the time, when I design for the customer, I will use the highest capacity products directly, because our products are not sensitive to cost. However, this is still a comparison of the two products, simply write some of

After one months of bump, the problem of the driver of the Development Board finally solved, the time of the maniac also vividly, how many times on the brink of collapse.It's funny to think, before this method is to open the Regedit registry, and then search for Altera related drivers, not specific (may not be searched), and then delete all the Altera USB related registry, it is OK.Have tried this method be

DDR2 Circuit DesignHigh-speed large-capacity cache is an essential hardware in high-speed big data applications. At present, the use of a wide range of high-speed large-capacity memory in FPGA system has a classical low-speed single data rate of SDRAM memory, and high-speed dual-rate DDR, DDR2, DDR3 type SDRAM memory, The DDR series of memory all require the FPGA chip has the corresponding hardware circuit structure support. For the Altera Cyclone IV

But remember: the human brain is the best optimizer! Introduction: OverviewFPGAs are increasingly used as Parallel Processing engines for demanding digitalSignal processing applications. benchmark results show that on

Currently, many people install Xilinx and Modelsim separately. Therefore, when using simulation libraries of chip manufacturers such as Xilinx or Altera, libraries cannot be found; because Modelsim does not own the simulation libraries of FPGA manufacturers, you must manually compile these libraries. Below I will introduce three methods to increase the library problem of Xilinx or Altera: 1. find the inst

For job requirements, the two high-level language synthesis tools were applied, and the typical algorithms were implemented and evaluated (data is temporarily kept secret).Briefly talk about the experience of using.1. Altera OpenCL SDKFirst, you need to install Quartus (more than 13.1 version) and the supporting Soc EDS, respectively, apply for two license, one for the OpenCL SDK, one for soceds, indispensable.Then need to have implementation platform

AbstractQuartus II is a large but extremely powerful component. Beginners are often lost in the us II category, altera provides technical training for beginners, focusing on "all Chinese 』!! IntroductionQuartus II functions are even greater than Visual Studio. Even after two years of research on FPGA and niosii, many functions of Quartus II and niosii have not been used, today, we found that Altera was ver

I just got the official Altera max10 evaluation board provided by Junlong! Please share it with us. The board is very simple, and I/O ports are all extended. Other functions are basically not available. FPGA model: 10m08sae144c8ges, 144-pin encapsulation, single-power supply, 12-bit AD function integrated, 8 K logic unit. You can take a look at max10 datasheet. Http://www.heijin.org/forum.php? MoD = viewthread tid = 31007 extra = Page % 3d1 Let'

A good timing constraint can be used to guide the layout and wiring tools to weigh and obtain the optimal device performance, so that the design code can reflect the designer's design intent to the greatest extent possible. 2 timequest is an ASIC-style static timing analysis (STA) tool added by Altera to the 6.0 software. The Synopsys Design constraints (SDC) file format is used as the time series constraint input. 3. timequest checks the creation tim

Two companies on the pin type of the detailed definition, although many similar, but there are a lot of different Oh!!!(3) Altera's IO feature does not have a pull-down resistor! Xilinx's IO structure also has a pull-down resistor.I developed a project encountered such a problem: the transmitter, the power is required to output low level.

In Chip Planner, when you watch your feet, you'll see the pin and pad appear at the same time,such as pin120/pad174 Bank 4So what's the difference?Pin refers to the chip is packaged in the pin, that is, the user sees the pin;Pad is the pin of the wafer, is encapsulated in the inside of the chip, the user can not see.There is also a wire connection between the pad and the pin.Pad also refers to the input and output buffer/register unit.Further in the Resource property Editor see the PAD as follow

The structure of an IO in Chip planner is shownThe left side is the output section to the right of the input section, but will notice two structure: 1, register, 2,delay moduleHere's my guess: These two structures are designed for timing optimization and are mentioned in Altera's timing optimization documentation for the fast input and output registers in the Io cell.If you have the correct timing constraints, the Quartus software can automatically determine whether the register is placed in the

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

When using the Altera device for design and Modelsim for post-simulation, you must first set the tool in Quartus, setting -- edatool -- Simulation-Tool Name --- Modelsim (OpenGL ); Then perform full compilation. The simulation folder is generated under the project directory. The internal Modelsim folder contains three files *. the VO file is the simulation model file after layout and wiring ,*. SDO files are standard delayed files. Add *. Vo and t
