Two-way foot, when it is output foot, is open drain. When the pin is output as a status, it is set to low level before and during the configuration. Once the configuration data is received and there are no errors, the initialization cycle starts and the Conf_done is released. When entering a pin as a state, when all da

AbstractThe speed of Altera's EDA tools is very slow. This article proposes some suggestions to accelerate Altera tools.
IntroductionThe whole product of Altera is slow in several places:
1. interval of us II.2. the timeout time of the niosii.3. the upload time of the image builder.

Here is an example of how to solve this problem with Xilinx Platform Cable USB.After plugging in the USB, view the deviceLsusb001 006View permissions for this devicels -l/dev/bus/usb/001/006CRW11895 24 :/dev/bus/usb/ 001/006You can see that the current user does not have executable permissions, and other

Recently, the great god of end China, a faint bean, published the blog fpga r D path (25)-pin, I just got a new book titled deep understanding of Altera FPGA application design. Here we will organize the knowledge of the two. I/O feature notes for the cyclone IV device will be added later.
In the previous article, the pin introduction in Altera FPGA has provided a brief and comprehensive description of the
Tribute to the originalHttp://blog.sina.com.cn/s/blog_6276db0e0101ary8.htmlTo compare Xilinx and Altera FPGAs, it is necessary to understand the structure of two giant FPGA, because of their respective interests, the two FPGA structure is different, the parameters are different, but can be unified to the LUT (look-up-table) lookup table.Take the example of Altera's Cyclone II series Ep2c35, as well as the xc3s500e of the Xilinx spartan-3e series.

Many of the friends who have done microcontroller know that after the MCU is burned to write the program firmware, then the program firmware is stored inside the MCU. The program can continue to operate even if the MCU is powered off and then re-energized. This is because the firmware of the MCU is written to write the program firmware to the MCU on-chip program memory ROM, and most modern MCU this ROM is flash memory. Flash memory can be power-down to keep data, so can realize the power-down pr

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

Solution:First, you need to convert the. BDF schematic file to a standard description file supported by third-party EDA tools such as OpenGL. In Quartus, keep *. BDF is in the active window status. Run the [file]/[Create/update]/[Create HDL design file for current file] command. In the pop-up window, select the file type as "maid, output *. V top-level file.

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.
