welding, this time with a cable download program. Only after the debugging is completed, the program is burned in the configuration chip, and then the chip welding, or configuration chip is easy to remove the kind of welding, This makes it easy to debug with a problem. Recommendations in the AS mode: use a board with the as download, the configuration chip has been welded on the board, the original as mode in the configuration chip with the cable to download, will automatically prohibit the con

will enter the wrong state. This foot cannot be used as a normal I/O pin. The nstatus foot must pull up a 10K ohm resistor.Conf_done.This is a dedicated configuration state foot. 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

I have summarized the programming of the Altera device as follows. I hope to comment on it more .......... Configuration file: After the logic code of the Altera us compilation is completed, the system generates the POF (Program object file) programming object file and the sof (SRAM object file) SRAM object file. POF is used to load EPC, and SOF is used to directly configure the SRAM structure of FPGA.

Under non-root permissions to run the IDE, such as VIVADO/QUARTUS/CCS, need to use JTAG when the issue of permissions, almost all USB debugging devices under Linux will encounter this problem. 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

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. Below is a specific solution from: http://www.wlu.ca/science/physcomp/nznotinas/altera_reference/Quartus_ModelSim_schematic.shtml query:Qua

You use Altera's megafunction to generate the "divider" Wizard, now you will see like that follows: // Megafunction Wizard: % lpm_divide %// Generation: Standard// Version: wm1.0// Module: lpm_divide // ================================================ ======================================// File name: div31.v// Megafunction name (s ):// Lpm_divide//// Simulation library files (s ):// LPM// ================================================ ======================================//*************

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
