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

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

, its configuration data is stored in SRAM and must be re-downloaded when power is added. In an experimental system, a computer or a controller is usually used for debugging, so PS can be used. In the practical system, in most cases the FPGA must be actively guided to configure the operation process, when the FPGA will actively from the peripheral dedicated storage chip to obtain configuration data, and this chip in the FPGA configuration information is designed by the ordinary programmer to the

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

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.
