fpga startup problem

--- Quote Start ---

Hello, thanks

Jtag does not start. I can not program sof

In verilog, i program the user LEDs so that they are always on. When the power is turned on, these LEDs blink 1 time and nStatus smoothly changes its value from 0.7v to 1.3v and back.

Could you tell me at which points (pins), you can check the power? I have control points 0.9, 2.5, 3, 3.3 on the board, they all show the correct values

If you say the Jtag does not start, then in your earlier message , are you referring to the compilation process?.

I also worry that when I program in quartus my epcq256 , the first 26% of the process takes a long time (about 3-4 minutes), and then the process goes to 100% very quickly (in 1 second). At the same time he writes that everything went well.

On another my chip (cyclone IV) the process is smoothly slow all 100%. Maybe this is where the problem lies.

A few things:

1. Have you assigned a valid pin to signal_1 ? (which is connected to the User LED - usually given in the user manual along with the development board. This assignment will be made in the QSF file or in a TCL file which you can source). If you do not manually assign a valid pin, it will not work.

2. Ensure the JTAG connection detects your board, and program it using the correct FPGA sof file.

If you can give us more details about the process you are following, we can help.
