The written code works fine, but the behavior is wrong.

Hello,
This is the code for the clock that displays minutes/seconds, and attaches the project folder.

The written code works fine, but the first digit of the second position becomes '4' upon reset.
That is, 04,05,06,07,08,09 -> 10,11,12,13,14,15,16,17,18,19 -> 20,21,22,23, was expected.
The problem works as 14,15,16,17,18,19 -> 24,25,26,27,28,29 -> 34,35....

I have a question.
There is nothing wrong with the code in the Verilog HDL editor,
Is there a place where I write code that can affect the behavior in other areas that are not visible to me?
For example,
Is there a place to write scripts?
Is there a place to write the header file?
Is it possible to insert hidden characters in the editor?
I wonder if code can be injected during compilation, etc.?

If possible, what can I do to prevent this problem?

Because, I feel like someone is tampering with my PC's Quartus from a remote location.

thank you.

The designed 4-digit 7-segments were coded for 24 hours and 60 minutes.
Currently attached coding is counted up in 1 second cycle for testing.

Hi,

 

What do you mean by " first digit of the second position becomes '4' upon reset". 

 

Thanks,

Hi,
I still don't understand.
I wrote a 4-bit counter asynchronously, and it was written to reset all 4 bits at the same time, but I don't understand whether bit0, 1, 3 become "0" and bit2 becomes "1".

After I uploaded a question to https://community.intel.com/t5/Programmable-Devices and programmed with my MAX10_10M02SCU169 board, the board is not working.
The programming seems to be complete, but the board does nothing.
Can you understand why this MAX10_10M02SCU169 board is not working?

I haven't made any progress since then. ^^
Because my MAX10_10M02SCU169 board is broken.......

I'm sorry I couldn't give you good news.

Regards.

Hi,

 

You may use ModelSim to create testbench and observe the output signals. I have tried to create a testbench for it but there was no result. This is because the output was not the 7-segment display. I have tried to run another similar example from https://www.fpga4student.com/2017/09/seven-segment-led-display-controller-basys3-fpga.html , the output was the 7-segment display so I'm able to observe the output signals.

 

Thanks,

Ean
