Is there any reason why the actual behavior in this symbol is different from the schematic?

I use Quartus (Quartus Prime 19.1) Lite Edition. The attached 32-bit counter symbol outputs a duty 50 waveform from t1 to t8, but a narrow waveform from t9 to t31. JOS_COUNT_4_CiRs are all the same....

Hi,

I understand that the waveform issue has been resolved.

I tried to create a LPM_COUNTER, the maximum width supported is 256. You mentioned that the LPM-COUNTER IP does not work and it is limited to 8 bits. May I know what error you see? Is it a compilation error? Could you share the error message and steps to reproduce the error?

Thanks.

Best regards,

KhaiY

Hello,

The error message could not be saved at the time the error occurred.

Reproducing it today, it is working fine.

At that time, there was no waveform of all output bits.

In the current project, everything is operating normally, so it seems that the past state cannot be reproduced.

So, I am checking with the new project "ElectricPiano_00_00", but the problem is also confirmed in this project.

Thank you.
