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....

The reason JOS_counter_32 behaved abnormally was my mistake.

The module JOS_COUNT_4_CiRs used in JOS_counter_32 has been found to be misdesigned. I misunderstood Carry's concept and designed it.

Now it is working fine. The JOS_COUNT_4xor_CiRs module that works normally is attached.

The reason I designed the JOS_counter_32 module is because LMP-COUNTER (COUNTER_14) does not work, and it is limited to 8 bits by JOS_counter_32, but I have confirmed that the system works.

Is there a problem with my PC?

Or, is the installed Quartus Prime 19.1 installed incorrectly?

If the module is normal, is it a compiler problem?

What can I offer you for review?

Best regards,

    Hello,

    JOS_counter_32 was fixed by me, and now all bit output is normal.

    Thank you.
