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....

Hello, thanks for the reply.

The schematic and simulation waveform of JOS_counter_32 are captured and a picture is attached.

I am correcting some posts in the question; Correct t0 to t7 as normal waveforms and t8 to t31 as abnormal waveforms. It was not confirmed after t13.

Best regards,
