Hi Richard,
Thank you for the reply.
I did not find any other problem for now.

I already revise 220model.v file and compile it with other RTL files in my project.
My design is the backend part of Arria 10 PCI Express avalon ST IP.
I can't send whole my project but instead I will send one module that instantiate lpm_counter.
You can simulete this module but you may not need to do.
Please read lpm_counter module definition in 220model.v, you can see eq output never get all zeros.

Regards,
