Design Assistant Critical Warnings

Hallo all,

I get a number of Critical Warnings with respect to lpm_ff and lpm_counter:

Below are few:


Rule A102: Register output should not drive its own control signal directly or through combinational logic - Structure 1
Application_Logic:inst1|Exp_Box:inst2|lpm_ff:ff_Last_Image|dffs
Application_Logic:inst1|Exp_Box:inst2|_~3
Application_Logic:inst1|Exp_Box:inst2|lpm_ff:ff_event_HStrig|dffs
Application_Logic:inst1|Expe_Box:inst2|lpm_counter:cnt_ext_HStrig|cntr_6ik:auto_generated|cout_actual

Can these warnings be ignored? Moreover I am using Altera Quartus 11.1 Web Edition. Could it be because of Open Core Plus?

Regards!
