force quartus to instantiate LPM_COUNTER from HDL

Dear All, is there any way how to force quartus to instantiate LPM_COUNTER when I describe counter in VHDL?? I have following structure: process (CLK, RESETNA) is begin -- process...

That handbook chapter says, "Implementing counters in HDL code is easy; they are implemented with an adder followed by registers."

I suspect that Quartus integrated synthesis intentionally does not infer lpm_counter. It might be that the counters created by synthesis are just as good. If you specifically want lpm_counter, you will probably have to instantiate it yourself.
