Modelsim-altera starter - Instantiation of 'dcfifo' failed. The design unit was not f

[Altera_Forum]

I am compiling the existence codes and found dcfifo, pll component are instantiated there. 

here is the dcfifo codes in side module.   dcfifo dcfifo_component (  .rdclk (rdclk),  .wrclk (wrclk),  .wrreq (wrreq),  .aclr (aclr),  .data (data),  .rdreq (rdreq),  .wrfull (sub_wire0),  .q (sub_wire1),  .rdempty (sub_wire2),  .wrusedw (sub_wire3),  .rdusedw (sub_wire4),  .rdfull (),  .wrempty ());  defparam  dcfifo_component.intended_device_family = "Cyclone V",  dcfifo_component.lpm_hint = "RAM_BLOCK_TYPE=M10K",  dcfifo_component.lpm_numwords = 512,  dcfifo_component.lpm_showahead = "OFF",  dcfifo_component.lpm_type = "dcfifo",  dcfifo_component.lpm_width = 16,  dcfifo_component.lpm_widthu = 9,  dcfifo_component.overflow_checking = "ON",  dcfifo_component.rdsync_delaypipe = 4,  dcfifo_component.read_aclr_synch = "OFF",  dcfifo_component.underflow_checking = "ON",  dcfifo_component.use_eab = "ON",  dcfifo_component.write_aclr_synch = "OFF",  dcfifo_component.wrsync_delaypipe = 4; endmodule   Should I generate them(dcfifo and pll)? any procedure to compile them after generation ?  Instantiation of 'altera_pll' failed. The design unit was not found. Instantiation of 'dcfifo' failed. The design unit was not found.  Regards Vraifluss

You might end up here if you're trying to figure how to simply use Altera libraries in your simulation.

Add the -L <library> name like below.

vsim -t 100ps -L altera_mf_ver -L altera_mf work.Example_Fifo_tb
