[Discuss-gnuradio] modelsim help using megacells

[George Nychis]

Hi all,

I am having trouble running a testbench in ModelSim which uses 
megacells.  I added megacells such as fifo_4kx16_dc.v and fifo_1kx16.v, 
but when trying to simulate I get errors such as:

Error: (vsim-3033) 
Z:/gnychis/fpga/usrp/fpga/megacells/fifo_4kx16_dc.v(89): Instantiation 
of 'dcfifo' failed. The design unit was not found.

I can find dcfifo in the altera_mf library, and it builds just fine. 
I'm not sure how linking goes in ModelSim?  I added altera_mf to my 
search and still get an error:

# ** Error: (vsim-3033) 
Z:/gnychis/fpga/usrp/fpga/megacells/fifo_4kx16_dc.v(89): Instantiation 
of 'dcfifo' failed. The design unit was not found.
#         Region: /tb_timestamps/rx_buffer/rx_usb_fifo
#         Searched libraries:
#             C:/altera/72sp2/quartus/eda/sim_lib/altera_mf
#             work

I'd greatly appreciate any help.

Thanks!
George
