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
