FFT modelsim stand alone simulation

[Altera_Forum]

I new to Quartus II and ModelSim. I am trying to simulate the FFT MegaCore and I am getting a VHDL compile error. I have reviewed the documentation but I don't see what I am doing wrong. The documentation I am looking at is "Ch 6: Simulating Altera IP in Third-Party Simulation Tools page 6-11" The Q2 generated VHDL uses the lib/package "fft_lib.fft_pack_fft_90" I don't see how the package "fft_pack_fft_90" gets included into the vcom command. I do see a binary file called "fft_pack_fft_90.vhd" which Q2 generated. 

 vcom -work work -93 -explicit fft.vhd# Model Technology ModelSim SE-64 vcom 6.1a Compiler 2005.07 Jul 19 2005# -- Loading package standard# -- Loading package std_logic_1164# ** Error: (vcom-19) Failed to access library 'fft_lib' at "fft_lib".

Hi 

 You have to compile that generated .vhd into your library and set pathes that the library is known by modelsim.   I'm more used to the GUI way, so I describe this one (command line version should be similar, but you have to add pathes yourself...)   Start Modelsim   Library -> New library [x] a new library and a logical mapping to it Library name [fft_lib] Library Physical name [fft_lib] > OK   Compile > Compile... Library [fft_lib] Filename [./fft_pack_fft_90.vhd] > Compile   Now you should see the fft_lib beside the other libraries and see the building blocks compiled into it. Open and build your simulation now.   Hope this helps, Peter
