Hi all,

I need to simulate an SPI Interface built with EFB.

I'm not able to find the EFB model.

I mapped the library models to

not sure if that's what you're looking for:


Here you should find the encrypted EFB stuff. But whether you can 
actually use it, depends on your simulator..

thanks for your reply.

Actually I used Modelsim Altera SE (free edition inside Quartus 
environment), when I tried to map 
$DIAMOND_DIR/cae_library/simulation/blackbox/ the tool said

"Bad library format, library not compiled with ALTERA compiler"

So, I think I can't use that Modelsim version for EFB simulation

Now, I switched to Active HDL (free edition inside Diamond environment).

Then, they say to use the Lattice-provided pre-compiled libraries for 
Aldec Active-HDL simulator
but in this directory there is not the EFB model for simulation.
I have no so  much experience with this simulator, so I'm trying to 
figure out this problem

What simulator do you use?

AFAIK the EFB model is only included as encrypted Verilog model. 
ActiveHDL Lattice Edition supports mixed language, so this is not a 
problem. But you need to reference the Verilog MachXO2 library, 
ovi_machxo2  i.e. with -L option from the vsim command, in the startup 

Create a simulation project with the Diamond simulation wizard, and take 
a look at the generated startup script (<yourname>.ado) in the 
simualation directory <yourname> to see how.
