有人用过quartus中的simple dual port ram 的吗

--------------------------------------------------------------------------------
If you used only altera_mf.vhd from quartus\eda\sim_lib with an instantiated altsyncram (or another instantiated megafunction that itself uses altsyncram), then you must be doing RTL simulation.
As vernmid said, ModelSim will use the .vho only if you tell it to, and in that case you would have to use <device_family>_atoms.vhd and <device_family>_components.vhd in quartus\eda\sim_lib to give ModelSim the models for the ATOMs (WYSIWYG primitives) in the .vho. If you didn't use the ATOM library, then I don't see how you could successfully use the .vho.
As I recall, the .vho includes the initialization data right in the .vho file, so the .mif/.hex issue FvM mentioned would not apply if you really are using the .vho.
If you are using the NativeLink interface between Quartus and ModelSim to run ModelSim from within Quartus, then Quartus might be telling ModelSim to compile the appropriate library for you. 什么问题
