Individually wrap the Verilog module with a VHDL wrapper. Instantiate this VHDL wrapper in the VHDL project. Also, avoid performing this wrapping functionality in a higher level of hierarchy (for example, in the top level of the design). XST does not bind the ports correctly when this method...
The example uses the default I/O standard (LVTTL). If using other I/O standards, instantiate the appropriate IBUFG_selectIO. Solution Verilog example In this example, the ACLK's frequency is doubled and used inside and outside the chip. BCLK and OUTBCLK are connected in the board outside ...
include that in the "USE altera_mf.<component_name>.all; If this doesn't work, then what you can try is to compile the altera_mf VHDL sources/library into your work library. This will include all of the required modules and your design will compile & simulate. ...

If I get your question correctly, I hope you have many modules and you want to connect them. Then you have to instantiate (something similar to function call in C) the individual modules within a new module (module_top). For example if you want to create a 4 bit adder (module_top),...
You need at least a working knowledge of both and any complex designs are likely to use both, When it makes sense I generally just instantiate Verilog modules in my VHD code. Sometimes this doesn't work as well as it should because the Verilog module takes advantage of Verilog feature...

but cannot instantiate further objects in the module hierarchy or bind ports. On the other hand, thebefore_end_of_elaboration()callbacks are made before the end of elaboration (as you might infer from the function name), so can instantiate modules or bind ports, but cannot rely on port bind...
Assign is a continuous assignment statement which is used with wires in Verilog. assign statements don't go inside procedural blocks such as always. Registers can be given values in an always block. Modules, which are composed of digital circuits, require higher level testbench modules to drive...
Qsys has an option to set the simulation language to VHDL. Did you try it? --- Quote End --- Yes, it only generates the top level in VHDL. The lower level components have always been in verilog in my experience. --- Quote Start --- ...
