How to use <ALTERA_NOTE> section for NIOS II simulation

[Altera_Forum]

Hello, 

 Now I am trying Nios II simulation using ModelSim. ModelSim is started by Run of Eclipse.  Before adding code to <ALTERA_NOTE> section, it works well. I want to add some RTL code (including additional logic module). additional modules are stored in different directory from Simulation directory. I used menu of File > Source Directory to add location of new module .v files.  But I am facing following error.  ** Error: (vsim-3033) ../xxx.v(14053): Instantiation of 'yyy' failed. The design unit was not found.  Does somebody know how to add additional module to ModelSim.  My environments are Quartus II 11.0 Web Edition (32-Bit) Nios II 11.0 Software Build Tools for Eclipse ModelSim-Altera 6.6d (Quartus II 11.0) Starter Edition  Thank you.

Hi 

 I understood that I can resolve this problem by adding include sentence to <ALTERA_NOTE> section at the out of testbench.  Thank you.
