Problem in creating a qsys custom component

Hello good evening,

I have written a verilog code and i have tried to create a qsys custom component using avalon mm interface i got some problems:

1. in Technology map viewer i couldn't find one of the instance of a module that included in the custom component.

2. I have written a test bench in verilog which act as control signal generated by nios and i verified my verilog code with that test bench in signal tap. but when i interfaced with nios its not working, its not writing the data into the register that is pointed by the address.

so i need some assitance from your side

Thanks and regards,
