How to simulate Nios 2 processor based system correctly

Hello everyone,

I am working on Network on Chip. I made one system including Nios II Processor, uart, on-chip memory, and my vhdl file in which nios 2 sends and receive the data. For this system i have to check whether my system works correct or not...

Now i want some help regarding simulation that I invoke Modelsim Altera from Nios 2 software and compiles the file .tcl file then i want only these signals in wave window (write, write data, read, read data and so on). For this i need wave.do file but i don't know how to make it....

Please help me because i have already work on it from one month ago...

Thanks
