i just finish read Avalon mm Interface Spec Sheet . and i tried to make it. 

 

1.  I Dened like that Nios.. 

2. Nios Connection

 when Connection Initial Nios Core Settings don't have Burst Count [32] so i tried to make it

 - nios → Caches and Memory Interfaces → Data Cache → Add Burstcount signal to data_master → Enable 

 - Avalon MM -Slave          <---->    NIOS Core Data Master 

 : Burst_Count [32]          <----->  : none

 : ReadDataValid [1]        <----->  : ReadDataValid [1]

: Addr [8]                            <---->  : Addr [14] 

: Read [1]                            <----> : Read [1]

: Read_Data[32]                <----> : Read_Data[32]

: wait_Request [1]            <----> : wait_Request [1]

: write [1]                           <----->: write [1]

: Write_Data [32]          <----->: Write_Data [32]  

:   none                               <-----> : Byte_Enable [4]

:  none                                 <----> : debug_mem_slave_debugaccess_to_roms [1]

 

 

for burst transfer is it good connection?

How about the byteenable signal (Master -> Slave)?
