Dear everyone!  

I couldn't understand the "address Behavior" clearly, which is in page 67 of mnl_avalon_spec.pdf.  

In my nios2 system, tristate-bridge is used.  

1, for SDRAM, connect FPGA-pin-addr0 to SDRAM A0 ,tristate-bridge is used 

2, for SRAM, connect FPGA-pin-addr2 to SRAM A0 ,tristate-bridge is used 

3, for a 8bit external chip, 

connect FPGA-pin-addr0 to chip A0 ,tristate-bridge is used 

 

3, for a 16bit external chip, 

connect FPGA-pin-addr1 to chip A0 ,tristate-bridge is used 

 

Is't right? 

 

Could you please tell me what the avalon_bus_fabric do ? 

and tell me the detailed dfifference between tristate-bridge and non_tristate-bridge! 

 

Best Regards!
