Honored Contributoryou have to use the "create new component" tool in sopc builder: insert your hdl file in the "hdl files"page and then specify your pins function in the "signals" page, nad in your case your interupt pin. before you had to define your interupt as an output pin of your hdl component.

--- Quote End --- Hi Soin, I already added my counter component to SOPC Builder. Here is the wrapper which instantiates the task logic of counter and its interface (defining control , status , ... registers) : module counter_avalon_interface ( clk , // global signal , clk , 1bit , input reset_n , // global signal , reset , 1bit , input chipselect , // avalon_slave 0 , chipselect , 1bit , input address , // avalon_slave_0 , address , 2bit , input write , // avalon_slave_0 , write , 1bit , input writedata , // avalon_slave_0 , writedata , 8bit , input read , // avalon_slave_0 , read , 1bit , input readdata , // avalon_slave_0 , writedata , 8bit , output counter_out, // avalon_slave_0 , writedata , 8bit , export intr // avalon_slave_0 , writedata , 1bit , export ????? ); I also assigned counter_out to LED's but I am not sure of : 1) what pin I should assign intr to make CPU interrupted when it is high. 2) What I should do with my component to make it CPU-interruptable like UART , PIO , .... Have you got ideas about this ? Regards, Quan
