Hi,

Actually just now i did not set the associated addressable interface parameter of the interrupt sender. That is what causing the errors. But I still having warning as follows: 


Warning: counter_0.irq: Interface has no signals
Warning: counter_0.irq: Master has no read or write interface
Warning: counter_0.interrupt_handler: readdata width must be in {8, 16, 32, 64, 128, 256, 512, 1024} for dynamic addressing
Warning: counter_0.interrupt_handler: writedata width must be in {8, 16, 32, 64, 128, 256, 512, 1024} for dynamic addressing

Is the warning have to be considered or can be ignored?
