Assuming this is a custom slave, it has to handle the bursting correctly. Only the first address is presented in a burst. Your slave has to understand where to write the second data. Again see the Avalon spec pages 31-32.

Thanks for your guidance.

As per avalon burst write/read protocol only i am giving the inputs.Stimulus part is fine. But interconnect is not combining the input data.

My master(256bit) is narrower than slave(512bit).It should combine the two 256 bit input data and send one packet of 512 bit.

Inside the interconnect we have one module altera_merlin_width_adapter.In that PACKING(Single bit) is one parameter for that module.Now that PACKING is zero.

Is it related to my issue.Do you have any idea about that?

Thanks
