Honored ContributorIn the "Interfaces" tab, go to your avalon_slave_0 interface and look for the "Pipelined transfers" part. There replace the 0 in "Maximum pending read transactions" with the highest number of transactions you can hold in your pipeline.

Super ContributorProbably would be better to create a new thread instead of reopening one from 13 years ago.
In any case, how are you coding the signal in your custom component? And you must be using pipelined transfers with variable latency: https://www.intel.com/content/www/us/en/docs/programmable/683091/22-3/pipelined-read-transfer-with-variable.html
