I'm using v19.1 to generate the Avalon-MM intel Startix 10 Hard IP+ example design by using the default setting, but I can't see the same error.
- How do you configure the IP? Does using default settings also having the same issue?
- What is the OPN (Device's full name)?
This problem may only happen in certain PC or OS. For a quick workaround, I have helped to generate the design and attached it here for your reference.
