Hi everyone! I’m currently diving into AXI4 as part of a design exercise, and I’m looking for some advice on how to build a better intuition for the protocol. While the spec is very detailed,.. I sometimes find it challenging to visualize the VALID/READY handshake in practice, especially on channels like Write Response (B channel), where the flow feels a bit less intuitive compared to the main data channels.
For those of you who work with AXI in real-world designs, I’d love to hear what helped you the most when you were starting out. did you find it more effective to sttictly follow timing diagrams, or was it more about building small test cases and observing the behavior in a simulator??? I’m trying to find a practical way to approach the protocol without getting completely overwhelmed by the full specification. my goal is to move past just 'making it work' and actually understand the underlying design logic. Any tips or learning strategies would be greatly appreciated. Thanks!
I’ve been reading through the AMBA AXI4 Specification (IHI0022) and the Introduction to AMBA AXI guide, specifically the sections on channel dependencies. However, seeing the handshake in a live simulation feels different from reading the tables
