What protocols does the SimDDR Backend Dev skill support?

It specifically supports AXI3, AXI4, and custom bus variants, focusing on burst splitting, interleaving, and data width configurations.

Can this skill help with performance benchmarking?

Yes, it includes workflows for running regressions with standard benchmarks such as CoreMark, Dhrystone, and Linux smoke tests to verify backend stability.

What is the primary benefit of the two-phase modeling suggested?

It prevents race conditions in the simulator and ensures that signals like 'ready' and 'valid' are sampled and updated in the correct clock cycles.

How does this skill improve simulation accuracy?

It enforces a two-phase (comb/seq) logic separation, ensuring that combinatorial outputs and sequential state updates mirror real hardware behavior.

Streamlines the implementation and refactoring of memory backends and AXI interconnects for RISC-V simulators.

The SimDDR Backend Development skill provides a specialized workflow for engineers working on hardware simulation environments. It offers structured guidance for adding or refactoring SimDDR and interconnect backends, specifically focusing on AXI3, AXI4, and custom bus variants. By enforcing a two-phase combinatorial/sequential modeling approach, the skill ensures accurate timing for handshake signals, backpressure, and burst transactions, while providing a framework for rigorous unit testing and performance regressions using benchmarks like CoreMark and Dhrystone.
