During March 2026, Jo Wright developed Burst Equivalents for Flow Multiplexers in the xlsynth/bedrock-rtl repository, focusing on enhancing RTL reliability and data handling predictability. By ensuring that grants are held until the last signal of the granted flow is asserted, Jo’s approach prevented interleaving of multi-cycle bursts across different flows, thereby reducing cross-flow contention. This feature was implemented using SystemVerilog and leveraged skills in digital design and hardware verification. The work introduced explicit burst semantics to the flow multiplexers, resulting in more stable and maintainable FPGA designs. The depth of the solution addressed both stability and maintainability concerns.
March 2026 performance summary for xlsynth/bedrock-rtl: Delivered Burst Equivalents for Flow Multiplexers. Grants are now held until the granted flow's last signal is asserted, preventing interleaving of multi-cycle bursts across flows. This change increases stability and predictability of data handling and reduces cross-flow contention. Implemented in commit b94f9927d52af78d8d1bc69a0a39684954411575; co-authored-by Sai Ma (refs #1023).
