The task

Mesh network-on-chip router: virtual channels, credit flow control, wormhole switching Write the router of a 4x4 mesh network-on-chip in synthesizable Verilog/SystemVerilog. The grader instantiates 16 copies of your router module, wires them into a 4x4 mesh and drives traffic into every node. On every link, every cycle, it checks the flow-control protocol, the routing and every flit. It also runs performance tests w…

Results by model and effort

This exact task version only. Every rate is passes / valid runs with a Wilson 95% interval; n≤2 remains counts only. Macro aggregation does not apply within a single task. Baselines are summarized in the quality gates, not ranked. A passed no-op resistance check means that doing nothing did not solve the task.

Every recorded run

5 recorded trials, including controls. Diagnostic labels do not replace verifier reward. Labels and quality checks are source declarations, not independently attested here. Internal evidence remains private; a missing public URL is shown explicitly. Records with invalid or absent rewards are not scored.
