The task

Write /app/dut.sv defining TopModule with ports clk, rst, psel, penable, pwrite, paddr[3:0], pwdata[31:0], prdata[31:0], pready, and pslverr. rst is synchronous active high. The master uses APB setup then access: setup has psel=1, penable=0; access has psel=1, penable=1 with address, write bit, and data held stable. Only access cycles can complete transfers. While rst is high, clear writable registers and drive prea…

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

10 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.
