Validators provide the critical function of objective design evaluation:
Functional Verification: Using Verilator, validators simulate designs against comprehensive test suites containing millions of instructions. Results are compared against golden references to determine functional correctness.
Synthesis Analysis: Employing Yosys and OpenLane, validators synthesize designs to gate-level netlists, extracting accurate area metrics and timing characteristics.
Score Calculation: Combining individual metrics using challenge-specific weights to generate overall scores that reflect the relative importance of different optimization objectives.
