Abstract
We present an automated framework for the validation of memory controllers (MCs) called MCXplore. In developing this framework, we construct formal models for memory requests and command interactions. MCXplore enables validation engineers to define their test plans precisely using temporal logic specifications. We use the NuSMV model-checker to generate counterexamples that serve as test templates. MCXplore uses these test templates to generate memory tests to validate the correctness properties of the MC. We show the effectiveness of MCXplore by validating various state-of-the-art MC features as well as hard-to-detect timing violations. We also provide a set of predefined test plans, and regression test suites that validate essential properties of modern MCs. MCXplore is an open-source framework to allow validation engineers and researchers to extend and use.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
