Abstract
This work presents an automated framework for the validation of dynamic random access memory controllers (DRAM MCs) called MCXplore. In developing this framework, we construct formal models for memory requests interrelation and DRAM command interaction. The framework enables validation engineers to define their test plans precisely as temporal logic specifications. We use the NuSMV model-checker to generate counter-examples that serve as test templates; hence, MCXplore uses these test templates to generate memory tests to validate the correctness properties of the memory controller. We show the effectiveness of MCXplore by validating various state-of-the-art MC features as well as hard-to-detect timing violations that often occur. We also provide a set of predefined test plans, and regression tests that validate essential properties of modern DRAM MCs. We release MCXplore as 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
