Extending the Open Model Interface API to Update Parameters at Every Timestep of a Transient Simulation
Bibliographic record
Abstract
We propose an extension of the Open Model Interface (OMI) API standard that allows to update the model and/or instance parameters of supported compact models at every timestep of a transient simulation. This can be used to make the model behavior dependent on bias conditions and/or device history. One potential application of this method is the modeling of random telegraph noise (RTN). In order to investigate the limitations of the approach in terms of accuracy, stability and simulation runtime, we use it here to add self-heating to a bsim4 model in our in-house simulator. This test case is chosen because an alternative implementation with a thermal subcircuit is available as reference. Our tests show that a mechanism to limit the maximum timestep is required to ensure stability and sufficient accuracy of the simulation results, and this is included in the proposal.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
