• ASM-HEMT GaN model

The strategy files encode triggers, prerequisites, parameter dependencies, phase order, physical constraints, validation criteria, and corrective actions for a model family. They do not store expert-extracted final parameter values. Initial values must be estimated from the target device measurements or chosen from justified physical ranges.

Adapt parameter names and available mechanisms to the installed compact-model version and the measurement set.

Extraction loop

1. Identify the model family, characterization domain, and available data.
2. Check project and data prerequisites.
3. Select the smallest parameter group identified by the current domain.
4. Estimate starting values from the target measurements.
5. Apply physically meaningful bounds.
6. Simulate and inspect the initial state.
7. Optimize the active group through IC-CAP.
8. Evaluate numerical error, curve shape, and physical plausibility.
9. Apply a targeted corrective action when the phase is not acceptable.
10. Recheck earlier domains before moving to the next phase.

Parameter extraction is not a single optimizer call. Project construction, data preparation, phase order, parameter coupling, physical constraints, and cross-domain evaluation all affect the accepted result.
