Not videos. Not slides. Every module is a working interactive reference built from real engineering practice — the same decision framework taught in our live HyperLynx/Ansys SIwave cohorts, now self-paced.

Every module builds the engineering judgment behind the simulation — model selection, corner conditions, root cause reasoning — not just which menu to open. Ansys SIwave and HyperLynx workflows are shown as demonstrations of applying the framework.
Every workflow starts with power validation, because a PDN result is a physical dependency of every signal result — not a convention. You'll never analyze SI on an unvalidated PDN again.
Each module ends with a stated, derived, and applied decision rule — the kind you can defend in a real design review, not just recite.
