Evidence and symptom review
Clarify the conditions in which the behaviour appears, review available measurements and identify which assumptions remain untested.
04 / DEBUG & INVESTIGATION
High-speed digital debug.
A structured route forward.
When a board behaves differently from the model or an interface fails intermittently, the next measurement matters. ASTRX helps structure high-speed digital hardware debug around symptoms, evidence and competing explanations.
Discuss a debug investigation ↗THE ENGINEERING QUESTION
When the failure is visible but the mechanism is unclear
A symptom can have several plausible causes across the electronic system. Changing components or layout without a hypothesis can consume time without resolving the mechanism. A structured investigation makes the next test explicit and uses its result to narrow the search.
INVESTIGATION THROUGH TO PRODUCTION
From an intermittent symptom
to a testable explanation.
Experience taking high-speed digital hardware through manufacture, verification and production informs the investigation. A marginal link or memory interface is considered alongside board implementation, power delivery and the conditions under which the symptom appears.
The investigation connects captured evidence to competing explanations, targeted checks and a proposed correction. The handover defines how to reproduce the issue and verify the change, helping the team move from a plausible fix to an evidenced design decision.
AGREE ON SCOPE / ALIGNED AROUND YOUR DESIGN
What we can investigate.
Hypotheses and targeted analysis
Develop competing explanations and use design review, modelling or simulation to choose informative measurements and controlled comparisons.
Correction and revalidation
Support a reasoned correction, document remaining uncertainties and define how to check that the change addresses the original failure mechanism.
GET STARTED
Useful inputs.
- A description of the symptom, operating conditions and reproducibility
- Relevant schematics, layout information and available design models
- Existing measurements, test methods and previous change history
- Access constraints and the decision or production milestone at risk
THE HANDOVER
Usable outputs.
- An investigation plan with prioritised hypotheses
- Recommended measurements or controlled design comparisons
- Documented findings and the evidence supporting them
- Design-correction options and a focused revalidation plan
