A crosstalk report lists victims, their aggressors, the coupling and the delay change each causes. Reading it quickly and critically is a signoff skill: you need to know what the filters removed, which aggressors cannot really switch together, and what has to be true before SI is called closed. This topic covers the report format, filters and windows, false aggressors, and the signoff checklist.
Lesson | After it you can... |
|---|---|
Check a victim's total against its aggressor lines. | |
Understand what filters hide and what they cost. | |
Reduce pessimism from exclusive aggressors with evidence. | |
Decide whether SI is ready for signoff. |
The victim's total delta and the sum of its counted aggressor deltas: a mismatch means that an aggressor is hidden by a filter or the report counts differently.
