Very half-baked idea!
Example application: adding a noise figure to AnalogLink ports and having noise-aware analog devices propagate noise figures. For example, characterizing the noise on the SMU through the measurement chain.
Example application worked out:
- The noise chain is initialized at the measurement input with zero noise
- Opamps that are noise-aware might:
- On analog inputs that don't support noise: either: materialize zero noise, or don't generate a noise output
- Add the input noise to the device noise to the output
- Wrappers (eg, Diffamp) would need to account (somehow) for how it transforms noise - possibly by adapting the input and output noise parameters
- Opamps that are not noise aware would ignore noise on the input ports (they break the noise chain)
- Wrappers should be smart about propagating noise ... somehow?
Need to figure out how this interacts with the compiler dependency-graph (when generators know when ports are noise-aware). This makes structural port definitions that were previously static more dynamic, much like port-arrays.
