Description
Eye diagrams have been discussed in previous SpaceWire WG meetings and in the frame of the revision process of the ECSS-E-ST-50-12C as possible requirements for the validation of SpW implementations. Examples of Eye diagram measurements performed on two different test set-ups (one using a GR712 development board from Cobham Gaisler AB and one based on Protocol Validation System of Teletel SA) will be presented and some related issues ( oscilloscope and probe bandwidth, definition of “clock” for eye diagram on SpW, eye masks , testing of SpW at closed box….) reported. Ideas for the validation flow of the Physical layer of a generic SpW implementation will be presented
