Eclipse Community Forums[Model Semantics] how dataRates relate to frequency domain
https://www.eclipse.org/forums/index.php/mv/msg/1103772/1827379/#msg_1827379
Extremely exaggerated example:
FreqencyDomain is 10Hz, DataRate is 200Bit/sec, and we transmit 150 Bit. Should the transfer end after 0.75 seconds or ceiled to 0.8 seconds (next clock edge) ?
The Access/Read/Write Latencies are related to the actual frequency and use an IDiscreteValueDeviation, with the same logic the above example would be 0.8 seconds.

good question. It is not clearly specified in the documentation, I would recommend to do it in the same way like we do it for the latencies and relate it to the actual frequency of the component. In general I think for higher frequencies the difference is very small of even negligible. For smaller frequencies it is more important.
I also would like to mention that it is slightly different for HwConnections compared to modules like Memory, PU, etc. The HwConnection doesn't have a direct frequency domain reference. In this case the following rule applies (copied out of the documentation):
"the frequency is always provided by the element which is in front of the HwConnection in the HwAccessPath" --> e.g. The ConnectionHandler for the HwConnection which connects the ConnectionHandler with the Memory.
