* Configuring the gateware with more lanes for the RTIO core reduces the frequency of sequence errors. * Configuring the gateware with more lanes for the RTIO core reduces the frequency of sequence errors.
* The number of lanes is a hard limit on the number of simultaneous RTIO output events.
* Whether a particular sequence of timestamps causes a sequence error or not is fully deterministic (starting from a known RTIO state, e.g. after a reset). Adding a constant offset to the whole sequence does not affect the result. * Whether a particular sequence of timestamps causes a sequence error or not is fully deterministic (starting from a known RTIO state, e.g. after a reset).
