<GitHub-m-labs> [artiq] sbourdeauducq commented on issue #1171: Agreed. If no one objects, I'll add ``archive`` to ``set_dataset`` while keeping ``save`` (for backward compatibility and with a warning; we can e.g. do that in 4.0 and remove it completely in 5.0). https://github.com/m-labs/artiq/issues/1171#issuecomment-428406885

<GitHub-m-labs> [artiq] jordens commented on issue #1173: IIRC this was discussed from multiple perspectives. The rule AFAIR is that APIs that are either intrinsically `parallel`-izable with other APIs that use the same resources (by virtue of having zero length, setting an idempotent state in a single RTIO cycle, typically also replaceable) or have some parallelism support with other APIs using the same resources (e.g. throug

<GitHub-m-labs> [artiq] sbourdeauducq commented on issue #1173: The problems with the AD9914 parallel bus are the same as with the AD9910 serial bus, except that transfers take longer to complete with the latter. The Urukul is just as batch-compatible as the NIST AD9914 hardware.... https://github.com/m-labs/artiq/issues/1173#issuecomment-428579832
<GitHub-m-labs> [artiq] jordens commented on issue #1173: AFAICT the reason for the API difference is not the feasibility of implementing batching but the fact that batching was implemented for AD9914 (hence the adherence to the preivous zero-duration `set()`) while it wasn't and isn't implemented for Urukul. That makes the ad9914 driver a bit tedious to use since batching was completely removed.... https://github.com/m-la
<GitHub-m-labs> [artiq] jbqubit commented on issue #1174: When operating AD9910 in Single Tone Mode there are 8 independent Profiles. Set PROFILE[2:0] to select the desired profile. A change in the state of the profile pins with the next rising edge on SYNC_CLK updates the DDS with the parameters specified by the selected profile.... https://github.com/m-labs/artiq/issues/1174#issuecomment-428622299
