<GitHub-m-labs> [artiq] sbourdeauducq commented on pull request #1136 906fe3c: ``reset()`` already does ``break_realtime()``. https://github.com/m-labs/artiq/pull/1136#discussion_r213199595
<GitHub-m-labs> [artiq] sbourdeauducq commented on pull request #1136 906fe3c: PulseNotReceived? https://github.com/m-labs/artiq/pull/1136#discussion_r213199799

<GitHub-m-labs> [artiq] sbourdeauducq commented on pull request #1136 906fe3c: What about IncorrectPulseTiming? https://github.com/m-labs/artiq/pull/1136#discussion_r213204941
<GitHub-m-labs> [artiq] sbourdeauducq commented on pull request #1136 906fe3c: Right now there is an uncompensated latency offset between the gate and the input. So, the received timestamps can be slightly outside the gate. This offset also causes the pulse not to be received above. https://github.com/m-labs/artiq/pull/1136#discussion_r213206607
<GitHub-m-labs> [artiq] sbourdeauducq commented on pull request #1136 906fe3c: ``+ 3*8`` compensates for latency offset (then the pulse arrives in the middle of the gate). https://github.com/m-labs/artiq/pull/1136#discussion_r213207333

<hartytp> do you foresee any problems with that?

<larsc> hartytp: In case you are here and just invisible. I don't now why certain DACs are just 14-bit. But all the new JESD204 DACs are 16-bit
<GitHub-m-labs> [artiq] jordens commented on issue #1139: They are used quite a bit. What complexity and bugs are you referring to? https://github.com/m-labs/artiq/issues/1139#issuecomment-416628434
<GitHub-m-labs> [artiq] cjbe commented on issue #1139: @sbourdeauducq we also find aliases handy, and use them quite a lot. https://github.com/m-labs/artiq/issues/1139#issuecomment-416634084

<GitHub-m-labs> [artiq] k-beck commented on issue #1139: I agree with @cjbe -- we use aliases within the device database to abstract physical channels (ex: digital channel 3) with their functional names (ex: line trigger input), while maintaining the ability to use either. https://github.com/m-labs/artiq/issues/1139#issuecomment-416645244
