Assuming you have a bunch of voltage waveforms, one for each bit, then this is what you do:

1. Plot all the voltage waveforms, and then select them all.
2. Select the a2dDialog icon
3. On the form that pops up, you can then enter the thresholds for converting these to digital signals (either a single threshold or a high/low threshold). You can choose where to plot the new signals.
4. Having got your new digital signals, you can select them and convert them to a bus. You may want to drag them around first so they're in the right order, or use ctrl-select to select them one at a time in the right order. Then use the Create Bus Icon.
5. A form will appear (you'll probably want to expand it, and drag the signal column to be wider, so you can see which bit is which) and click on the Bit column if the bus is in the wrong order. Choose the radix you want, and where to plot it, and hit OK.
6. You can then do fun things like select the resulting bus, and convert it back to Analog (using Busses output as Analog Voltage) so you can see an analog representation of the bus waveform.

Ken,

Well, if converting a set of bits into a bus, then this is just representing it as a simple bus - not doing any encoding. I was assuming that was what was wanted here.

That probably doesn't matter, unless you're trying to then represent that bus as an analog waveform (step 6 in my previous post) - for thermometer coding that wouldn't be terribly useful.

Andrew.

Hi, Andrew,

Thank you. I did it as what you said. It's easy to use.
