Upgrading SDK software version from 2.5.0 to 2.6.0#
Version 2.6.0 made a change in the way in the way that flattop waveforms get constructed.
Previously, a flattop was created by first making a waveform that represented the rising and falling portions.
Then, when the to_flattop method was called, the waveform would “split” in half and a hold would be placed
in between the rising and falling portions.
Now both of these steps are done with one call to either DCWaveform.create_dc_flattop or RFWaveform.create_rf_flattop.
This comes with the additional benefit of being able to control the rising and falling times independently
