[Dsg-rich] [EXTERNAL] meeting with DSG

[Valery Kubarovsky]

Hi Marco,
I don’t think that it is a good idea to keep both compressors work all the time.
The compressors are very expansive and have limited time resource.
Regards,
Valery

Hi Tyler,
thank you for the minutes, just one clarification.
The system should have both compressors working together routinely, and,
ideally, in case of failure of one compressor, the second should be able
to supply both RICHs for short periods, until the broken one is
repaired.
Best regards,
Marco

Hi Marco,
  Regarding the FPGA temperatures, since we don't have the FPGA code
itself we can only make an educated guess, but it's quite likely that
it is using the on-die temperature sensor.

  Note that this sensor has an error of +/- 4C when the temp is < 100C
