Is it possible to verify DCDC is working via Software testing

Dear Support Engineers

I am in the process of designing the automated testing platform for a 52832 based device and would like to test to make sure the components/devices are reflowed properly. Especially, I am concern that if L2 and L3 connected to DCC and DEC4 is not soldered on properly, we would not know as the board would just default to LDO operation. I would like to find out if it is possible to detect that the DC/DC is working properly without additional testing hardware. If this is not possible, how would you recommend the test be conducted automatically? I can think of 2 options:-

1) Having a external probe looking at DCC for buck operation waveforms as specified in the link below.

2) Measuring the current difference when transmitting with DC/DC enable and disabled.

It would seem to me that option 1 would be more complex. I am thinking of using option 2. Can you please let me know if it is possible to detect DCDC operation in software or if there is a simpler option 3 that I missed.

Best regards,

Nelson
