Hi,
I'm doing the Layout of an analog circuit with 2 power domain VDD=1.8V and VCC=3.3V. Both have the same ground = 0V.
My question is: - is it better, in the layout of the ASIC to separate both ground in the ASIC, even if there are connected on the PCB outside and they share the same subtract (As it's done to separate digital and analog part)
- Or at the contrary it is better to physically connect both ground in the ASIC with metal ??
What is the best and why ?
Thanks!
Ivory
