Hi guys!
I am currently working on a mixed signal project in research. I am at the beginning of my PhD and am working on an institute where a lot of analog knowhow is present. but only minimal digital. This is my topic.
While I am able to create digital design blocks in innovus, the know how how to implement everything is a little lacking. So my question is:
How to handle ground and vdd connections?
What I have thought was to have the digital VSS net, the analog VSS net and the VSS net for IOs....those will be only connected on PCB quite next to the ASIC. I think this is needed to not eintroduce the ground bounce created from the digital circuit to the analog, and not to connect the groudn bounce from the IO drivers to anything at all...
VDD nets are also seperate, I plan to seperate them on the PCB as well.
How to do it properly?
THank you a lot and have a nice day!
