Hey everyone,
First off, any help would be greatly appreciated and thank you to anyone who does respond.
I have a large design that uses a single VDD and VSS throughout, except for a single small portion that needs to be supplied by a separate power source. The portion includes about 45 standard cells and a memory macro that will need their power pins attached to a different power supply that is given by a single pad's signal. I have found some documentation on voltage islands, but I haven't been able to discern exactly how to apply it to my very simple design. If you have done this or know how to, please HELP.
thanks
