Mishra ji;

Thanks for clarifying the issue on hand. Problem should be tackled from both fronts i.e. Hardware (HW)as well as Software(SW). In order to make VCC and ground pin connections robust inside the silicon chip that has to be taken care of at the design steps of a silicon chip. Then when these IC are used on PCBs the VCC and GND pins connections have to be robust, however, failures do occur inspite of all these measures so design have to designed to fail to safe mode. Redundant approach is also used to minimize failues of operation i.e. if one controller or system fails other one takes control of the operation without service interruptions.

In a safety critical system " HW and SW " error detection circuits have to be carefully designed and tested to meet safety critical requirements.

I hope this helps.
