Difference between a power and signal pin?

Hi,

I am making a schematic on virtuoso.

What difference will it make if I use a signal pin instead of a power pin for VDD (when choosing the signal type for the pin)?

Thanks and regards,

Vishesh

In manual flows, it typically doesn't matter. It is more important for place and route flows (e.g. if you're using the Virtuoso Space-Based Router, or using LEF/DEF or Innovus flows) as typically these have specialised routers for power/ground and (for example) clocks. The signal type is typically used to identify such special types of nets in those flows.
