Title: Difference between voltage and electrical
Post by neoflash on Nov 18th, 2006, 7:13am

Some coder directly declare signal as voltage instead of electrical, what is the difference?

Can we also declare current type signal?

Yes.  These are known as "signal flow disciplines" and I think they're used when you don't care to enforce KCL and KVL, you are just propagating a value.  Some simulators may be able to simulate this more efficiently.  I haven't used this capability myself.
