Partially disagree with mishrashashi.
Using power plane as return path is same as using ground plane. I don't see why there will be more signal integrity issues (reflection noise, crosstalk,emi/emc) versus ground plane.
Does anyone know where to find the definition of Hyperlynx schematic syntax?
What I learned is that it's not backward compatible. For example, a schematic file (.ffs) from Hyperlynx v7 won't be recognized by v6. The crazy thing is it seems Hyperlynx v7 won't save in v6 format either?! Wish I am...
Re: Imaginary numbers
Imaginary number/axis is an invention by mathematician. They played with it and found good usage of it, such as for electrical signals. It does not apply well with the "person walk" example you described. But if you swap person with periodic or repetitive electrical...
Re: Imaginary impedance
I agree mostly except the last part starting from total impedance. There is no mentioning about how overall network is consist of. So, the total impedance is kind of misleading since "total" is undefined. I would suggest mentioning individual impedance of C and L. Also...
