[SI-LIST] Re: Address bus simulation

I fully agree with the previous recommendations to use some sort of bit
pattern other than alternating H-L-H-L-...

But first of all, you MUST understand what your signals are supposed to
look like.  Whether they represent an address bus, data bus, control
signal, or clock ... makes no difference.

If the clock rate is 200MHz, can the signal change every 5ns?  2.5ns?
10ns?  It makes no sense at all to simulate an address bus using a
200MHz square wave when the address can change at best only every 5ns.
A 100MHz square wave would approximate the alternating 1's and 0's case,
i.e. highest fundamental frequency, but this is only one picture and not
the whole story.  I'd go for the pseudo random bit pattern, or a bit
pattern with some sequences that cause interesting effects.  Some 010101
and some 00110011 and 00001111 and 000010000 and 111101111, etc.
