Hi
1 top +signal1
2 GND
3 Signal2
4 signal3
5 PWR
6 Bottom + signal4
The above stackup will give micro stripline and Dual strip line.
Use high speed signals in signal1 and signal2, so that GND reference will be
there.
Take care the parallel crosstalk in Signal2 & Signal3. Also Power plane
coupling is not more effective.
I guess the above it best.
If you go with below stackup, you may need to use more thick trace to achieve
the impedance in TOP and BOTTOM layers.
Also you need to take care S1 & S2 crosstalk and S3&S4 crosstalk (parallelism)

Karthik

Subject: [SI-LIST] 6 layer board stack up
Dear signal integrity experts
What is the best way to stack up 6 layer board that has 4 signal layer and one
power plane and one ground layer?
I know there are lot of factors involved but what is a good stating point to
stack them and simulate it. Is there any literature or paper that provides any
guide?
For example does S1,S2,P,G, S3, S4 a good starting point(S-signal layer,
P=Power plane and G=ground plane)?
Many thanks in advance for your advise.
Regards;
Don Pakbaz
