    Hi there,

    I have to route a 6 layers board by using the "Altium Designer 10" software.

    Since it's the first time that I'm working with the multilayer technique I found a lot of problems:

    First, in my board I use 3 powers : 1.2V, 1.8V and 3.3 V. Can I split the 3 powers into 1 power plane? If yes, how can I divide the 3 regions ( What's the considerations that I should take when I will split the plane power?)

    Sencond,in this board we have a DSP with the frequency of 600 MHz and 2 DDR; I want to know if I have to take precautions about the signal integrity, if yes what's these precautions?

    Finally, how can I chose the width value of tracks and the vias value between layers?

    I know that I asked a lot of questions, but I feel that I'm a little blocked.

    Any help will be appreciated...

    In Altium designer you have something named Polygon Pours and Copper Regions
    Depending on the design you may perhaps use 1 layer as a ground plan. And one layer for the 3 power plans. Then you have 4 routing layers.
    I see you more questions but let us take them later
