Hi,
how to route a Ground "plan",and the VCC "plan"?
Thanks,

You dont have to route GND/power planes. Just connect power pins to those plans using fanout commands.

You may route a Ground plane using Copper Area or Copper Pour from Obstacle Tool in Orcad Layout.

for a double sided pcb
try to avoid vias on the power and ground tracks
and if in case for routing u have to use, than better dont connect more components througt the single via or the via my get burnded and disconnect.

using protel routing is vey easy first define nets and rules then select strategy and route.
thats all

For a two layers pcb, you should have a power and ground grid, much like a chess board. This will reduce the current return path.

There is a section in book: High Speed Digital Signal Design that talks about this.

the "VCC" on the top and the ''GND" on the bottom.

I think GND need split polygon in top and bot layer
vcc need u add line of line by u manul route.

Try to make ground on bottom and VCC on TOP layer. Keep in mind that you need to use star topology to distribute POWER or ground to each element.
