Yes,you can divide power plane for the three different voltage. but be careful, especially for rocketI/O 's power.
of course , it will be better, you assign different voltage power on different layers.
If using RocketI/O ,you can refer to xilinx RocketI/O user guide for power layout.

Yes.
you can try FPGA editor,you can manually place and route your trace.but it take too much time.
you can automatically palce & route first
and modify the trace or component(LUT, ...)manually
yes ofcourse you can not use specman without license which is very expensive.
and as I known , it is possible to use speman for learning purpose in university only.
Just as ram said , specman is too expensive , but it is a very great tool.
our boss decide to not purchase specman license any longer next year.
HHH
we will have to use other ...to do verification work
may be systemC

how many TBUF you have used?
did you open your design with FPGA EDITOR to see whether it is true that there is no more TBUF to be placed .
moreover, XC2V1000-4 support TBUF or not?
How could I do?
Can you describe your problems detailedly?
Whch product and which version synplicityyou are using? do you man synplify?
Are you using Quartus or QuartusII
If you you can describe you question more detailed, others can help you more
