now i decided to make 4layer pcb for ep2c20f256 ep2c8f256 and ep2c5f256 insted of 8layer pcb for ep2c20;35;50 in fbga484 package becose its to expensive and i dont now how big device i will need, so a good starting point would be ep2c20 in smaler fbga 256 package.

as i already have routed in 2 layers ep2c20f256 device then i will need to add ground planes and vcc int,i/o plane.

how much layers these small fpgas need 4 or 6 ?

if i will need in future larger device then i will make pcb for fbga672 package becose it covers larger devices than fbga484.

wen i will route mu nev 4 layer or 6 layer pcb the i will post link to pictures.
