pin compatibility of FPGA with same number of pins

hello, i am currently using EP3C16F484 in my project, and now i want to upgrade to EP3C40F484, need i design again the schematics and relayout the PCB? or i can directly use a EP3C40F484 to solder...

You can use the EP3C40 in place of EP3C16 if migration compatibiltiy has been beared in mind during pin placement. See the migration devices setting in Quartus assignments.

thanks for your replying.

so you mean that the funtion of some pins between these two devices is incompatible, if i used one of these pins in 3C16, it could not be replaced by 3C40 without redesigning.
