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 on the die of EP3C16F484 on the board. 

i hear that altera fpga is pin compatible with same number of pins, but i am not sure. 

 

thanks.

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.

Select the device you want migrate to in Quartus device settings. 

Then go to pin planner and select "Pin migration view" in the view menu. Here you will see the pinout of the fpga devices and you can highlight the differences. 

Good luck!
