I would like begin a new custom FPGA design and I am considering buying a dev kit for experimentation. When the design has finished, I intend to design a dedicated PCB board. If I change the packaging of the model and instead of a BGA move to QFP, which is easier and cheaper for me to work with, will it drastically affect my timings when I will adjust my design to it? How significant is the packaging of a FPGA related to timing for same models?
I wouldn't like to to invest a fair amount of time and money on dev kit and then find out that I don't meet the timing requirements. I know it's a little vague as a question, but I am looking to get a sense on what to expect. Thank you.
