Ris/fall time?

Hello, I am developing a simple test board for a cyclone FPGA (EP2C8T144). It is my very first FPGA project, and I want to build my own FPGA board. Now, my question is: Which rise and fall...

Hello OrchestraDirector,

thanks for your answer. The device which I am driving with the FPGA is an ARM7 microcontroller (the FPGA is attached to the micro's memory bus).

How long can I make the trace length, if I don't put any resistors in the tracks? Longest track is ~25 mm. Will this work if I program driver strength to minimum? I don't need very fast I/O (I'm working with low frequencies).
