Hello everybody, I'm a trainee in digital electronics, i should achieve a migration of VHDL codes from the Digilent Nexys 2 which is obsolete to another board, after some researches, I would like to work with the Nexys4DDR board. However, there is a problem of the number of connectors in the Nexys4DDR, in my project, I need at least 40 pins for my signals, it was possible with the Nexys2 thanks to the Hirose FX2 connector which disappears in the new Nexy boards. Should I choose another FPGA board or add an expansion to the Nexys4? In the last case, will there be synchronization problems?
