When it comes to digital circuits, it is often important to get certain internal design signals to an I/O pin and then view it on scope. This is in-spite of all the other techniques that exist to debug such designs. We could get the signal onto an oscilloscope or logic analyser.
If one wants to include a special connector dedicated to this purpose, what options exist? This would be a connector with a small form factor that can be easily connected to logic analyser or oscilloscope probe.
Edit: Please assume that I need 16-20 pins to be dedicated to this purpose and since it is for an FPGA, it is going to be for digital circuits
