I am looking to Convert a Pulse Train w/ both positive and negative pulses into a suitable form to be used by an FPGA board. I have to also keep track whether the pulse was positive or negative.

If you could provide a diagram of what you are trying to capture, we might be able to better assist you. Just right of the bat though, it seems like you will need a state machine to process the incoming data.
Also, what exactly do you mean by negative pulses. Applying an actual "negative" voltage to the FPGA pins will damage the device.
