generate waveform output on FPGA from file

I have a testbench that generates inputs to my module. It works in simulation. What I want to do is take the waveform of these inputs (5 of them, each is just 1 bit) and put those an on FPGA that out...

Depending on the size of your stimulous waveforms, the easiest way is to just set them up as a ROM in the FPGA, and have a simple state machine that addresses the rom to drive the outputs. I wouldn't bother with the SDRAM unless the size of the files are larger than what will fit into the internal rams of the FPGA.
