It may not be as much work as you expect.
If they don't have what you want in a library (and it wouldn't suprise
me if they do, though I don't specifically recall one), you could
certainly piece it together from what is in the library.
It can be done as a schematic (schematic capture/entry) so you
don't need to learn an HDL
The work would be in installing and learning the design software
well enough to get the design in and program the device (not hard) and
arranging hardware to actually program the part (a simple parallel port
interface similar in complexity and function to a Xx1541 cable)
