    I am hoping this is in the datasheet somewhere, and i just haven't found it yet....

    How do i accurately model the load of an FPGA input pin, in this case, an Altera Cyclone II device?

    I am working on an interface from a 0.5 - 4.5V sensor to a 0 - 3.3V input pin

    I have the schematic all ready to go and simulated, i just need to ensure i am modeling the load properly.

    Any help or guidance on where to look in those ridiculously long datasheets would be appreciated.

    Have you tried contacting Altera tech support?
