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?

 

i have not yet, but thats a really obvious/good idea that i really should have already done before posting here.


im pretty dumb sometimes.
