High currents at input pins

Hi All, 

 

I´m using a EPM 1270 TQFP. The problem is, that the part is drawing a lot of current at the input pins. All is working, but at my resistors I can see a high voltage drop. How can I activate buffers or how can I activate the Schmitt trigger for the inputs? 

I´m using Quartus II for programming and schematic drawing. 

VCC is 3.3V

What's "a lot of current"? Can you be more specific?  

 

Unless weak pull-up resistors are activated, the inputs can be expected to show high impedance. If you observe something different, you probably assigned wrong pins.
