Bug fix for Quartus 13 .0 or 13.0 sp1 that fixes OR gates acting like AND gates and AND gates acting like OR gates

HI, Im using a RioRand and discovered that when I OR 2 signals either in VHDL or schematic they act like an AND gate and ANDing 2 signals acts like an OR gate. IS there a fix for this?

Hi Daryl,

Your Led's are active low based on schematic.

Based on your post, Switch should be implemented as active low.

Which will lead you to interpret AND gate as OR gate.
