How the Signal Routing Block Works
The Signal Routing Block has 8 outputs (I0 - I7). Each output uses a 16:1 multiplexer that connects to
16 inputs.
The Signal Routing Block has more than 16 input signals, so not every input can be connected to every one of signals I0 -
I7. However, signals I0 - I7 are functionally identical, so connecting to a specific one isn’t important. If you can’t route the
input with your first choice, simply choose another.
The Lookup Table lets you connect any input signal I0-I7 to any Lookup Table output signal Q0-Q17
You can manipulate your inputs using simple or complex Boolean expressions. The following expressions are both valid:
Q0 = I6
Q6 = !(I4 & I6) & ((I2 ^ I5) | I1)
