<!-- Define a circuit model for the standard cell MUX2
OpenFPGA requires the following truth table for the MUX2
When the select signal sel is enabled, the first input, i.e., in0
will be propagated to the output, i.e., out
If your standard cell provider does not offer the exact truth table,
you can simply swap the inputs as shown in the example below
