Function analog_int_netlist_from_source 

pub fn analog_int_netlist_from_source(
    src: &str,
    fn_name: &str,
    target: &AnalogTarget,
) -> Result<AnalogNetlist, AnaLowerError>

Lower an INTEGER function to an analog tile netlist realizable on target. The exactness claim itself is made downstream by super::exactness_gate over the scheduled budget.
