public class LUT1Example {

    public static void main(String[] args) {
        Design design = new Design("example", "xcvu3p-ffvc1517-1-i");
        Cell cell = design.createAndPlaceCell("lut1", Unisim.LUT1, "SLICE_X18Y31/A6LUT");
        cell.addProperty("INIT", "O=I0");
        Net net = design.createNet("net0");
        net.connect(cell, "O");
        net.connect(cell, "I0");
        // By default, it will use the A_O output pin, so we'll remove it and use AMUX
        // instead to force the use of OUTMUXA
        net.removeSource();
        SitePinInst outputPin = net.createPin("AMUX", cell.getSiteInst());
        BELPin lutOutput = cell.getBEL().getPin("O6");
        // Route the intra-site connection
        cell.getSiteInst().routeIntraSiteNet(net, lutOutput, outputPin.getBELPin());
        // Route the inter-site connection
        RWRoute.routeDesignFullNonTimingDriven(design);
        design.writeCheckpoint("example.dcp");
    }
}

This will force the use of the OUTMUX as shown in this routed view in Vivado:

Whether it means I need connect the cell and sitepin while create a cell instance!
