Examples with DataBus de.neemann.digital.core.wiring.bus.DataBus used on opensource projects

Example 1 with DataBus

use of de.neemann.digital.core.wiring.bus.DataBus in project Digital by hneemann.

the class DataBusTest method testSimple.

public void testSimple() throws PinException, NodeException {
    ObservableValue a = new ObservableValue("a", 4).setToHighZ();
    ObservableValue b = new ObservableValue("b", 4).setToHighZ();
    Model m = new Model();
    ObservableValue out = new DataBus(null, m, a, b).getReadableOutput();
    a.setValue(1);
    assertEquals(1, out.getValue());
    a.setToHighZ();
    b.setValue(2);
    assertEquals(2, out.getValue());
    b.setToHighZ();
    // try {  ToDo HighZ
    // out.getValue();
    // assertTrue(false);
    // } catch (HighZException e) {
    // assertTrue(true);
    // }
    a.setValue(1);
    b.setValue(1);
    m.doStep();
    a.setValue(0);
    b.setValue(0);
    m.doStep();
    a.setValue(1);
    b.setValue(0);
    try {
        m.doStep();
        assertTrue(true);
    } catch (BurnException e) {
        assertTrue(true);
    }
}

Example 2 with DataBus

use of de.neemann.digital.core.wiring.bus.DataBus in project Digital by hneemann.

the class Net method interconnect.

/**
 * Do the interconnection.
 * All inputs and outputs in the net are connected together.
 * If there is no output an exception is thrown.
 * If there is one single output, all input {@link ObservableValue}s are set to this output
 * If there are more then one output a {@link DataBus} is created.
 * <p>
 * At the end all wires get a reference to the {@link ObservableValue} the represent
 *
 * @param m           the model is needed to create the {@link DataBus}
 * @param attachWires if true, the values are attached to the wires
 * @throws PinException PinException
