1.6 PSL logic signals properties
The logic signal toolbar is used to select logic signals.
Right-click any logic signal and select Properties… This opens the Component Properties
window. The format varies according to the logic signal selected.
Properties of each logic signal, including the Component Properties windows, are shown in
the following sub-sections.
1.6.1 Link properties
Links form the logical link between the output of a signal, gate or condition and the input to
any element.
Any link that is connected to the input of a gate can be inverted via its properties window. An
inverted link is indicated with a “bubble” on the input to the gate. It is not possible to invert a
link that is not connected to the input of a gate.
