## Palette of Layers - Simulation properties

> The simulation icons add properties to the nodes. Properties are applied to the electric nodes of the circuit in order to serve as simulation guides. You must specify which node is assigned to which voltage before starting the analog simulation.

> VDD & VSS. The node is pushed to the power supply voltage with icon Vdd, and pulled to the ground 0V with icon Vss.

> CLOCK. When a node becomes a clock, the parameters of the latter are divided as follows : rise time, level one, fall time, and level zero. All values are expressed in nan-second (ns). If you ask for a second clock, the period will be multiplied by two.

> PULSE. The pulse switches from "Level 0" (0 by default) to "Level 1" (VDD by default" depending on the user-defined time table.

> SINUS. The sinusoidal waveform parameters are the amplitude, the offset, frequency and phase.

> VISIBLE NODE. Click on the "eye" and click on the existing text in the layout to make the chronograms of the node appear. Initially, all nodes are invisible, but the clocks and impulse nodes are subsequently made visible.

> Also accessible when adding a text : MATH expression. A user's defined equation may be entered to create virtually any type of waveform (such as "sin(2*pi*1e9*t)*sin(2*pi*1.45e9*t)" for example.
