Describes how specific electrical-type (PE) atomic components can be
vectorized.
A vectorized component is replaced with N (bus size) instances of the same
component on compilation, where N is defined by the bus it is connected to, or by
the value of its mask properties. On Figure 1 a
vectorized inductor L of size N = 3 is depicted on (a). Once the
compilation/validation starts, the inductor is replaced (internally, the schematic is
not changed) with 3 separate "scalar" inductors (b) named L(1-3).Figure 1. Representation of a vectorized inductor
The values of the properties of those new inductors depend on how the original
vectorized inductor was defined. Consider the example in Figure 2. All
properties in (a) are defined as scalars, while the Inductance
property in (b) is defined as a vector (Python list). In case (a), the inductor will be
vectorized only if connected to a bus (it also inherits the bus size), and the resulting
scalar inductors will have their properties equal to the original inductor. In case (b),
the three resulting inductors have their Inductance property set
as 1e-3, 2e-3 and 1e-3 (in order), and their Initial
current as 1.
Using a list format on property values forces N to be equal to the size of the
list, which means a connected bus must be of the same size, as well as lists entered in
other properties, otherwise the validation will fail with a dimension mismatch error.

Simple
example
Consider the small circuit in Figure 3. The size N=3 is defined on each component as follows:
Vs1: directly by the Phase property
IR1 and IR2: the bus size is inherited from connected components
R1: directly by the Resistance property
R2: since the Resistance property is a scalar, the size is inherited
from connected components
Figure 3. Simple example - schematic and property values
With this parametrization, the Vs1 source becomes effectively a
three-phase sinusoidal source. The waveforms of the current measurements, which can be
seen in Figure 4,
show the phase delay between the currents. The different resistance values on each phase
of the R1 resistor produce currents of different amplitudes, while R2
maintains the same value across phases.Figure 4. Simple example - current waveforms
