Plot
The effective impedance that the Altera device encounters is shown in ( Figure 1–12 ).
Other information, such as Z
TARGET
and F
EFFECTIVE
are also shown in the plot, along
with the impedance profile of components such as capacitors, VRM, and BGA via,
within the PDN system. The plot is updated automatically when related parameters
are changed.
As provided in other tabs, you can save and restore the final capacitor count and other
settings for a specific set of assumptions. There is also flexibility to revert back to
default settings.
