| DC analysis
calculates the operating point and the transfer
characteristic of nonlinear analog circuits.
Through optimization, TINA Pro will optimize a
circuit response to a predefined target value by
automatically varying the value of a circuit
parameter. In AC analysis, complex voltage,
current, impedance and power can be calculated,
and Bodediagrams, Nyquist diagrams, and group
delay characteristics can be plotted. In
transient analysis, the transient response of
analog and mixed analog/digital circuits can be
plotted. In all analysis modes, parameter values
can be both stepped and swept, and ambient
temperature can be varied. 
AC Analysis with parameter
stepping
TINA's analysis capabilities don't end with
analog circuits, but also include a powerful
simulator for digital circuits. TINA Pro solves
the logic state equation at each node and
displays the results.Trace the operation of the
circuit step-by-step forward and backward,or use
TINA's auto-running mode. The event-driven
digital engine also keeps track of internal
states, allowing the study of digital hazards. In
addition TINA Pro presents the complete time
diagram of a digital circuit. Digital signals are
displayed in a special logic analyzer style
window where each signal is dispayed in a
separate coordinate system.
Digital Timing Diagram
Another powerful feature of TINA Pro is its
capacity to analyze circuits consisting of both
analog and digital components. In mixed-mode
analog/digital simulation real voltages and
currents will be determined for all nodes as a
continuous function of time instead of as
abruptly changing logic levels. Use mixed-mode
simulation for digital circuits with key analog
portions or for analog circuits with additional
digital components. Even with purely digital
circuits, TINA's mixed mode analysis helps solve
complicated timing problems that might not be
understood using the digital analyzer.
