TINA provides an extremely powerful multicore analog circuit simulation Spice engine with excellent convergence, highly efficient and accurate simulation.  In addition to Spice components analog circuit simulation in TINA may also include Verilog A and Verilog AMS components. Of course digital components, including VHDL and Verilog components as well, can also be added to circuits. These circuits are discussed under Mixed Circuit Simulation

DC Analysis

DC analysis calculates the DC operating point and the transfer characteristic of analog circuits. You can display the calculated nodal voltages or component currents in a table or at any node by selecting the node with the cursor. Powerful methods (source- and Gmin stepping, adaptive voltage and step-size limiting) are implemented to find the operating point even for strongly nonlinear cases with hard convergence properties. You can also calculate and display in a diagram the temperature dependence of any voltages or currents in your circuit.

AC Analysis

AC analysis calculates RMS amplitude and phase of voltages and currents in your circuit and the complex power of selected parts. You can display the calculated complex nodal voltages or component currents in a table or at any node by selecting the node, part, or instrument with the cursor. In addition, Nyquist and Bode diagrams of amplitude & phase and group delay characteristics of analog circuits can be plotted. You can also get the complex Phasor diagram. For non-linear circuits, the operating point linearization is done automatically

Transient Analysis

In the transient and mixed mode of TINA, you can calculate the circuit time response to the input waveform, including pulse, unit step, sinusoid, triangle, square, general trapezoidal waveform, Spice PWL table, .WAV files and user-defined excitation) parameterized as required. You can also use components with initial conditions to accelerate circuit startup.
