Introduction

The Interpreter is a powerful tool which extends TINA’s usefulness. It allows the evaluation of mathematical expressions, the solution of equations and systems of equations, the calculation of derivatives and integrals, the plotting of results, and much more.

You may liken the Interpreter to using paper and pencil for solving problems, except that you can have TINA check the results. If you use the Interpreter after DC, AC or Transient analysis, it is extremely handy for post processing the results.

Another interesting application of the Interpreter is the arbitrary definition of signals to be used as excitation for a circuit. These signals can be assigned to analog generators.

For educational users, TINA has two special modes. In examination mode, the student has to solve a series of problems (a problem set) either by traditional pencil-and-paper methods or by using the Interpreter and analysis functions. When the student finds the answer, the program sends it immediately to the teacher's machine, where it is promptly displayed by the TSuper supervision utility. In training mode, operation is similar, except that TINA gives the student feedback about the correctness of his answer, and the student may turn to the Advisor to get help prepared by the teacher.

The Interpreter can be activated from the Tools menu. Its interface is similar to that of TINA’s text editor: you enter expressions as text and then execute it as a program or an expression to evaluate or plot.
