Schematic Editor

 

Circuit diagrams are entered using an easy to use schematic editor of TINA. Component symbols chosen from the Component bar are positioned, moved, rotated and/or mirrored on the screen by the mouse. TINA’s semiconductor catalog allows the user to select components from a user-extendible library. An advanced “rubber wire” tool is provided allowing easy modification of the schematic diagrams. You can open any number of circuit files or subcircuits, cut, copy and paste circuit segments from one circuit into another, and, of course analyze any of the currently open circuits.

TINA gives you tools to enhance your schematic design by adding graphics elements such as lines, arcs, arrows, frames around text and title blocks. You can also draw non-orthogonal (diagonal) components such as bridges and 3-phase networks.

You can also copy and paste analysis results (diagrams) into the schematic diagram and vice versa, and so store the schematic design together with the circuit analysis results.

Electrical Rules Check (ERC) will examine the circuit for questionable connections between components and display the results in the Electrical Rules Check window. ERC is invoked automatically, so missing connections will be brought to your attention before analysis begins.

Text and Equation Editor. TINA includes a Text and Equation Editor for annotating schematics, calculations, includes graphic output, and measurement results. It is an invaluable aid to engineers documenting designs and teachers preparing problems and examples.

In addition to schematic diagrams all of TINA's analysis functions will work from PSpice format netlist input as well. Netlists appear in a netlist editor window as text which can be edited and saved. Netlists can be exported and imported in Pspice format and also to drive popular PCB packages such as ORCAD, TANGO, PCAD, PROTEL, REDAC and other programs.

The circuit diagrams and the calculated or measured results can be printed or saved to files in standard Windows BMP, JPG and WMF format. These output files can be processed by a number of well-known software packages (Microsoft Word, Corel Draw etc.).

In summary, the Schematic Capture tool of TINA provides a powerful yet convenient way to create or edit your circuits.
