• How does interact TkFab with other software (input) ?

After simulation has run, the serious softwares gave the possibility to export results in plain text, it can be :

•   Columns of values, with one column per value
•   Specific arrangements for complex results, such as fields for FEA software.
•   Standard formats such as CSV, TSV, VCD, VTK, HDF …

Data can also be organized with a spreadsheet software and in that case, the export format is in accordance with the CSV format :

•   Columns of values, with one column per value acording to Comma Separated Values

TkFab takes these different formulations to convert them in a richer CSV format. It is still conform to the CSV format but with a few extra lines :

•   Parameters and their unit (for multi-simulations).
•   Line with the name of the signal or variable.
•   Line with the unit of the signal or variable.

Note : It is far better to interact with the executable of the software to use internal commands ( QuickField™ ) or use the command line feature ( LTspice® )

Some columns are added for the user and an index. Conversion is not straightforward since, for instance, in some countries the point for the representation of doubles is a comma. Another example is the representation of complex numbers that has many possibilities.

This representation can then be changed into a matrix (for sorting), a table (for interpolation), a dictionary (as internal database). It allows different measurements and computations.

• How does interact TkFab with other software (output) ?

It can edit the definition of a design and change parameters or data :

•   Edit, change the definition of problem or netlist.
•   Creation of a piecewise-linear function.
•   Create the curve defining the behaviour of a material.
•   Drive a cycle of simulations.
•   Make engineering calculations to estimate some values.
•   • • • 

Depending of the advanced functions of the external software, it can allow simulation with new parameters (parametric simulations), define limits for acceptation (design specifications), define a strategy to limit the number of simulations (design of experiments).

• How does interact TkFab with your design ?

It completes your design with sub-projects where the results are stored in a database. Results and measurements are quick to find for a design review.

Before storing the converted results coming from the external software, it can :

•   Makes its own measurements and calculations.
•   Performs analysis on the performance of your design.
