LTSpice www.analog.com

•   LTspice® is a complete Spice oriented software.
•   It is supported by Analog Devices.
•   It has millions of users.
•   Schematics and waveforms display contain numerous tools.
•   DC, DC sweep, DC transfer, Noise, AC and transient analysis.
•   Compliant to most Spice librairies.

LTSpice is a fast, robust, and efficient 1D calculation software with schematic input. It is a much improved version of Spice, and also a mixed simulator. It is available for free. It is now multi-task. It underwent some changes recently in algorithms and interface improving speed, but less robust. Anyway Analog Devices is upgrading continuously.

Tcl/Tk www.tcl-lang.org

•   Tcl/Tk is easy to learn and maintain.
•   It is a reliable software endorsed by EDA industry.
•   Its community is active and friendly.
•   Its documentation is complete and detailed.
•   It is the only script language with an integrated graphical library.
•   It has been ported on many operating systems

Tcl/Tk is one of the first scripting languages, along with Perl and Python. It is slower than programming languages such as C or C++, but it is robust, and its graphics library allows it to do everything. It is used for application aggregation. It is possible to compile and create the binaries according to your own needs because it is an open source project.
