TkGate is a event driven digital circuit simulator with a tcl/tk-based graphical editor. TkGate supports a wide range of primitive circuit elements as well as user-defined modules for hierarchical design.
PEP is a modelling and verification framework for parallel systems, providing a large number of different modelling languages and verification techniques (e.g. SDL, Petri nets and model checking)
MMTL, the Multilayer Multiconductor Transmission Line 2-D and 2.5-D electromagnetic modeling tool suite, generates transmission parameters and SPICE models from descriptions of electronics interconnect dimensions and materials properties.
QConsole is a custom Qt widget implementing a standard console to be inherited to support a specific scripting language or shell, and then embedded in any Qt application. As example, a Tcl console (QtclConsole) is provided for use in EDA applications
openCarac : Automatize your Spice simulator runnings
openCarac aims to automatize the characterization of electronic circuits using your favourite Spice simulator and provide output files in HTML, LaTeX (c) and GNU Octave (c) scripts. openCarac is natively compatible with various simulators including: - Ngspice (c), http://ngspice.sourceforge.net - Gnucap (c), http://gnucap.org/dokuwiki/doku.php?id=gnucap:start - Xyce (c), http://xyce.sandia.gov It comes with an API which permits to add other features and extend openCarac compatibility; openCarac is also TCL package and comes with functions that can be called in any TCL script. Adding a GUI is the next step in openCarac development, it will be available in a future release.
