C Code Generation (simulation) Released

Thanks to a generous contribution back to the OpenDF repository of their Cal2C compiler, the folks at IETR/INSA of Rennes -- -- have enabled the direct compilation of OpenDF dataflow applications to C source code for simulation. Written in Ocaml, Cal2C generates C source code that layers on top of SystemC. Application execution of the compiled C is an order of magnitude faster than the existing (interpreted) simulation core. ... read more

Updated Eclipse UI

New versions of the Eclipse plug-ins for the CAL/NL editor and simulation run config have been posted to the Opendf eclipse update site at:

The editor plugin (version 1.2.4) contains syntax hihglighting, source outlining, and improved error location reporting.

The simulation run config plugin (version 1.1.0) now supports full configuration of the simulator, including specification of model search path, top model parameter values, processing options, verbosity, etc.
