CristalCaveGem » LustreC

(* An application that loads json provided input and produces Lustre

Usage:

lustrei -vhdl myvhdl.json 

lustrei -scade myscademodel.json 

  will produce a lustre file that can be compiled and analyzed

VHDL is handled in a double way: as a backend and as an import language

In a first step, lustrei -vhdl -print myvhdl.json shall print the VHDL model in stdout
