• Significance length:
  • Currently the significance length inside the SCADE model is set to 200 characters at a maximum
  • Thus the compiler choosen has to support at lease a significance length of 200 characters [1]
  • Thus the linker choosen has to support at lease a significance length of 200 characters [1]
