Hello Clément,
Yes, I have some function blocks and expression blocks.
Must I understand that I have to write CBLOCK for scilab function or scilab
expression or both ?
Here are other results for a more complex project name PELT1
Time request : 100 s
Results :
Xcos Scilab 5.5.2 :
Durée de la simulation : 258.3 s
Xcos Sciab 6.1.0 :
Durée de la simulation : 4353.4 s
So the ratio is 16.8 for PELT1
Other information :
Scilab 5.5.2 : time between click go and first scope on the screen = 5 s
Scilab 6.1.0 : time between click go and first scope on the screen = 95 s
Ratio=19
and I also have other projects more complex
Pelt1 is for 1 needle (2 positonning loop)
Perlt6 for 6 !!! (7 positonning loop)

Hello Pierre,
Are you using a block with its simulation function implemented in Scilab?
Any C/C++ implemented block might perform the same at simulation time.
In 6.0.2, implementing Xcos blocks using the Scilab language had some
performance issues. In 6.1.0, I tried to speed up things a little bit by
reusing some allocated data structure during simulation time [1] ; more work
might still be needed here.

Hello,
Here I test a PELTON basic algorithm under xcos, and record with tic-toc the
simulation real time.
These programs have been set for 120 s (scope)
Results :
Xcos Scilab 5.5.2 :
Durée de la simulation : 45.4 s
Xcos Sciab 6.1.0 :
Durée de la simulation : 65.2 s
So the ratio is 1.44 for a basic sheme
Any explaination ?
Can that be improved ?
BR
