# MATLAB: Can I put assertions in the Parameters section of the .SSC file

Simscape

I have been using the setup section in Simscape to handle error checking for parameters/inputs upon initialization, but now it appears as though the setup section is no longer recommended. MathWorks suggests using assertions to handle errors (which I already use for dynamic variables/inputs), but it seems like extra/wasted computation cost to run assertions over and over for static parameters/inputs. Is it possible to use assertions in the parameters section of my .SSC file, or could this be added in a future release?
