my problem was :
************************************
hi,

comp_rate, comp_region2 and comp_region1 are inputs of the simulink real time block.

code was :

comp_ratio=comp_rate/100;

comp_range=comp_region2-comp_region1;

t=0:(comp_range*comp_ratio/comp_range):(comp_range*comp_ratio);

and error message was "Operands must be constants."

is there any other ways to write the "t" ? or isnot possible to write smt with the inputs?
**************************************
but, after your message :

I changed my codes. I summed all the algorithms of the blocks to one embedded block. so no same inputs and outputs. all calculations were made within the block.

comp_ratio=comp_rate/100;

comp_range=comp_region2-comp_region1;

t=0:(comp_range*comp_ratio/comp_range):(comp_range*comp_ratio);

And I defined the problematic data (comp_ratio, comp_region2, comp_region1) as parameter with non-tunable check from ports and data manager :

but now, the error message was

Embedded MATLAB Runtime Error: Error evaluating Embedded MATLAB parameter data 'comp_rate' (#157) in its parent workspace.

what could be the wrong with my way ?

thanks
