The other approach was to manually exchange the function call in the generated

code. The function call is made in one place only in the whole code. The block

Quantisation, Figure 9, has two inputs which are the function parameters, but

Real-Time Workshop Embedded Coder always optimises away the declaration of

any irrelevant signal. This made it hard to have access to both inputs since one of

the signals is terminated inside the block and thus optimised away in the

generated code, see Figure 9. The solution to this specific problem was to make a

small change inside the Quantisation block in order to have access to both inputs

in the code, see Figure 10. This solution did not affect the rest of the generated

code since the whole subsystem was chosen to be a function with its own code

file. As mentioned earlier this problem could have been solved using Legacy

Code Tool.
