Rule
Sub ID a
When using fixed-point values as the input to the multiplication and division Product block, the sign of the data type shall be the same for all input signals.
Custom Parameter
Not Applicable
Rationale
Sub ID a:
A utility function is created for each least significant bit (LSB) when fixed-point code is generated. Unification of data type signs can reduce the number of utility functions.
Verification
Model Advisor check: Check signs of input signals in product blocks (Simulink Check)
