Fixed-Point Blockset

Block Icon Labels

Many blockset icons look like those of built-in Simulink blocks. For this reason, all fixed-point icons have an "F" (for "Fixed-Point") associated with them. An "F" in the lower right (upper left) corner of the icon means the block output (input) is a Fixed-Point Blockset data type.

The FixPt Gateway In, FixPt Gateway In Inherited, and FixPt Gateway Out blocks have additional labels, which reflect how the input and output signals are treated. If the block input or output is treated as a real-world value, then a "V" appears by the relevant port. If the block input or output is treated as a stored integer, then an "I" appears by the relevant port.

Many blocks have additional labels that indicate logical operations, arithmetic operations, numerical values, and so on. These labels will help you to quickly understand the behavior of fixed-point models without examining individual block dialog boxes.
