Model Composer also supports a half
precision floating point data type, which is 16 bits wide instead of 32 bits, because it
consumes less real estate on the target device when implemented on the FPGA. This is an
important consideration when designing in Model Composer. However, Simulink does not support the half
data type,
and this can lead to errors in simulation. The solution is to use the Model Composer DTC block
to convert the half
into the single
data type supported by Simulink, for
those portions of the design that are not in the Model Composer sub-module and will not be
part of the generated output.
