xBlock Error Messages
Condition
Error Message(s)
When calling
xBlock(NoSubSourceBlock, …) and the
source block does not exist
Source block NoSubSourceBlock cannot be found.
When calling xBlock(sourceblock,
parameterBinding), and the parameters
are illegal, xBlock will report the Illegal
parameterization error. For example,
xBlock(‘AddSub’,
struct(‘latency’, -1));
Illegal parameterization: Latency
Latency is set to a value of -1, but the value must
be greater than or equal to 0
When the input port binding list contains
objects other than xSignal or xInport:
Only objects of xInport or xSignal can appear in
inport binding list.
When the output port binding list contains
objects other than xSignal or xOutport:
Only objects of xOutport or xSignal can appear in
outport binding list.
If the first argument of xBlock is a function
pointer, the 2nd argument of xBlock is
expected to be a cell array, otherwise, an error
is thrown:
Cell array is expected for the second argument of
the xBlock call
If the source configuration struct has toplevel
defined, it must point to a Simulink
Subsystem and it must be a char array,
otherwise, an error is thrown:
Top level must be a char array
If an object in the outport binding list has
already been driven by something, for
example, if you try to have two driving
sources, an error is thrown. (Note: the error
message is not intuitive, we will fix it later.)
Source of xSignal object already exists
xInport Error Messages
Condition
Error Message(s)
If you try to create an xInport object with
the same name the second time, an error is
thrown. For example, if you call p =
xInport(‘a’, ‘a’).
A new block named 'untitled/Subsystem/a' cannot
be added.
