Hi Thasvinthiran,
For blocks such as Inport, Mux, Demux, and Add, it is necessary to provide the signal dimensions. Without them, you can face issues with model simulation. As the error message indicates, by introducing the Signal Specification block, one can explicitly define the dimensions of the model. The following steps can be followed to use the Signal Specification block:
- Add a Signal Specification Block using the model browser.
- Double-click on the Signal Specification block; a dialog box will open.
- Set the Dimensions parameter to the desired value (e.g., [1] for a scalar, [n] for a vector of length n).
- Connect the block just before the signal path where this error occurs.
For more information on the Signal Specification block, you can refer to the following link
Also, this error can occur due to presence of Algebraic Loops in the system. So you can also try to check and resolve any algebraic loops present in the model by referring to the following link:
I hope this information helps you!
