How can in I find loop filter block in CCSDS TM HDL receiver in R2023b simulink?

Iam trying to practice the CCSDS TM HDL Receiver in R2023b version in simulink but unable to find blocks like Loop Filter ,interpolation control and my question is ,when this type of situation occurs how to find the blocks which are not available in packages ?

I assume that you are referring to this example. For HDL implementation, these are implemented as Simulink subsystems using Simulink blocks and MATLAB functions. If you open the example, you should be able to look at the subsystem to see how it is implemented.

[Pavan]

yes,I did that.But unable to find the subsystems in simulink library browser .In these cases ,is there any other ways to find the blocks ?

[Bharath Venkataraman]

This is a subsystem in the example, so you cannot find it in the Simulink library browser. You will need to open the example to get to the subsystem.

Thank you sir for the response.I understand how to see the example and look for the blocks .

Hi Pavan,

I understand that you want to know how you can find the blocks which are not available in packages.

When you encounter a situation where you are unable to find specific blocks in Simulink, there are a few steps you can take to address the issue:

1. Check the Simulink Library Browser and use the find bar or search into the category of your desired block.
2. Search the Documentation
3. Simulink has a wide range of add-on products and toolboxes that extend its capabilities. These add-ons might contain the blocks you are looking for. Check if there are any relevant add-ons or toolboxes available for your specific application.
4. Consider making custom blocks using MATLAB's S-function or MATLAB Function blocks.

Thank you sir for your response. So, is the loop filter used in the documentation was custom made using MATLAB function Block? Or is it available in the simulink library browser?
