Can I visualize or display signal data on the screen connected to my Speedgoat target computer?

There is no more "Target Scope" block shipped with Simulink Real-Time R2020b or later releases. It used to be available in 'Graphical' and 'Numerical' modes.

How can I visualize or display the signal data on a screen connected to my Speedgoat target computer in newer releases?

Simulink Real-Time went through a major product update for the R2020b release. Graphics support has been removed as part of this in favor of a more performant SSH shell-based BlackBerry® QNX Neutrino® real-time operating system. This means that it is no longer possible to visualize signals on the target screen. Instead, a text-based status monitor is visible on the target screen:

You can use the methods outlined in the following MATLAB Answer to visualize live data from your real-time application on a connected host computer:

How can I live-stream and visualize signals from my Speedgoat target computer running a real-time application? 

The simplest approach is to mark your signals for logging, which enables live streaming to the Simulation Data Inspector (SDI) in MATLAB. See:

How to stream real-time signal data from Speedgoat hardware to Simulation Data Inspector (SDI) for live monitoring in R2020b and beyond?

If your Speedgoat is running in standalone mode and connecting a host computer is not an option, you can consider printing messages to the system log within the status monitor, as demonstrated in the following documentation example:

Hi Allen & Christopher, the SDI performance has improved tremendously with our latest R2021b release, so I can only encourage you to always stay up to date with our latest MATLAB release.

PS. as for decimating the data streamed to SDI, you can use the "Logging Sample Time" option that is discussed here: https://de.mathworks.com/matlabcentral/answers/882723-how-can-i-improve-the-signal-streaming-performance-of-simulation-data-inspector-sdi-when-using-sim
