The SrcWorkspace Name-Value pair argument to the sim() command seems to have disappeared going from 2020b to 2021a. I searched the 2021a Release Notes and could find no mention of its removal. Did I miss that in the ReleaseNotes? More importantly, how does one implement that functionality now?

Looks like one has to use a Simulink.SimulationInput object as the input to the sim() command.

True.

In fact, 'SrcWorkspace' is also buggy and does not work well with data dictionaries (see e.g. https://www.mathworks.com/matlabcentral/answers/367223-using-srcworkspace-with-data-dictionaries), so Simulink.SimulationInput seems to be the way to go.

Another reason to avoid 'SrcWorkspace' might be that it seems to have issues also when using with the parallel computing command 'parfor' (see e.g. https://www.mathworks.com/matlabcentral/answers/94215-how-can-i-set-the-source-workspace-to-caller-when-using-a-the-sim-command-from-a-function-in-simul).
