How to link between workspaces

[Myrto]

Hello! As I'm new to Matlab Simulink I am not sure how to connect blocks between files.
For example, I have a.mdl and b.mdl. How can I create a connection between the two of them so that when a 1-D value of a.mdl changes, the b.mdl changes its results according to the new value automatically?
Is there such a feature? And if so how do I do that?

try sending the variables in model "a" to the base workspace, and keep monitoring those variables in "b" model... to keep the workspace clear, u can make them global.
