Re: [Gems-users] Link Between External Nodes

[Mike Marty <mikem@xxxxxxxxxxx>]

Why do you want to avoid a PerfectSwitch?  GEMS works by connecting 
controllers to the interconnect model.
I've experimented with adding SLICC syntax to allow a controller to 
directly access state from another controller.  Some of the limited 
functionality still exists in SLICC, but I've never really used it for 
anything.
