I believe this is not supported currently. The immediate issue here could be resolved by removing the --specialize-nx so that the Nexus primitives are not directly instantiated.

But the larger issue is modeling the extra memory ports to the Activation Arena -- this is modeled in the 100% Verilator simulation, but not in the Renode simulation.

Nope. Not sure what happened.
