Hi,

The wreal approach is a nice way to handle real signals, which then can be used to describe analog-like quantities, in a pure event driven simulation (digital simulator). This real signal could represent eitherway a voltage, or a current, but there is no physical meaning here, no electrical discipline... It is just a real signal, which the designer uses to represent something...
The Verilog-A(MS) has been developped to cover this analog physical representation, defining disciplines to formulate the voltage/current duality.
So, I would say take benefit of the VerilogAMS to achieve what u want here.
U can connect wreal to electrical, and get good results if u set properly the ConnectModules in between.

Cheers,
Jerome

wreal is one value one way all the time, at least as currently defined by the most recent version of the AMS LRM.  
Even if you are using electrical discipline, if its a Voltage driven from outside, you cannot sense, the current, you have to DRIVE the current, as appropriate to the voltage coming in. the node driving the voltage will sense the TOTAL current coming from all loads.
In the electrical world you can drive either voltage or current, but not both. and you can sense either, but you have to drive the other.
or your network is indeterminate.
