Hi guys.. 
I've one observation. 

This is my high level code.
```
export const power_circuit = () => {
  return (
    <board name="main-power-circuit" routingDisabled={true}>
        <BmsMonitorModule name="monitor_module" schX={0}/>
        <CurrentSensing name="current_sensing" schX={5}/>
        
        <HighVoltagePowerSupply name="hv_supply" schY={5}/>
        <CommunicationBridge name="com_bridge" schX={5} schY={5}/>
        
        <trace name="tr_cvdd" from="monitor_module.CVDD" to="hv_supply.LV_OUT"/>

        </board>
  );
};
```
If the modules are defined inside <subcircuit>, then the <trace> will not connect. If modules are defined inside <group>, <trace> is connects the ports without any issues. Attached images show both conditions


**Case 1: module as <group>**
```
export const BmsMonitorModule = ({ name, schX, schY }: BmsMonitorModuleProps) => {
  return (
    <group name={name} schX={schX} schY={schY} showAsSchematicBox>
      ...
    </group>
)
}
```
**Case 2: module as <subcircuit>**
```
export const BmsMonitorModule = ({ name, schX, schY }: BmsMonitorModuleProps) => {
  return (
    <subcircuit name={name} schX={schX} schY={schY} showAsSchematicBox>
      ...
    </subcircuit>
)
}
```

hey yes, use exposedNets

## Seve — 2026-07-13T16:44:34.005000+00:00

that will expose nets outside the subcircuit

subcircuits are isolated by default- this is actually useful in a lot of contexts but can be confusing
