Vivek Vijayan - Is it possible to expose ports/...

I'm looking for something like this ``` export const power_circuit = () => { return ( <board name="main-power-circuit" routingDisabled={true}> <subcircuit name="monitor-module" schX={0}> <BmsMonitorModule /> </subcircuit> <subcircuit name="communication-bridge-module" schX={0} schY={-30}> <CommunicationBridge/> </subcircuit> <pinheader name="J_IN" pinCount={2} schX={0} schY={0} /> <trace name="t_input1" path={["monitor-module.pin1", "J_IN.pin1"]} /> <trace name="t_output" path={["communication-bridge-module.pin1", "J_IN.pin2"]} /> </board> ); }; ```

https://docs.tscircuit.com/elements/group I believe you could use the <port /> component, it's documented for groups but I believe it should work for subcircuits too

let me try..

yes.. this is working for <subcircuit> as well.. thanks <@778624824875941908>

awesome, we'll be sure to document it under <subcircuit /> to avoid future confusion

you can also use `exposedNets` for subcircuits, or just write selectors that include the subcircuit e.g. `to=".MySubcircuitName .U1 .pin1"`, but shibo's suggestion is good!!!

first I thought about this `to=".subcircuit .u1 .pin1` approach. But the port based isolation feels more intuitive and clean..

i agree!

``` interface ModuleProps { name?: string } export const RCfilter = ({name}: ModuleProps) => {return ( <subcircuit name="FILTER" showAsSchematicBox connections={{ IO: "R1.pin1", VCC: "C1.pin2", }} > <port name="IO" direction="left" /> <port name="VCC" direction="right" /> <resistor name="R1" resistance="10k" footprint="0402" /> <capacitor name="C1" capacitance="10uF" footprint="0603"/> <trace name="tr_c1_r1" from="R1.pin2" to="C1.pin1" /> </subcircuit> ); }; export default () => ( <board width="10mm" height="10mm"> <RCfilter name="rc"/> <resistor name="R13" resistance="10k" footprint="0402" /> <trace name="tr_c1_r1" from="FILTER.IO" to="R13.pin1" /> </board> ) ``` What is wrong in this code? I'm getting following errors: ``` pcb_trace_missing_error:Trace [.FILTER > .IO to R1.pin1] is not connected (it has no PCB trace) @tscircuit/eval@0.0.996 • @tscircuit/core@0.0.1425 pcb_trace_missing_error:Trace [.FILTER > .VCC to C1.pin2] is not connected (it has no PCB trace) @tscircuit/eval@0.0.996 • @tscircuit/core@0.0.1425 pcb_trace_missing_error:Trace [FILTER.IO to R13.pin1] is not connected (it has no PCB trace) @tscircuit/eval@0.0.996 • @tscircuit/core@0.0.1425 ``` Also rendered PCB and schematic are wrong.

Hmn this seems like a legit bug to me at a glance

Also, I've one more doubt. https://docs.tscircuit.com/elements/group#example-led-matrix-module This section explains how to setup led matrix module. But nothing is specified about the internal circuit, how each LED is connected inside and how led ports are connected to module ports. Specifically I'm interested in the method to connect the internal component pins with the module ports.

Any suggestions or workarounds for this? I'm stuck in this..

that section is incomplete, as you can see the pcb is not connected, it's just showcasing how to expose pins on the schematic box

can you try something like this: ``` <group name="MATRIX" showAsSchematicBox> <port name="ROW1" direction="left" connectsTo={["D1.pin1", "D2.pin1", "D3.pin1"]} /> <port name="COL1" direction="right" connectsTo={["D1.pin2", "D4.pin2", "D7.pin2"]} /> <led name="D1" color="red" footprint="0603" /> {/* remaining LEDs */} </group> ```

you basically just connect the port internally

we'll get a doc on this asap

<@1050759023194030111> did this work? I did some more interal testing and it seems to work

going to document it now

<@778624824875941908> yes It worked... Thanks..

Np

<@1050759023194030111> we updated the docs for port usage, can you please give it a quick read and tell me if there's anything unclear https://docs.tscircuit.com/elements/group https://docs.tscircuit.com/elements/port

Went through both documentations https://docs.tscircuit.com/elements/port#group-interface-ports : this is exactly what I was looking for earlier. Clear and unambiguous.. Port mapping table in the LED matrix section clearly explains the internal connections. The resistor example feels self explanatory. Great documentation <@778624824875941908> I would suggest one more modification in the resistor example section of https://docs.tscircuit.com/elements/group#example-led-matrix-module. If you could provide a complete board example here, it would be much simple and easier for new users. One particular challenge I faced with <group> object was passing the name of the group from a top level module where the group is implemented. A complete board example would naturally address this concern as well.

awesome, tysm for the feedback
