|
|
You can use subcircuits to implement custom "black box" devices.
|
||
|
|
<p>
|
||
|
|
Create and test your device, and then use labeled nodes (under "Outputs and Labels") to mark and label all the inputs/outputs. <a href="circuitjs.html?cct=$+1+0.000005+10.20027730826997+53+5+50%0Aw+304+64+304+128+0%0Ad+304+128+368+192+2+default%0Ad+304+256+368+192+2+default%0Ad+240+192+304+128+2+default%0Ad+240+192+304+256+2+default%0Aw+304+256+304+352+0%0Aw+368+192+416+192+0%0A207+304+64+304+16+4++in%5Cp%0A207+304+352+304+400+4++in-%0A207+416+192+480+192+4++out%5Cp%0A207+240+192+160+192+4++out-%0A">Here is an example circuit (a bridge rectifier).</a>
|

|
|
<p>
|
||
|
|
Then, select File->Create Subcircuit, then rearrange the pins the way you want them, enter a model name, and click OK. This will load the subcircuit model.
|
||
|
|
Be sure to save this circuit (the subcircuit implementation), because it can't be edited later otherwise.
|
||
|
|
<p>
|

|

Now you can create a circuit using the subcircuit model. <a href="circuitjs.html?cct=$+1+0.000005+10.20027730826997+59+5+50%0A.+fullrect+0+2+2+4+in%5Cp+1+0+2+in-+3+1+2+out%5Cp+2+0+3+out-+4+1+3+DiodeElm%5Cs1%5Cs2%5CrDiodeElm%5Cs3%5Cs2%5CrDiodeElm%5Cs4%5Cs1%5CrDiodeElm%5Cs4%5Cs3+2%5C%5Csdefault%5Cs2%5C%5Csdefault%5Cs2%5C%5Csdefault%5Cs2%5C%5Csdefault%0A410+688+288+784+368+1+fullrect+2%5Csdefault+2%5Csdefault+2%5Csdefault+2%5Csdefault%0Aw+688+288+688+240+0%0Aw+688+320+688+368+0%0Aw+688+368+640+368+0%0Aw+688+240+640+240+0%0Av+640+368+640+240+0+1+40+5+0+0+0.5%0Aw+784+288+784+240+0%0Aw+784+320+784+368+0%0Aw+784+368+832+368+0%0Ar+832+240+832+368+0+1000%0Aw+784+240+832+240+0%0Ao+9+64+0+4099+5+0.025+0+2+9+3%0A">Here is an example using the rectifier.</a> When you save/load this circuit, it will also save/load the subcircuit model so you can use it in other circuits.

You can also use subcircuits to rearrange pins on the built-in chips. <a href="circuitjs.html?cct=$+1+0.000005+10.20027730826997+50+5+50%0A165+800+368+848+368+6+0%0A207+864+336+864+288+0+Vin%0A207+800+400+752+400+0+dis%0A207+800+464+736+464+0+tr%0A207+800+496+736+496+0+th%0A207+864+528+864+592+0+ctl%0A207+896+528+896+592+0+gnd%0A207+928+432+992+432+0+out%0A207+928+400+992+400+0+rst%0A">Here is an example with the 555</a>.

<p>
|
||
|
|
If you select part of a circuit before using File->Create Subcircuit, then only the selected elements will be considered part of
|
||
|
|
the subcircuit.
|
||
|
|
<p>
|
||
|
|
If you want to use labeled nodes in the subcircuit definition but don't want them to be one of the inputs/outputs, then check the "Internal Node"
|
||
|
|
checkbox in those labeled nodes' edit menus.
