You can edit the Hidden Pins property of the ULN2003,and let GND(Pin8) connect to another net(e.g. 547_C),then you should add 547_C to power rail list(Design--Power rail).Now put net lable 547_C on the BC547's collector.
Try it,you'll find Pin8 of ULN2003 only connect to collector of theBC547.

If you invoke undo command,ARES seems crashed!

The original size is too small,but I can't find a way to change it,please help.
Thanks

Thanks a lot!

When I short D1,D2 of the sample design "Poweramp.dsn",I can't see any cross-over distortion! I've change Q1,Q2 to some SPICE models,the result is the same.
We need to explain it to some customers. Pls help us.

System-Set Template-Check to "Show" part value.

It's important to global modify something,e.g. to change the particular component's pad size.

Maybe the picture can't show the issue clearly,let me attach the whole design.
Please note,in this design the output of AD623 is higher than 32V even when I short it's input to ground!

First,I was confused by the attached DSN file which was using an AD623 and a LM358 to build a simple voltage amplifier,the problem is: 1, AD623's output is -12.0757V when simulating!? 2,If I change LM358(SPICE Model) to LM358N(Schematic model).there is no problem; 3,Even if I replace LM358 with SPIC...

Thanks again for your help!

Thanks a lot!
Would you like to give me an example of using Laplace Primitives? I need to introduce them to our customers.

The active relay model works well during simulation,but the relay's appearence can't go back to state 0 when simulation is stopped.
What's wrong with it?

Thanks a lot! Please tell me the book in detail.
I hope to know the desciption of all properties used by Proteus,just like
GANG,STRAT,etc.

There is a "LISA Model file" in some component's properties ,what's the meaning of LISA?
Where can I find the description of all kind of properties, are there a table of all properties?

HELLO everyone: Recently i am obsession about ASEM51,I write some source code ,and i compiled it in keil uv2 with no error,the output format is .hex. and i want some debugging informaiton,so add a new source using tool of ASEM51,but when i compile it ,it always appear some errors. why,the same codes...
