please help me to know what is this schematics problam


there is an [ Less than 2 connections at node N00630] errore

Re: please help me to know what is this schematics problam

the schematic does not give where is node n00600.
attach the nodes fig for the solution.

it may be the connection between pin2 of U1 and pin1 of U2.

[this is the net list]

Re: please help me to know what is this schematics problam

That's the netlist of a different circuit. No N00630 present, no single connection nodes at first sight.

Hi,

I can't help you with the problem,
But I'd like to comment your schematic.

The drawing is very confusing.
It is very hard to understand, because the signal flow is not intuitive.
Many unnecessary crossings, unnecessary bends, unnecessary long wires.
The GND wiring is horrible. Signal flow from right to left and back...

Usually one tries a signal flow from right to left.
Higher (supply) voltages at the top, or symbols pointing to top.
Lower voltages at bottom..
Use more GND symbols, less GND wires...

A clean schematic helps others to understand the schematic more easily. (Like here in the forum)
And it will help yourself to understand the schematic ... especially after some months or years.

Please don't get me wrong. I know my schematics looked similar than yours .... a long time ago.

Klaus

Re: please help me to know what is this schematics problam

Still a different circuit. R2, R20 and R200 are e.g. missing, Q11 base is respectively floating, which causes the error.

You didn't yet show the net list belonging to the schematic in post #1.

Hint: There should be a net list entry for each component, just count it.

Re: please help me to know what is this schematics problam

thank you for your advise i try to improve it and share it again

actuly i want simulate this circuit but each time i try i cant secsus

Re: please help me to know what is this schematics problam

For a clarity, you should restrict to the circuit part of interest, e.g. the center part. In this case you apparently didn't manage to connect two resistors representing the potentiometer RV1.
