i have this erorr in pspice
ERROR -- Less than 2 connections at node N00973

 

Where are the power pins for the chip? The Enable pin needs access to Vdd and Vss.

 

What is with the colored dot at the top of R1? Does it possibly indicate that the wire does not connect?

I assumed the green dot links the error message to the location on the schematic.

 

hi,
From the pin numbers 1,2,13 it appears he is using a Gate section from a 14 pin IC, similar to the 4066 analogue gate

He has not declared VCC or the 0V connection.

Please post your LTS asc file, we can then check the simulation.

Welcome to AAC!

i have this erorr in pspice
ERROR -- Less than 2 connections at node N00973

Which node is N00973? What are the supply voltages?

Your schematic would be easier to read if you didn't have so much white space, cropped the relevant portion, and didn't run wires over text.

 

ok i send with this massage my design file
i enable the power pins and 2 number at the ic has been shwon but still dont know what to do
the picture is this
but still have an erorr at the pspice
the nodes adress and the erorr is this
**** INCLUDING adfsfad-SCHEMATIC1.net ****
* source ADFSFAD
V_V1 N00277 0 5Vdc
V_V2 N00313 0 5Vdc

hi m550,
Your model has problems.
Download and unzip this file into its own folder, it has the CD4066 analogue gate information for LTspice.

Ask if you have a problem.

my simulation is in pspice do you know how another ic i can use in pspice to do the same work i dont want to use LTspice.

 

hi m550,
I do not use Spice, but I have found this link for the 4066
Do you know how to create a Spice model from a file.?
If not, check online for guidance.

The thread title and schematic in the first post says 4016, not the newer and more powerful 4066.

 

actully i dont know how to use lib file i can use olb file please help me and thank you for all of your good answers

 

Most ICs have a wide range of specs listed in their datasheets. Some have good specs and others with the same part number have poor and different specs.
A simulation program usually shows only devices the "typical" specs then if you build a circuit that works fine in a simulation it might not work or work poorly with purchased devices that have different specs.

Your very low 5V supply voltage and a very low 1k load resistor shows on a graph in the datasheet working very poorly with a device that has "typical" specs. When turned on a device with typical specs cuts the signal to half the level of the 5V input.
With a 10k or 100k load the graph shows it working better but still poorly with a 5V supply.

Another graph shows a 10V supply and the CD4016 working poorly with a 1k load and working fairly well with a 10k or 100k load.

Since a simulation program does not read datasheets then you must calculate how devices that you purchase with different than "typical" specs will perform.

A newer and more powerful CD4066 works better than a CD4016. Compare their datasheets.
