Analysis this schematic

[Davor]

Yes, that's the one Watching my clothes going out of fashion is more exciting than these finishing a millisecond of simulation.

Thanks for the tips. One day I might make some substitute model for these. The sw model is very quick to converge the transitions and offers enough flexibility. I like to substitute various analogue switching devices with these as they are easily convinced to assume such functions, and in most cases you are not going to benefit from too slow but accurate models anyway.

Mohandes, all,

Here are the CD4000 series symbols and a model library composed by Helmut Senewald that you might find on the LTspice Yahoo tech group. The files are untouched except that I downloaded them and combined them into the zip file.

The model library is a text file. For my own use, I have changed my copy's extension from .lib to lib.txt. I would sometimes have Altium on my machine, which registers the .lib extension for its own parts libraries (in Windows). I would want to read the CD4000.lib file and I got tired of clicking the CD4000 file, thus invoking Altium. I would wait... and wait, for Altium to open just so I could close it. You may drag-drop the CD4000.lib file into notepad if you want to read it without invoking Altium (or Protel), should either be present.

I included Helmut's instructions in the zip.

There is a newer library version on the tech group's website but I have not used it and I don't know how it works but it might be easier to use than this version.

Look at post #150 in this thread to see how to set the attributes, right clicking the symbol after it has been placed on the schematic.

These CD4000 components for the most part work really well, but as Davor pointed out the CD4538 (which is actually represented by a CD14538 model) does run really slow.Also, hystereses is not implemented which affects the CD4093 model. (Any Surfmaster PI lovers, take note).

I attempted to implement the hystereses feature by hacking the model file but quickly found out that I wasn't smart enough to pull that off.

I find many schematic circuits using the CD4538 to be practically inscrutable, so what I did for myself is to convert a CD14538 symbol into both CD4538a and CD4538b symbols, and annotate pin numbers for both halfs. That has made it easier for me to double-check a simulation I am composing against the original schematic (although mistake still occur).

Ain't no zip? Geez, I guess I screwed up.

Here I try again.

thanks
but i should work that more.merci

Hi
mr georgi and porkluvr.finally i solve it in my second board
look at the picture.
first picture for Sc and sb
second for otu pu ,x,y,z(x is yellow and z,y are blue)
finall picture are sequence piture of:x,y,z(when connect third board)
and i think alexis schematic for third part is wrong too,look the georgi schematic!
OK AGAIN I check the both schematics and if you help me thanks.please

[mohandes]

ok
i see first error,in alexis shematic dont connect all tl062 to -7and+8 volts ?
what do you think?

[georgi.g.zhelev]

ok
i see first error,in alexis shematic dont connect all tl062 to -7and+8 volts ?
what do you think?

How it will work without power ? Connect all tl062 to -7and+8 volts ! first picture for Sc and sb , OK!

[mohandes]

Hi all
i check the alexis schematic by georgi and found more errors(2 errors) but need your Experience to i am sure.i explain in the picture ,please check and say me.
thanks

[porkluvr]

Some of those signals look so alike that I am thinking that you have solder bridge somewhere. If that only occurs when the third board is connected... likely that short is on third board.

[mohandes]

hi my friend
yes ,if you look number 155 and see second picture ,these are for out put X,Y,Z before i connect to third board.can you Simulation x , y,z if you want?
and for my second pcb iam sure not connection with solder.
please see #158 and say to me your idea about them.i think the problem of hear
thanks.

hi georgi
what is your mean about : How it will work without power ?(my english is bad)

NO body know about #158
thanks

Shematics are correct !Еrrors are with you ,ОК?Check everything again.

[georgi.g.zhelev]

mohandes , now is ready to only about 15 % of Puls Star -G, OK. How will you get to the end?

Who can tell anything from looking at a single pulse?
Don't you have a dual trace scope?

On the CD4053, dual trace the following pairs

pins 11, 14

pins 10, 15

pins 9, 4

ch1 probe goes to 11, 10, 9
ch2 probe goes to 14, 15, 4

Show more than a one cycle (pps) on the screen. How about two!

Make sure you have +8 on U4-16 and -7V on U4-8 and no solder bridges between pins or between traces.

Hi
ok i measure by 2 channel forins 11, 14,pins 10, 15,pins 9, 4
i check U4(ne5534 and correct for pin 7=8volt and pin4=-7volt)
check third pcb all correct.
but i can not found U16????

dont need i measure by scope some output of third pcb,if need where?
thanks
