PSPICE-FOR-TI: ERROR(ORPSIM-15142): Node N06179 is floating

I've Already solved this by adding a resistor.. 

but it interferes with the output, the expected result must be 12V but as you can see my result near to zero 

Please Help ! 

Hi Ihzany,

Please share your project.

Thanks,
JC

I cannot share my project here, because it's confidential sir.. 

is there any way that i can solve this issue without over sharing my project?

thanks. we'll take a look.

Thanks sir, Can't wait to hear a good news !

Hi Lhzany,

Unfortunately there's a file missing as well:

Do you have a coworker who can help you archiving the project properly so we can simulate it?

-JC

you can just delete the S-19244 schematic from the design. doesn't matter 

unfortunately in my company i'm the only one sir

What is the source that would provide the 12V output? The independent source goes to 40V and drops back to 0. I don't see how this would work. It does not look like a simulation issue.

I don't know sir.. because in TINA-TI we can run the simulation smoothly and we don't need to put resistor to our schematic. we just need to click 'Zero Initial Values' when we want to running our transient and Boom it works..

So is there any function like this in PSpice for TI? 

because this is really not convinient for us to add a resistor, if our customer see the simulation schematic and our design schematic different they will ask why.. 

Yes:

Sorry to say this sir, 

but i've already tried it and resulting still floating 

Skip initial transient bias point won't fix floating node problems. Please share your project that demonstrates the issue.

BTW, you have 2 pages under schematic1 but they seem to be unrelated:

All pages under the same schematic are simulated together so please don't put unrelated circuits under the same schematic.

Anyway, I run the simulation but did not run into the N17262 and N17258 floating problem. 

Thanks,
JC

Hi JC, 

you can try delete the resistor on CP6 and CP61 and you will find the floating problem

Thank you 

Ihzany,

which file contains the error? You can use the menu item "open file location" to open it in Windows explorer

BTW, this is the archive I created, it simulates OK (same waveform as what you shared on 12/14:

Hi JC, 

Strangely like you said it works fine! Thank you 

but can you explain why this 6Seconds here can work fast ? strangely when i tried to run 400ms for LMR33630 it takes 6 hour !

can you help me to explain why would than happend? Thank you as always JC !

Oh btw this still not resolved the question sir, i'm sorry 

you can try delete the resistor here, and you can find the problem. Thank you

i'm sorry yesterday was my mistake 

Please share the project archive that demonstrates this problem. Please note the name of the schematic and sim profile.

Thanks!

training1-2023-02-02T08-11.zip I hope this one is right sir

You can press ctrl+f and search the nets:

They don't have DC path so you cannot caluclate the voltages. Please replace the caps with 2 50nF.

Hi JC, 

I know that you are desperate to finish this answer but you need to read again my question from the begining

I've already change the capacitor but it's still produce an error 

this only can be solve by putting a bigger resistor, that's why i'm asking you why we need to put that and what if we don't want to use that ? 

and you said last time to use "skip initial transient bias" but it still didn't work

i'm asking you "WHY", I'm very desperate too right now because this issue already passed my goals

everyone did not support TINA-TI anymore and asking us client to use PSpice for TI, so please now prove to us that PSpice for TI is more than that 

Thank you!

No. What I asked was to replace the 2 100nF cap in series with a single 50n:

BTW, where did you get help with TINA-TI?
