LM5158-Q1: SEPIC simulation fail to run

Hello, 

Thanks for reaching out. We are currently looking into this matter and will come back to you as soon as possible.  

Kind regards,
EM

Hi Nimrod,

It does not look like you were running the simulation profile SPEIC-Sepic. Please share the .out file (click file -> Open file location and you should see it).

This is what I got (unpack snvmc90 and open in PSpice, then right-click SEPIC-Sepic and select "make active". this automatically make the schematic SEPIC the root schematic):

Thanks,
JC

Thanks, 

There is no "make active"  in OrCAD that I can see only make root that worked before I updated the this version of OrCAD

ERROR(ORPSIM-16318): Missing or invalid expression

You are simulating schematic "SEPIC", profile "sim1".

What is "sim1"? If you unzip snvmc90 as-is, there's no simulation profile called "sim1".

Please look at my screenshot, the one I simulated is schematic SEPIC, profile "Sepic".

Please send the .OUT file. What you posted is copied from the simulation window and is incomplete.

Thanks,
JC

Hello,

1. Opening the design I see on the left a list for design, I select the "Sepic" right click and select "Make root"

2. Opening the page name "Sepic" I have only one option "Make new Simulation Profile"

3. On the new popup window I select on the "Inherit From:" drop down "SEPIC-Sepic" profile

4. On the Name I can  type any name if you need. I can type "Sepic" but this will generate and error as "Sepic" exists (selected in the Inherit From drop down)

for the Out file if you point me to how to add a file I will add it but the paste if the full content of the file opened with a text editor copied and paste with no changes

Thanks

What I meant was to make the sim profile active, not the schematic:

BTW, please edit this sim profile:

Check the option "library":

Now run the simulation, then open the .OUT file folder:

Insert the file to your post:

Thanks!

Hi Nimrod,

This file does not show any error. Is it from a failed simulation?

Thanks,
JC

Hello,

Yes,

on line 111 "ERROR(ORPSIM-16318): Missing or invalid expression"

Thanks. I don't have that (right side):

Would you please zip up the entire directory and attach it here?

Thanks,
JC

Hi Nimrod,

What's your SPB version?

Thanks,
JC

Hello,

I am using OrCAD capture 17.4-2019-S032

Hi Nimrod,

Would you please go into the simulation directory, open a command window and enter this command: "c:\Cadence\SPB_17.4\tools\bin\psp_cmd.exe Sepic.cir"?

Thanks,
JC

Hi Nimrod,

And this generates the same .OUT file as you posted above?

What's your OS' language / localization?

Thanks,
JC

Hello,

Yes, this generates the same .OUT file

I am using Widows 10  latest (OS build 19044.2006) in English

Thanks

Hi Nimrod,

Thanks. We'll run some tests and get back to you.

Regards,
JC

Hello,

Any updates ?

Thanks

Hi Nimrod,

One of the support engineers was able to reproduce the issue and the R&D team is looking into it now.

Thanks,
JC

Hello,

Any updates ?

Thanks

Hi Nimrod,

Not yet. R&D is looking at it now.

Thanks,
JC
