Hello All,

I am adding new model into LTspice for TI LM25184_Q1 part. I have downloaded model online but there was no .cir in model files on TI site.

So I simply changed extension .lib to .cir and was able to generate and place symbol in LTspice schematic. However I am getting below error when trying to run simulation.
"lm25184-q1.lib(484): Expected device instantiation or directive here.
$CDNENCSTART_ADV2"

There are multiple error for Multiple line# in .cir file.

I suspect my method of change .lib to .cir is wrong.

Note - All .cir .lib and .olb file are located in same folder as LTspice simulation schematic file.

Cheers,

 

Quite often TI models dont work with LTspice, since they are written for "PSpice for TI" which has a slightly different syntax. Try to download and install PSice for TI.

 

Do you mean use TI's own simulation SW ? TINA?

 

hi may,
Clip.
Texas Instruments does not officially provide an LTspice model for the LM25184; they only supply a PSPICE model. You can download the native PSPICE files from the Texas Instruments LM25184 Product Folder, but running encrypted vendor models directly in LTspice often throws formatting or encryption compatibility errors

Thanks Eric.
I think that sums it up for this issue.

No, https://www.ti.com/tool/PSPICE-FOR-TI?keyMatch=pspice for ti download&tisearch=universal_search
But I think you have to register an account at TI.

 

if you get around at LTspice -- then i have revised/revived for LTspice few simple P-Spice device models by
1 ) - renaming cryptic non-LT' compliant nodes
2 ) - renaming non-LT' compliant std. devices
3 ) - (just incase) renaming I/O ports
(4) ) - misc. minor revisions at suspected places

however at LTspice many Pspice models exhibit extra sensitivity - and may need external elements to attenuate and or slow down the signal transitions

... means - such can be done - but for a complex mixed mode device it may not pay off your effort

I tried same model from TI in LTspice. I am having issue with it.

 

Yes, because it is an encrypted model. Encrypted PSpice models don't work with LTSpice. As already mentioned: for this model you will need "PSpice for TI" or the original ORCAD PSpice, which is $$$.

 

Ok I got it now.
I will stick to Eval kit maybe.
Thank you for your help.
