To help understand how to correctly assign spice models to schematic symbols for simulation, please have a read through the EasyEDA Simulation eBook at:

(The Google links above are to the original copy of the Simulation eBook which you can also find at:

but the table of contents in the EasyEDA copy is broken and misses out some sections. We are working to fix it but in the meanwhile the copy published to the web from Google Drive works just as well.)
Hi Jhonray,
Hmmm.
The AD8421 model seems to run without errors in EasyEDA but it looks as though the model itself is broken because when simulating the AD8421 usage as in:
`Figure 71. AD8421 Driving an ADC` of:
http://www.analog.com/media/en/technical-documentation/data-sheets/AD8421.pdf
it's output seems to be stuck at about 11.9V.
I have tried this sim in ngspice.com and LTspice but it gives the same results in those too.
I am investigating why at present.
Oops.
My mistake: I had accidentally reversed the -12V supply.
The AD8421 and the lower noise AD8429 models both work fine in EasyEDA.
AD8421 and AD8429 models are now in the main spice library.
:)
