I think we need to change the model a bit before?enable it to work with LTSPICE, but I don't know how.? I compared, for example, the Id vs Vds?simulation, with?the manual from the vendor,?and did see the difference.

Hello All,
?
I am trying to use a HSPICE model (level=49)?that comes from the foundry. I didn't make any changes in the library file (the .l file) and used it directly in LTSPICE.? However, the results didn't look right when I compared it to the PSPICE.? The library I used for PSPICE was converted from the same HSPICE library and we have used the PSPICE library for several IC designs.? I assume the PSPICE library is correct.? The difference happens when I use the transistors in a specific bin.? For example, the calculated VTH is quite different.

What changes should I make before using HSPICE model in LTSPICE?

I looked at the error log file in LTSPICE.? It just showed the following warnings:

Thanks.
