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:
?
Ignoring BSIM parameter CALCACM
Ignoring BSIM parameter SFVTFLAGl
Ignoring BSIM parameter VFBFLAG
Ignoring BSIM parameter XL
Ignoring BSIM parameter XW
Ignoring BSIM parameter TLEV
Ignoring BSIM parameter TLEVC

Ignoring BSIM parameter LDIF
Ignoring BSIM parameter ACM
?

Thanks.
