[SI-LIST] Question about AC analysis for weak inversion MOS using HSPICE

Dear all,

As well known, the SPICE models such as BSIM3 and MOS9 don't fit the 
characteristic of MOS transistors in weak inversion region very well. 
However, I am sure the transient simulation is reliable for MOS transistors 
in weak inversion region using HSPICE. Who can explain for me whether AC 
analysis is reliable for transistors in weak inversion using HSPICE?

Thank you.
