有人會用 BsimProPlus 嗎？

不知道有沒有人有 BsimProPlus 的教學檔？

那我要跟 Foundry 要什麼樣的資料才能在自己的電腦上作 modeling 以生成 spice model？

To extract SPICE model parameters for MOS, there are some measurements needed:
DC: at different temperature (basically low temp., room temp. & high temp.)
. y$ d3 c3 l7 V   Id-Vd under different Vg
   Id-Vg under different Vd (linear & saturation) & Vb
   Id-Vg under GIDL region (BSIM4)
   Ig-Vg (BSIM4)
, F4 E; l1 H7 f: i- MAC:
4 t8 l. H+ _' u3 B9 N& ~   Junction capacitance
, {, g. w/ p$ `   Intrinsic capacitance: Cgc, Cgd, Cgs & Cgb
. q" g3 J- t/ c: ~; ]8 ~   Ring oscillator speed
You can find all information you need in the BSIMpro+ user manual.   The most important, it takes much time for extracting accurate model parameters, especially for one who is not that familiar with model extraction.   The better way is to modify one existing model card with which the device performance is quite similar to the one you are going to extract.
Good luck & God bless you.
