如果跟 Foundry 下 testkey，想自己作 device modeling（有特殊考量） l( q" V3 y" x/ ?0 B; p' D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？ / ~; Z+ n( O6 \ 3 |$ d6 Y* h% Y. M現在一團亂啊....麻煩大家了！！作者: cas 時間: 2008-1-26 08:05 PM
there are some pdf documents in the intall directory of bsimpro & q! z0 w1 Z4 R1 C" w0 Kone of them will guide u about what to measure before creating a spice model作者: j5739792 時間: 2008-1-28 10:58 PM
To extract SPICE model parameters for MOS, there are some measurements needed:+ ]8 H Z% ], B; C* b

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.6 \/ A- s4 L! I6 W& n; J
