I just want to understand the capacitance such as cdd,cddbi and cjd,cjs.I know that the simulator Sprectre of Candence uses BSIM model and I have already downloaded the BSIM3v3 manual reference.But I could not find the parastic capacitance I mentioned above.Thank you

Thank you very much.From your answer,I learned that such capacitance as cdd,cddbi and so on are just the capacitance to constitute the correct SPICE models.However,I still have two another answers:
1.I have just downloaded the BSIM reference manual and found a lot of capacitances such as CGS0,CGD0,CGB0.But how did the capacitances showed in Candence Sprectre to make up the capacitances demonstrated in SPICE model.Did you have any documents introduce this?
2.I have learned form your answer(I mean the last sentence)that maybe I could able to control the simulator not to print out all the passive elements inside the transistor model.How could I do that?
Very looking forward to your answer and thank you very much.
