How to be sure that the SPICE simulation results are the exact results I will get when I build the circuit (especially an ASIC) in real?
I have been doing circuit simulation in HSPICE for research. The final stage of the research is to build an ASIC. The simulation results are often satisfactory. However, I am still in doubt if the ...

Can I set the channel-length of a FinFET to values very much larger than the minimum(or maximum) gate-length provided by the technology node?
I am using 14nm technology node in HSPICE. In the definition of the FinFET, there are two parameters 'lmin=10nm' and 'lmax=30nm'. Does this mean that I cannot set the channel-length to values larger ...

How to simulate noise in transient analysis of HSPICE?
How can I simulate the effect of different types of noise (thermal, flicker, jitter etc.) in transient analysis of HSPICE?
I want to make the sources noisy, make the FETs noisy.
The goal here is to ...
