From tsmc manual, I find this "The designers will need to turn off (mismatchflag=0) or turn on (mismatchflag=1) in the macro model for nominal or monte-Carlo analysis". Any idea, how can I turn it on?
i want to run a monte-carlo simulation for transistor mismatch in Hspice, i find this cod for monte-carlo simulation in hspice manual, .TRAN 1n 10n sweep monte=val .PARAM xx=GAUSS(nominal_val, rel_variation, sigma <,+ multiplier>) but i don't know the amount of rel_variation and sigma for tsmc 0.18 (...)
Hi everyone, Has anyone had experience with post layout mismatch monte-carlo simulations with tsmc kit? I am using the 65nm process and is unable to perform the post layout mismatch simulation. I am able to do the mismatch simulation in schematic. However, when I tried to extract the parasitic capacitance using Calibre PEX, I have the following
Thanks for reading the question. I want simulating the monte-Carlo simulation in tsmc process(65nm). But i want just mismatch factor(inner die or inner wafer variation) in the simulation, but don't want include the process skew - such as TT/SS/FF. When i look at the model parameter, it has several selection items but i cannot find what i want.
Hi, I'm using 130nm tsmc monte carlo simulation. In their rf013.scs file, there is a mc section for monte carlo. There is also nch_mis/pch_mis for mismatch nmos/pmos transistors. I'm just wondering what the purpose is for the mc section if I am using nch_mis/pch_mis cells in my netlist. Thanks. SC
Hi all, I need the model file of tsmc 90 rf for monte Carlo analysis in Cadence (spectre) Can someone provide me with the information of where I can find it? Thank you in advance, Vasilis
When I simulate the comparator offset, what percentage of input diff pair mismatch should be set? And what is the typical value of offset when using tsmc 0.18um technology? Thanks!
Dear all, I would like to run monte Carlo Simulation in ADE cadence! tsmc 035um However when I run it showed this message: "mc1: Attempt to run monte Carlo analysis with process and mismatch variations, but no variations were specified in statistics block." I dont know exactly how to do simulation! If you know, please guide me. (...)
You have the tsmc 0.18 model card? It has monte Carlo.
yes, it is cadence. and i am using tsmc mix signal .35
you can get the monte carlo model from tsmc.
Dear All, I am using tsmc 0.18um design kit. there are two models for the nmos/pmos transistor, one is normal and the other is named "mismatch model" ( in the tsmc18rf lib there are 2 transistors nmos2v and nmos2v_mis ). Which one should I use for monte Carlo analysis? I tried the two, the mismatch model gives wider spread ( larger (...)
tsmc 0.18u only has MC analysis for transistors. 0.35u, 0.13u, 90nm all have MC analysis for the whole kit, but not 0.18u. Atleast this is with the tsmc kits I've used...
Do monte-carlo analysis. Foundry like tsmc includes monte-carlo analysis in their model files. If your foundry does not provide then you will have to write it yourself. An easy way is to add a voltage source for each MOS, which will emulate the Vth mismatch. Then you should write a script where you will include the value of standard (...)
