the the learning problem I'm wondering skin and I will talk about competence spice modeling of all and its support for all fall so of the content to be so all previous speakers wherever wrinkle comp expire and spice modeling the last question by how he was also about the very log a standardization for Compaq of modeling so this is quite important part of the communication information exchange between different tools myself I'm also coordinating group this is group which mainly discuss competent and spice modeling model implementation standardization and the transistor-level assimilation we are organising workshops uh to discuss this topic so I would give you a lot of data on I'll even to have planning fall on in later this year I will start with small slow talking about Mike electronics so semiconductor devices you can to open the presentation was out of short that evidence the mall then I will golf rules uh and simulation and modeling in from all goal show you'll protease the got simulation Compaq modeling model standardization model implementation at this important part which we are not addressing curve of today it's parameter extraction and library generation tool interact between models of technology models and dynamic simulation and then this reference tool on the kind mainly on kind of her simulators 11 tool for uh quarks and then despise giving an example of of articles on each point and I would like to know all of the rise of open question about the integral part in there of of but I believe the but inlets standardization just small for out the communication information exchange between different tools I guess all flying
microeconomics and collect devices so 2nd simulation they already know this back in the sixties so Mr. more our lungs make uh echo close ended the density 0 for or number of transistors per chip and basically Dobel every tool tool years so in fact I don't like this observation because Mr. Moore and his partners intended use this lol tools have to be into the mean nation of IC manufacturing but there
is a positive element of moral and the very 1st integrated circuit was developed by the mean of Fairchild tho this is data about my bear visible bloopers to might my age but then very quickly over last fall almost fight case from fuel integrated transistor we came to let seconds which allowed to be at extremely cheap at what I am refering to this because hardware so cheap that we we can have basically any software running almost for free on this type of devices and I guess so all the faults and community the on this very cheap hardware developing they all tolls to date In this idea so the very 1st session of copter take tools say it follows them I want to go from this chain the we also of of a sentence of engineers will it cannot really manufacture integrated says it but we we can contribute to Protestant acknowledge optimization using can take up to some of the Apollo was refering to cut gender it's very sophisticated to be free be uh Protestant ecology simulation tools that of this seems also numerical modeling tools there is certain Cleese follow Francesco was refering to tools then this is important for complex modelling you can develop outstanding curve simulation tool but without most of its just numerical solver would you need a models FIL of circuit we all the real but Emile induced by squats but there are a couple of other the simulation tools and ideas this list is quite long for Compaq modeling all walls speakers wherever wrinkles Spice Verilog simulation model generation that tools which are supporting this of a lot of room attention was paid palladium as I guess this is 1 of the only tool to support this the transition from technological development compact models and then support simulation tools of more but it's like benchmarking platform it's I most was also mentioned here moppets new development that triggered by the hot or here in the US again we are talking about models but we need the parameters store and assimilation this part is not covered here but it's important and uh we should find a moment to discuss maybe and following
the uh some meetings so work so so this type of confidence brought assimilation again so we cannot fabricate it's quite complex but we can support the device development technology optimization this is a example of the the simulation of as some sense using co uh con gender 3 couples it's it's of free of GPO of software you can go quite complex sophisticated simulations they're sitting inside the example this is a to the simulation of mosfet the device and you can see the current flow and the mobility distribution this particle device this tool tools you input a compact modeling the beauty of models
or what is a compact model and so it's a a representation of a semiconductor devices so it's charges current and voltages we trying to goal from very complex numerical simulation tool simple analytical representation to preserve also device physics intensify teacup those this book tools for higher order mentioned there is some of course future development of commercial tools so they provide high accuracy but they are very slow because you have to solve for it to be a from a great tool calculate bias Thomas current and voltage compact so much simpler because we are trying to develop a simple equation which needs you dead of predict the behavior of the device and its analytical couple of lines of called it's much faster speed up research and on then of course you cannot use complex models analytical models for gate-level simulation because simplicity will have bn process that you cannot simulate consist of your appeal all my memory cell that at at this level so you go to the transistor but you need conduct models to create fair of empowerment libraries tool around these decimal we we are not called in this topic here and I guess both tools quarks and then despised on not on this level but they have the cargo assimilation of very look of digital all the age the the general so we have for spoolers also for at this level it's cute circuits and very fast similar coming to a surprise that the look Compaq modeling and simulation this book on uh behavior modeling with so they're very low language which it's about I guess like the 7 and already at that time there was some 1st post for standardization of delivered not if you borrow this book from the library you will find floppy hard to know if you remember what this property and its complete simulators by simulate order was very lock extension allows you Daisy semiconductor device modeling was very long local library set you would be surprised at the moment around all of the redefined so floppy but I did it and what there was a mix-up them tho I I guess it's about 2 thousand by guys from the University outcomes they do all which this 1 in of the other model delivery is this a similar
attempt was done by guys from q Bureau they simplify they create their combat modern libraries which talk to but is time the interface of different tools they simplify model synthesis and communication with spies up this
storm was sort of thing that I have I will not appeal but that at least in my opinion it's there on the open source tool supports very standardization I platform was sort their effort you you couldn't double check the references and marked tool still in use matlab but they are going to octane so this um development embattlement would be also based on free tools benefits I think so I did the continuity if we all around the and accept the very any all Verilog AMS other a stand up for competent to modern this would be beneficial to all who are within this uh activities so for model developers for software vendors so in fact the false development and despise clocks and other things we we can also interact with wafer fab and supporter of designers uses of power tools no the I will skip this
term and despised and plants was presented the hikes from sound the alarm also use Verilog standardization and they need they all modification to and the master oscillator so we we can exchange models so having quite model this model go to all the tools so good look up we we do
not have presentation I'm not communal got user but since to be but it's a really nice contrib module on the basis of Bayes gone from different plant genes and there is a global prior genes also supporting a numerous compilation device models and they have they all generator which depends on very low so that very locus like communication means so I minus 2 months at the end so again FIL golf ball process simulation modelling tool kompakt modeling we knew the internal parameters p when you have common data exchange format to talk from protease simulation tool support comic model development we need very Verilog standardization and they like model implementation In simulation tools here we have a bunch of simulation tools and and despise it's has very fast transient simulation but does not support that the come balance which is excellent feature of quot so to communicate when you a gain interoperability at that instant schematic the this this points where there are others that involve presentation and I want to highlight so we we need to a lot of work on standardization to improve information exchange between all the simulation tools which we are using the this is sort of final slide you can create there is serious of event's where we discuss combat modeling standardization on different occasions but if it's in Grenoble date you can visit Mosaik adopt or to the mall and we will continue this discussion because its kinetic out tool I have a small interoperability at different level of false tools in particle for of integrated circuits simulation then during which FIL B it the yes the 1 of the the that at the end of the year so the question was about the Verilog a standardization fault schematic this is a very important question but what will we do not have for a solution are there was discussion to use this type of high-level behavioral languages to describe not only devices but schematics or on that list our the all my ng spice use very I I I I can it's I don't want to say all but standard spicy input language which is a bit of the and clocks has its own so there's open discussion also within the industry to have more flexible input formats of form that Madison schematics and very likely very low could be a solution but yes please again the the comment was that the milk up but it's met this that I'm not to use the lookup user but yes so it very our our mean flexible tool and our is that's a lot of warping this kind of standardization to simplify our information exchange also than that the but you that
