Hi David - You need to generate CCI (QCI) database from Calibre SVRF database (using Calibre Query Server - you need to have CCI license to do that), and use that CCI as one of the inputs when compiling QRC techFile. Ask Cadence for help, as these things can get tricky and might require Cadence support (especially so that (...)
I need transconductance parameter Kn of the NMOS and Kp of the PMOS . The amount of kn and kp for 90nm technology and 0.13un and 0.18un Tsmc company like. Thank you.
Hi I am using Synopsys design compiler as synthesize tool , I have pdk from a vendor that doesn't have symbol library then I can't do synthesize in design vision. is this library needed if I don't use gui and don't need to se schematics ? and is there any way to synthesize without this library ? (...)
hi I am working with 180nm TS18 pdk. Purpose is to swap body connections of PMOS and NMOS (body of PMOS to ground and body of NMOS to VDD) since there is no NMOS which has triple well, so I need to make it by myself by adding buried layer to the NMOS18 but then there will be a problem in LVS as there will be two extra how (...)
Hi If I want to be an Analog designer (Discrete or IC) how much device physics is needed? Already done a semi-conductor physics course, but not devices (i.e First 6 chapters of Neamen's book and an intro to PN junction). Do I have to take a device course in order to be good analog engineer? Level: Undergraduate Thanks.
This is done all the time, you just need to have two MOSFET models fitting the two species and link the symbol appropriately to the model for each instance (or, you make a symbol for each FET species that has a link to the proper model). If you were going to do this for reals you'd have a foundry pdk from a flow that offered such (...)
I need 65nm node technology files or less (28nm is preferable) for education purpose for cadence virtuoso. from where I can get those... kindly help me...
You need to scroll back further and address any complaints about libraries not found, failure of extract process, etc. I see some complaints about not being able to find what look like basic pdk library primitives, maybe your library setup is not making it to the verification tool's setup or something like that. Technology file (...)
A well designed amplifier -should- have trivial Vio variation with PVT and one which has any sort of autozero function may display no measurable Vio even with gross VT scatter. You need mismatch statistics enabled (by you) and modeled (by foundry, or roll your own) to see realism in Vio. The pdk docs ought to tell you the (...)
A bit more info would be helpful: show what you already have achieved, and describe exactly where or what for you need help! W/L ratios not only depend on process size, but also on the transistor models used. 180 nm cadence isn't enough, you should also tell which pdk you are using.
Hello, I am new to this TSMC 40nm pdk and they have plenty of device options. For example, for a 1.8V nominal vt device, I have options: nch25ud18 nch25ud18_dnw_mac nch25ud18_dnw_macx nch25ud18_mac nch25ud18_macx nch25ud18x I am actually trying to design an high speed op-amp and I am not sure about the difference between (...)
Cadence doesn't have any foundry technology; foundries do. If all you have is the generic, analogLib, basicLib then you will not find a layout for anything. You need the foundry pdk libraries, technology file / library, layertable and so on. The pdk ought to have docs that show construction. You evidently want a P+/Nwell (...)
Hello, To have standart cells, you need a pdk, from a foundry. If you have no access to foundry kit, cadence provides a generic pdk. All the informations you request are in the pdk documentation. Which pdk do you plan to use ?
i m in need of TSMC 500nm / plz help me
If the foundry demands a minimum density then they probably have provided in the pdk, their preferred density fill cell. This would have dense features on all layers. The cells can be left to float, or be tied to something benign (like substrate, where it will sit anyway, and substrate-potential metal if you feel the (...)
Hi.. i am using 28mn technology and have 900mV supply voltage.. i need to convert 0 to 800mV bias voltage into.. 200mV to 700mV i have 900mV MOS and 1,8V moses in my pdk.. which type of circuit shoul be used to achieve this..? thanks
Hi, I want to do the variability analysis on my design and hence I need sigma of vth and u0 (standard deviation of threshold voltage and mobility) for monte carlo simulations. I have the 90nm pdk as well, but I dont know where these values are written. Can you please tell me how to get (...)
Hi, I need the exact formula of calculating the capacitor value of Metal1 - Metal1, for example 90nm or 60 nm. Thank you
When I run PEX in Calibre I have a fatal error: Rules file must contain a CAPACITANCE ORDER statement. I'm a beginner and I need the PEX of an inverter layout! Thank you
I?m doing a Power module project, and need 47uH Isat>350mA SMT inductor for SiP. Where i can find the SMT inductor size for this project? Thanks.
I need to lay a standard inductor of TSMC 40nm pdk in virtuoso layout, I can't find a full inductor in 40nm pdk,but I can find full inductor layout in 90nm and .18um pdk. They just a unit or a part of inductor in 40nm pdk. Someone can help me?
So far as I know: 1. you need a pdk (process design kit) from a foundry. You have to sign a NDA to get the library. Otherwise, if you want to test and experience layout in L-Edit I suggest you to download Freepdk ( ). This is a pdk for education purpose. Once downloaded import the general GDS file in L-Edit. Yo
Sedit like cadence composer => need symbol , schematic library .. but many Fab only pdk .. some fab maybe have Laker UDD Tspice => just a spice tool , hspice , Tspice , dolphin smash , smartspice run spice model you need Fab provide process model file . Ledit => ledit can import GDS file to tdb , but no pdk like (...)
Min. gate dimensions usually correspond to the technology size. For reasonable design, simulation, ... you need to use a pdk which supports and is supported by your Cādence software. pdks are available from fabs/foundries (for production only), or from universities like NCSU[/URL
Hi all, I have been working on cadence virtuoso from the past six months. I have some basic questions on pdk ( process design kit). I read some answers which really confused me. 1.Some people say that fab provides the model files for the components and the eda tool just makes the symbol for that components and some features like (...)
Hello there, In IBM CMOS7RF 0.18um pdk, we need to put a "subc" in the schematic and put a "sxcut" layer in layout in order to pass the LVS. But in the digital standard library, the schematic views of the standard cell don't have the "subc" instances. So if I want to use a lot of the (...)
Depending on your pdk, isolated nmosfets probably need additional recognition layers to be recognized as such by the extraction tool. Read your pdk docu! If TSMC supports the deep nwell option in 65nm tech you should ask MOSIS or TSMC themselves.
Information here. There its says: The pdks are distributed by Triquint and are available for immediate use with the Agilent ADS software. To get access to these kits (and most other foundry pdks for any software
Well, it all depends on what do you need. If you would like minimum area then you must choose the one with the maximum resistance per square. (sheet resistance) Do you need positive / negative / zero thermal coefficient? and then there is noise and noise immunity. You better check you pdk documentation. (...)
... i need to know, the mismatch parametrics, namely Avt and Abeta. Mismatch parameters are process specific and have to be given by the fab/foundry. They should be available within their SPICE/SPECTRE simulation models in their pdk. For estimation values, see
Hi there, I need to incorporate a few custom designed transmission lines and inductors in to a TSMC 65nm tapeout. I found a document from another TSMC pdk about using Assura ?blackboxcell option to do LVS and RCX. The basic procedure is that you copy n2port element into the pdk lib and (...)
Still need help. Anyone can do this favor.
most pdk have only r and c extraction info. assura may not be able to find inductance related info in the kit for extraction. if u need u can add inductance to your signal path and check it.
I want to know what is technology porting from one technology to another . How this can be done.? What are the constraints and criteria that need to consider during porting of design? What are the drawbacks and advantages of porting? Can anybody help on this .. Thanks in advance
You need to add the file in which this model resides, to the Spectre libraries list. Or edit it into the default include-chain that is set up in the pdk.
hello all, many of u might working on UMC 65nm. i am working on current mode signaling scheme, trying to see the effect of scaling in CMS. for that i have to knw coupling capacitance and resistance for global wire(highest metal line that can be used for clock destribution). in my place QRC is not working for some reason. i need the data urgently.
what is the simulator you are running? Maybe you need a newer version of simulator. Try Ultrasim.
Dear all, I am using CMOS TSMC technology to design my circuit. Now, I need to use on-chip transformer. However, the pdk does not provide this model and I need to create it. If I am using ADS momentum, how could I do it? Could anyone introduce the tutorial, this teaches me to create 6-port transformer using ADS (...)
Hi all, I am working on a RF project. I am using Cadence Virtuoso 6.1. I need to know the threshold voltage(Vth) and gain parameter(K' = u. Cox) from a transistor model in a library of a pdk. For examle I am using Gpdk045, I want to know Vth and K' of cell NMOS1v. How could I do that? I (...)
Hi nanyac i need 0.15um GaAs Design Kit like "PL15-10 LN" for ADS. I need 0.13um or 90nm RF-CMOS Design Kit too. if you have each of them, i will be thankful if help me and send them to me. Best Regards
silvaco itself has all the tools you need. using tcad tools you can do the design of process and device and simulate both. look at silvaco web site. hock
i need some helps! i use IC5141 USR6 schematic editor and pdk symbols from TSMC. For P/NMOS transistor, I want to remove the bulk terminal since almost all MOS transistors' bulk terminal is tied with source supply VDD/VSS. so the circuit look simply if all MOS bulk terminal is removed. i want to create 2 new MOS symbols which have only (...)

1. you need a foundry pdk 2. a foundry pdk comes with a cds.lib which will contain default libraries and pdk libraries. 3. no 4. use installscape if you are a legal cadence tool user.
Hi Could any one help me and provide me with the UMC design kit (pdk) RF CMOS working for ADS 2009? Complete kit not only the models. Im currently working with a student project and need this for a LNA design, with front end simulation to back end layout , extraction and post layout simulation. (...)
Usually for pdk interviews, one does need to know something about what pdk is but is not essential. What I would say is a must is : Fab, little bit design (product definition to fab), layout and software development knowledge. Rest is usually learnt hands-on. All the best.
I downloaded the IBM 7RF pdk from the mosis websit and was wondering if anyone knows if we need a .cshrc file , because mosis does not provide one. If so how can we get one? I tried asking mosis for one and they did not give me one. Do we even need this file? Can anyone help? THanks.
Hi All, I have a questioned, 1. Where can we get layout databases (GDSII stream) which are free IP , that can uses for research, study and evaluation? Does any foundry, EDA firms or ARM provide such IP? Anywhere from 90nm --> 45nm. 2. Where can I download or get process development kit which is open for public? Let’s say I need some desi
I do not have the TSMC pdk as TSMC would not be my first choice foundry. There is an Open Standard Cell Library at is not exactly what you need but there is a variety of GDS layouts which can be sized to any technology and you can extract the components or use them as guides. If you cannot get
hi, I need Agilent ADS 90nm pdk kit. can anybody upload it on this forum. thanks sarfraz
