Dear all, I am a beginner. I need some opinion/help. Here is my situation. I am designing a transformer matching network (TMN) for a PA. I do not have ADS PDK but working in CADENCE PDK. My question is do I have to design layout in CADENCE then export gds file to E.M software such as hfss/ADS momentum for electromagnetic simulation and
DXF format is industrial standard.hfss will accept it..
Hi, PCB is designed using Altium software and now I want to do its EM simulation in hfss 16.2 software. Can anyone suggest me in which format should I export PCB layout from Altium software for the hfss? Please suggest !!!!
hfss supports the import of a variety of 3D files. If you have a 2D file (*.dxf possibly?) you could import that and use it as the basis for drawing a 3D model for simulation.
Hi All, I have designed my circuit layout in CADENCE and I want to do its EMI calculation in hfss-16. So, I have few questions regrading that: 1) When I try to import that file into hfss software then it directly opens into hfss 3D layout window. So, is it possible to open it into (...)
hello can anyone here please upload for me a layout for wilkinson power divider in hfss any design would be OK, i'm new to hfss and want to see how the layout looks like anyway my design is operating at 3GHz with equal P3:P2 lossy with lambda/4 matched Thanks in advance Hi, It's better if you can come with your la
Hello, I have been trying to characterise some IDCs using hfss, but I haven't got any luck confirming my results, in a way that I don't understand which is the correct way to extract the capacitance. What I have been doing is to draw a layout mentioned on a paper with the dimension and circuit expression as follow, and they calculated the ser
Hi Everyone, I'm having a problem on exporting the layout file from Altium to hfss. Anyone can help me on this? My PCB drawing in Altium was saved in .anf format and i'm struggling to export it to hfss.
Not in hfss. Don't know about autocad.
Hi there, Please what is the best way to transfer layout (projet in better case) designed in ANSOFT DESIGNER to ANSOFT hfss along with layer stack definition? Thanks a lot
Hi Vidhya, U havent mentioned if it is a planar or waveguide type of antenna. If its planar ADS is good, U need to define the substrate parameters and just layout ur design in ADS layout window..!! ADS is good for planar structures. And if its a waveguide type, den i suggest u try a fullwave simulator like hfss..!! So wt type of antenna (...)
Regarding the Airbox, please check the documentation for that, as I don't know hfss. I can't figure out the size of the patch and feedpoint from the image provided. You have a thin shorting pin, this reduces the resonant frequency, expect it to be below what you expect based on the formula from your first posting (Your text: "So, L1 + L2 = 14.
I have done this but over methodis bit long but it works 100% I have designed and fabricated many antennas now, hfss-->AUTOCAD-->PDF this is our method. From hfss convert design for autocad, then in autocad convert file to PDF then you can print it but be sure you don't do the scaling because It would change the design size.. -
Dear All, I've designed some antennas in CST and hfss software but I'm going to add some components to them. I exported Gerber files in CST from them. Now, I'm going to Import it into Altium Designer and add some components or modify the PCB layout. I tried several times but I couldn't. Would you please let me know how can I import and modify
Assuming I designed a microstrip antenna, filter, coupler or simular, and drew and simulated it in hfss, how could I take that to get a PCB produced by a commerical PCB manufacturer? Any suggestions for UK PCB manufacturers that can produce boards on Rogers or similar laminates at sensible prices?
The AutoCAD data exchange format for 2D layout is DXF. DXF can be imported into hfss and other EM simulators.
All this software is somehow useful for planar filter design, if you know the filter design methodology. hfss, Sonnet and CST can do EM simulation to analyze the layout when it is ready. ADS and AWR can do both: fast circuit model simulation to develop the initial layout, and also EM simulation to analyze the layout when (...)
See this Sonnet application note for a 900 MHz tag layout with extended bandwidth: What do you mean by "hfss S11 formula is wrong" ?
hfss is an analysis tool. It will analyze the filter if the layout already exists. If you start from electrical specifications, and do not have a layout yet, hfss is the wrong tool. Instead, use a filter synthesis tool ike Nuhertz Filter Solutions (commercial product) or Nuhertz Filter Free (free limited version).
***** I am desperate ********** I am simulating (hfss) an antenna working at 2.4 GHz (in its environment) and there is some DC voltage source to be included around the antenna Any idea on how to include a DC voltage source in hfss simulation? keeping in mind that I want the sweep frequency to be 2 to 3 GHz
I use Altium and therefor I am not all that familiar with Cadence. Do you know what files you are able to import into Cadence? if you know what files you are able to convert into Cadence I would be happy to convert your hfss design into that file format (My mechanical engineers work with solid works and that seems to be able to convert any format
Hello, I am working for Sonnet, so I do not have access to hfss and can not check your files. From the messages that you have shown, it seems that hfss has created DXF layers that are not mapped in your ADS layer settings (e.g. "Design_21"). To find out what layers are created, and what their names are, you can use some DXF viewer software or
Hi All I want to import .gds file from cadence 6.1 to hfss 10 and do some simulations. Just to make sure my gds file is ok I did import it back to cadence and I do see the same layout. But when I import the same gds file in hfss 10,I dont see anything. I am not sure what is the problem. When I look at my gds file its not readable. Please (...)
Hi All, I am trying a 2 turn spiral inductor and combine it with another 1 turn to make a transformer. I did a layout in Cadence and imported it in hfss only to find out it is of a "Non-Model" type so I cannot change its properties for 3D EM simulation. My inquiry would be, how do you make the parallelogram box in hfss? Seems like I can (...)
Hello, Just as the photo shown, I was design a LC-VCO at millimeter frequency, and I must get the accurate S_parameters or Q-factor of the IBM symmetric inductor, but it's difficult for me to model the inductor in hfss, for different parameters of the inductor, the different moder of ind I have to create. Could anyone tell me what to do? Thank y
Hi All, I imported a design from Cadence into hfss using GDS. Now my problem is I cannot see the coordinates of the geometric solid. Can anyone help me with this? I imported a transformer and I needed to add definitions for the silicon dioxide and substrate, which I plan to add in hfss since Cadence does not do this in layout. Thank (...)
Agree with covst. IE3D is more suitable for on-chip inductor simulation esp. with time-cost concerned. In order to design any octagonal inductor, I would suggest you to use IE3D. There you can design octagonals pretty easily and export the gds files to hfss. Then u can apply a z directional height to the layout to get a 3d oct
if your S11 and S21 are good result , but S22 and S33 are worng you must to check the isolation resistor(100 ohm), it placement between port2 and port3 about layer problem , you should chose the resistor size (0402,0805,1210...etc.)and measurment Port2 and Port3 distance and simulation of hfss,IE3D....etc. to check result.
I am trying to extract cadence inductor (UMC library) parasitics in hfss by importing gds file. After importing gds file, inductor layout is visible in hfss window with so many layers. Issue is that cadence generated 2D file and hfss want 3D file to simulate. I converted inductor 2D layout into 3D by drawing (...)
in SIWave you can simulate the PKG of a chip, you can use also hfss and Q3D from Ansoft. if you go for any of these directions, you should use the Ansoft Links tool to import your bondwires/solderballs/layout/etc. For higher freq you should use hfss, if your structure is electrically short (lambda/10 rule) you can use Q3D, both tools are 3D (...)
I am designing a filter by hfss and the filter has to perform as equivalent circuit layout by microwave office....... I want to plot the result of hfss and microwave office in one figure,but the data file from microwave office is not .s1p so it can not be plotted with result of hfss......... Can anyone tell me if (...)
The best tools in business are CST, Empire 3D, FEKO and hfss These are 3D volume meshing tools. They are good for some analysis, but not the best for everything. For planar analysis (PCB, LTCC, RFIC) the planar Method of Moment solvers like Sonnet and Momentum also have advantages.
Hi Everyone, I am not able to import dxf files into Ansoft Designer 4 or to hfss 11/12. I am getting the following error when I tried to import, using layout->Import File " viewport entity with no extended data" Any suggestions regarding this error? Thanks, sv
I desperately need to simulate this circuit using possible
hello, would anyone know how to effectively import a single layer layout file (dxf) into hfss ?
Ok thank you for your reply, My problem with the import of file, I have some design with hfss I would obtain the layout using GerbTool so I import the file from hfss (*.dxf) and I try to export it under GerbTool but I don?t obtain the desired layout (it give me only the substrate and the ground plane only but not the (...)
Hi, I?m working on a project in hfss but I have some problem to get the layout for PCB trace, generally I use word to design the PCB but if the structure becomes more complex I can?t draw it using word there is some technique or software to generate directly layout from hfss project???? Thank you for your help,
Dear all, Is there anybody familiar with simulation of a layout extracted from Cadence in hfss. Is there any voltage pulse generator source in hfss that we can use it with lumped port? Any comment is appreciated, Thanks,
Send your ADS design to the Momentum layout and save it as a DXF file(or what ever file format you can easily import to hfss). Now start hfss and look for that Momentum file. It should be straight forward. In Momentum go: "File"-->"Export" and pick the best format. Good luck.
Well I have converted the design made from hfss to DXF file and now I need to convert the DXF file to Gerber on Agilent ADS. I set the different colors on layout to distinguish the parts on DXF file but I would like to know more in detail as to what i need exactly on gerber file that is satisfy to send to PCB express to be fabricated.
I have used this tool for a while,and can't say it took my breath away. The biggest advantage is that it's an EM tool which work directly on your layout in cadence-so no need to do back and forth conversions (like say,importing to hfss or ADS is also pretty comfortable as a layout synthesis tool,as it draws spiral inductors and transf
Export the layout from cadence to hfss or from hfss to cadence.
Hi, I want to design a silicon spiral inductor and send to fabrication. Can anyone help me how to proceed.......... What should be the order of Design ............ (I have hfss) like, layout, Simulation etc.. First Do I need to start with layout or simulation in hfss ..... Does hfss support (...)
Is there anyway for directly extracting the layout from hfss? Thanks in advance
Hi, I've made some 3D designs in hfss and now want to export them for PCB fabrication. What I had done in the past was to use hfss -> SAT export -> AutoCad import of SAT -> DXF export -> ADS/Momentum DXF import -> Gerber export However, this doesn't work very well with what designs I have (the DXFs don't have gaps in the ground planes like t
DisplayPort is a new digitial display interface (VESA Announces Plan to Develop). I want to find it's layout file (such as *.sm3, *.hfss) that i can use it to extracte DisplayPort model. Could anyone supply it? Thanks for your help. Schematic structure as attached file.
I got with the basics but in designing the Branch Line Coupler, I am not able to find the formula for the width of the Branch Line coupler. The length is lambda/4 as usual. I'm using Ansoft hfss V10. I need the formula for the width of the strip. @gvinu4u: Because you got the basic principles of Branch line coupler, So
Hi I have attached a loop antenna layout. It is to be done on a PCB. Please see the hfss project file attached It is to work at 434MHz. I have the following doubts. 1. Do i need to have a ground plane. 2. How to exite the antenna. the input to the antenna is on the center
What kind of simulations?..hfss?..... could you show the layout?...
Hey you guys have been very helpful with most all of my project, I had a few question about designing PCB at RF freq. Are there any major advantages/ disadvantages? Also can anyone help to define RF design practices, the most of what I see is to keep lengths as short as possible, and watch out for running RF cables next to non RF cables. Thanks
