"Error:Error:Fails to write LTD file to disk" Also attached error image for your reference. Problem with the number of phase fronts when attempting to generate OAM: In brief, an OAM (Orbital Angular Momentum) beam with a specific mode l should present exactly l number of helical phase fronts in its radiatio... I want to simulate Transmission line in ADS momentum for that I'm trying to use substrate ,which I got from technology library(65nm TSMC) as a LTD file which I'm able to import in ADS momentum "substrate editor" but I... What is maximum frequency we can simulate in Sipro Hi everyone! I'm trying to simulate a pair of microstrip coupled lines, to determine its odd mode impedance and differential impedance, using ADS and, eventually, Momentum. In the end, my point is comparing si... Could someone please show me how to properly define the ground plane in the substrate definition of Momentum? I am trying to do a simple simulation of a 28GHz 50-ohm microstrip/stripline in ADS and compare the S... Hi im interested to adquired a ADS License but i wanna know how much it cost for a studen somebody can help me? I'm having a problem using adaptive frequency sweep. The rational fitting model sometimes does not select enough frequencies to accurately model the structure. The S11 plot below shows where I am getti... Hi i want to know how much it cost a studen license , and the type of support that give a student EMPro Python Scripting: 1. Can EMPro print a report of a design's parameters? If no, is it possible to use Python to print a report of a complex design's parameters? 2. Does EMPro perform design Optimization? If yes... Want to write python script to get plots of axial ratio in dB, S11, and smith chart of antenna design. Can you help? Currently takes ~ 8steps to manually drill down to result's AR dB, and that's PER result. W... Hi, In EMPro, I usually create a circuit component definition (R,L,C) and assign ports to that definition and select 'not a port' option. However I need to do this every time and fo... I'm exporting a PCB design from the Cadence Allegro to ADS 2017.1. The design is a 10 layer board with RF and digital section. I removed the digital fraction so only RF components are remained. Moreover I only export ... Hi, New to EPpro. I noticed I never get a warning or error message if I overlapped two pieces of different materials, such as AL and Cu, PVC and FR4, etc. The simulation goes on without a hitch. It'll sta... GCPW simulation @ 70GHz. hello all, I'm currently doing simulation of a GCPW line at 70GHz. But I recently a testboard and the results is far from the simulations. AFter investigation I suspect some atmospheric... Hello, I have been running EMPro 2017 on RedHat 6 for a while. Recently, EMPro starts to crash fairly often. Most of the CAD Tools (such as ADS, Cadence, Matlab) generate a core dump file when they quit. Does EMPro a... I generally use ADS momentum for circuit design, not used it for Antenna, I usually use HFSS for antenna. I was comparing the results of a microstrip resonant patch antenna designed in HFSS with ADS and EMPro (F... Hi, Does anyone know why emds_mesher.exe does not use much processing power? I am simulating a fairly big object that has more than 30,000 faces, but it takes forever to finish generating the mesh. Is... Is there a way to view or save the non-interpolated S-parameters of an EMPro simulation? I've attached example screenshots below where my simulation "converged" from approximately -80 dB isolation to around -2... Hi, I keep getting this error message after refining. It says: Attempt to write a read-only database, which doesn't make sense to me. Does anyone know how to fix it?
