Hallo, While using si pi pro in ads 2019, i get an error  exception caught in fem_process: source < c6> is isolated from the problem domain. Make sure that the source is not defined along a PEC object and it is not within an unmeshed metal. c6 is a capacitor which is connected between the board ground and ground. However, in ads2017, this… (Show more)

Hi,   I am trying to make out how the communication channel works in the example - UWB_PULSES. In the help there is very little information about the PropagationLoss block. Can you tell me an article or book that describes the mathematics for the description of the channel?   In the help there is very little information about this example and… (Show more)

Hello. Is there a quick to re-simulate or reuse the data from the previous simulation if only new ports are added or a current port is moved on a pad? It seems like a waste of time to have to go through the entire simulation again.

I have a question about EM simulation accuracy. I'm working with a very simple layout to learn the Momentum portion of ADS. The layout is just a ground plane with a transmission line on top. With default settings of 20 cells/wavelength and transmission line mesh unchecked my S11 or S22 show a high inductive component of the impedance. All other… (Show more)

Tips: Importing a Cadence Allegro *.brd file into ADS requires an Allegro utility called "extracta". Please make sure that a Cadence Allegro PCB Designer installation is available, and that the location of its "extracta" executable is included in the ADS $PATH environment variable setting.   Q: Cadence Allegro PCB has been installed, but how to… (Show more)

Hi,  I am using Linecalc for optimization. I receive a warning saying that "there's an error" . However, I could not find any text  indicating these errors in the hpeeofsim window. A snapshot is attached below. I could see the values of W, L updated due to linecalc operation. However, I would like to know if there are any errors. Can someone help… (Show more)

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 for every port when I import a layout from ADS. Is it possible to do this from ADS so that when I import, all the ports are imported as a lumped component? I am… (Show more)

I am using RFAMP component from 'RF Design Library' in system vue. I want to define this amplifier as low noise amplifier (LNA) by defining its s-parameter values and noise figure at operating frequency.   But no option is available among parameters for this particular component. How can I add s11,s21,s12,s22 and NF values for RFAMP component.  … (Show more)

Hello,   I am designing a simple open stub filter which suppresses 2nd and 3rd harmonic frequency and gives a required value of Zin at the operating frequency (or first harmonic) using two quarter wave open stubs designed at 2nd and 3rd harmonic frequency respectively. The schematic has 8 parameters, which I can TUNE to get the desired response.… (Show more)
