    Matching shift during Ideal transmission line(TLIN) to microstrip (MLIN) conversion in ADS

    Discontinuities! When you generate a design with microstrip elements you typically need to add discontinuities, TEEs and CROSSes, to create the appropriate layout for simulation in schematic view, or for EM later. When using ideal elements there are no such equivalent components. There will be...

    ADS layout design

    Those are flight lines. They are indicating connections that are interpreted from the layout that no longer agrees with the element schematic connectivity, i.e., difference between schematic and layout. The clue is that you auto-generated the layout from the schematic but then made some changes...

    How to remove parse error in ADS2022

    You cannot edit the netlist file, but you can use it to identify the problem that is causing the issue and edit the schematic appropriately and then ADS generates a new (hopefully correct) netlist file when you re-simulate the design. Main problem is that you did not attach the netlist.log file...

    How to remove parse error in ADS2022

    Check the file called "netlist.log" in your workspace directory. This is a text file so it should be easy to identify line #7. Using the command "Simulate > Generate Netlist" in this schematic should open the default text editor window with this file to read.

    [SOLVED] Baseband phase noise plot ADS

    What do you mean by ideal mixer block? Do you mean the Mixer2 component? if so what do you have set as the mixer noise figure (default for this is 0db)? More detail about your test circuit would help to diagnose any issue.

    How to enable library in ADS2022

    As Volker says starting a new workspace would be a useful step to verify what may be happening. For the existing workspace what you show in the Manage Libraries UI is the wrong end of the list. You should look right at the very top. Typically, the analog_rf.defs is the first item and this is...

    Question about setting up parameters for impedance matching on ADS

    It is not possible to interpret what the simulation step size that you are using is (which would determine the number of frequency points) but it needs to be changed. A good starting point would be 101 points (Step-size of 30 MHz for 1GHz to 4GHz sweep) would give a smoother response.

    In Ads 2022 software, optim parameter is not completely visible to edit.

    You could always flip the screen, temporarily at least, to portrait orientation instead of landscape orientation. Easiest if you are using multiple or external monitors but it would also be possible with a single laptop screen but only if you have external mouse and keyboard in operation.

    In Ads 2022 software, optim parameter is not completely visible to edit.

    In its resting state a parameter that is set to be optimizable you do only see the nominal value and an indication of the optimizable style on screen: However, if you want to use on-screen editing simply go ahead and click on the parameter value. As soon as it becomes selected it shows the...

    Getting Optimization Error using ADS tool

    Looking at the first design, Optimization_L_C_R, there are many items entered incorrectly and a couple of these are blocking the simulation from working. In the second design, Optimization_L_C_R_Modi, you appear to have 'fixed' most of these issues but there is still one remaining. In the...

    Getting Optimization Error using ADS tool

    It is entirely appropriate to define multiple Tune/Opt/Stat/DOE Setup to a single parameter or variable. They are never all used at the same time, but each is active for the different types of simulation. So, ADS allows the user to enable all four concurrently, but the simulator only uses one at...

    Getting Optimization Error using ADS tool

    You initially reported that an error was generated when attempting to perform optimization for this design. I presume that now with better set-up for the optimization variables that this error is no longer the problem. Now you simply say that "I am not getting output" but this is not helpful to...

    Getting Optimization Error using ADS tool

    As Big Boss mentioned previously you are using the Tuning option in the Simulation Variables Dialog. You should have all these setting in the Optimization Tab (the second tab) to get optimization to work.

    ADS Layout - tune parameters

    What do you have set for the Order in the HB simulation? Your EM simulation frequency range must include all harmonics specified and not just the fundamental frequency.

    ADS - layout - generating schematic from layout

    Try doing something different at the other pin. The fact that you are relying on an area pin and not a point pin may be the issue. If you use a MTEE instead of that MCORN this would leave an available pin. Not is exactly the same position but it may give you results to get started. You could...
