    Closed: Re: How to Design a Meander Line in HFSS

    It is too complicate to draw it with an equation base curve I guess. Use instead the duplicate along line and unit options on your rectangles. Use variables intelligently to draw the antenna. You'll...

    Closed: Re: Tanner EDA : DRC Check

    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...

    Closed: ASIC Post synthesis simulation in VHDL

    Hello everyone,

    I'm new in the digital world. I'm looking how I can generate a VHDL file representing the cells of the PDK library.

    In brief, I've a RTL/VHDL code I synthesis with...

    Closed: Tanner L-Edit SPR Setup from an EDIF

    Hello everyone,

    I have an EDIF netlist generated from Leonardo Spectrum (Digital synthesizer).

    I try to setup the SPR of Tanner L-Edit with that file but I got the message : "There was no TDB...

    Closed: Re: HFSS error: Non -Manifold vertices found

    Non-manifold objects are objects with mixed dimensionality: for example a pair of 2D objects connected by a 1D line. Use the Model Analysis tool in HFSS to identify these erroneous objects (or simply...

  9. Closed: Re: What's the meaning of the Zo in HFSS? Is it characteristic impedance?

    I've simulated your CPWG design. I haven't changed anything and I get the results attached in the text file below.

    I use HFSS v13 however.

    Maybe you should try to refine your mesh, especially...

    Closed: Re: magnetic loss due to metal nearby

    In this system there is 3 types of loss:

    1. Eddy current loss
    2. Hysteresis loss
    3. Residual loss

    The current circulating in the metal plate will cause joule heat loss and this is called eddy...

    Non-manifold means that some geometries have mixed dimensions and cannot be manufactured. In your case you have a 3D object which touches itself at a point or edge, look at the picture bellow:

    Check the command .TRAN 0 1s 20ns in your spice netlist. It seems not correct. Your are set a maximum step size of 0s which have no sense.
