  1. Closed: Re: Simulation discrepancies between Sonnet (standalone) and Sonnet Cadence Interface

    So hypothetically, if I remove the feedlines in SCI (only the oval shapes are left), will the simulation results be the same with my previous simulations in Sonnet?




    Speaking of which, these...
  2. Closed: Re: Simulation discrepancies between Sonnet (standalone) and Sonnet Cadence Interface

    there are arrows in all inductors in xgeom, in fact, all of them are synthesised by your spiral inductor assistant and come with the arrows by default.

    Besides, in SCI, I've taken...
  3. Closed: Re: Simulation discrepancies between Sonnet (standalone) and Sonnet Cadence Interface

    The feedlines are the same as I imported their gdsII from Sonnet.

    not sure about the de-embedding settings and different equations, may I know where to check it?

    (edit: the equations I used are...
  4. Closed: Simulation discrepancies between Sonnet (standalone) and Sonnet Cadence Interface

    Hi,

    As per title, I am simulating four custom inductors that'll operate at their target inductance at 60 GHz. All simulations are satisfactory when using Sonnet by itself, however when I...
  5. Closed: Questions in manually creating substrate files for Sonnet Cadence Interface

    Hi everyone,

    I've successfully simulated several inductors in Sonnet and is moving on to re-simulate them using Sonnet Cadence Interface and integrate them into my LNA in Cadence Virtuoso for...
  6. [SOLVED]Closed: Re: [DISCUSSION] Maximum ram usage for Sonnet/HFSS simulation

    Agreed, especially when I have only 4GB of soldered RAM on my laptop, I had to configure my simulation to output relatively accurate results while using just below my RAM limit. Compromises had to be...

    Wow, that's an impressive amount of RAM, and even that was still not enough for you! May I know how large is the structure?
  8. [SOLVED]Closed: Re: [DISCUSSION] Maximum ram usage for Sonnet/HFSS simulation

    Thanks for the reply! I'm aware that I can reduce RAM usage by using conformal mesh and increase the size of the mesh, I'm just curious whether anyone here had hit high RAM usage for their projects,...
  9. [SOLVED]Closed: [DISCUSSION] Maximum ram usage for Sonnet/HFSS simulation

    Hi, I'm just curious, what are your maximum used RAM for the projects you've been simulated for either/both software?

    Is it possible to achieve extreme RAM usage, like 64 GB or above for a single...
  10. [SOLVED]Closed: Re: Questions for Dr. Mühlhaus Spiral Inductor Assistant for Sonnet

    Say I created four single-turn round (stadium) inductors to operate at 60 GHz, all within 68 pH to 104 pH, and I've simulated them with Sonnet, they somehow reached my targeted inductance with decent...
