  • Re: Ultrasim: individual accuracy setting on subcircuit level ?
     Hi Andrew,   Thank you very much. Found it and trying it right now.  However I'm puzzled by one simulator output. Even though I set one instance to df and one to s the device model statistics reports only devices set to spice. Shouldn't there also be devices listed that are set to df ? I'm using MMSIM ...

  • Ultrasim: individual accuracy setting on subcircuit level ?
    Hi all,   I'm currently simulating a big mixed signal block, consisting of two big blocks. The instance block I0 is pure digital logic, instance I1 is mainly analog but also includes some digital parts. I'm using Ultrasim for verification but due to the analog parts I'm forced to use a quite strict accuracy setting to get ...

  • ADE XL: Strange Behaviour of Measurements in MonteCarlo Mode
    Hi all,  Yesterday evening I moved a simulation from ADE L to ADE XL to perform some MonteCarlo runs. As usual I imported the testbench settings into ADE XL and made a quick nominal run to see if all my measurements still check out fine. Everythink was ok, therefore I moved on to MonteCarlo Mode. And here the strangest thing happend. ...

  • Re: Design variables in FFT and THD measures
     Hi Andrew,   Thanks for your assistance on the matter. I have tried the famMap() option but I still get the same error messages. As soon as our local contact for Cadence is back I'll ask him to bring this in to customer support.   Best Regards   Andi

  • Re: Design variables in FFT and THD measures
     Hi Andrew,   Thanks for the hint, however it's still not working. What I have tried: I use the same set of three variables sigfreq = 256k startint = 5u stopint = startint+5*1/sigfreq  Staring from  thd(v(.....) 5u 24.531u 36000 256000) I replaced the frequeny setting 256k for the THD measurement with ...

  • Phase Noise at PIO vs. Parameter
    Hi there, I'm simulating a VCO at the moment and I want to create a plot which shows PhaseNoise@100kHz vs. tuning voltage of the VCO. However I'm having trouble in getting the plot.The simulation is a PSS simulation with PNOISE that uses a symbolic parameter that tracks with vdd to ensure that vtune does not exceed the supply ...

  • Re: Measure leakage current
    Hi, In general I would set static operating conditions and measure the gate current and the currents in the supply of the NAND. If you want to get a more detailed view you need to probe the individual currents of the devices within the NAND, e.g. IGD,IGS,IGB for all devices and IDS for the closed devices. This should give you a pretty good ...

  • Re: save all device data in dc sweep
    Hi Josef, Sorry, I can't help you out at the OCEAN front as I don't use OCEAN that much. I just know that you can include the additional file by adding stimulusFile( ?xlate nil "path to new include file") to your existing ocean scripts   Maybe some other guys can help out here   Best ...

  • Re: save all device data in dc sweep
     Hi Josef,  Here we go:   Create one additional file to include with your simulations and fill it with some lines like   save DUT.MP0:oppoint save DUT.Q0:oppoint   and so on ... of course you have to adjust the hierarchy information andthe devicenames   If you enter "spectre -h save" you will get ...
