    [Moved]: [Cadence Virtuoso ADE Calculator] Difference between Freq and Frequency Function?

    Re: [Moved]:[Cadence Virtuoso ADE Calculator] Difference btw Freq and Frequency Funct 1. Looking at this thread (https://www.designers-guide.org/Forum/YaBB.pl?num=1234428781/1#1 ), I'm now confused about steady state. Is it that steady state means that the signal doesn't change with time...

    [Moved]: [Cadence Virtuoso ADE Calculator] Difference between Freq and Frequency Function?

    Re: [Moved]:[Cadence Virtuoso ADE Calculator] Difference btw Freq and Frequency Funct I've tried looking at "Design of Analog CMOS Integrated Circuits" by Behzad Razavi and googling, but haven't figured it out. Is it possible to please explain the general idea? My background is chemistry, so...

    [Moved]: [Cadence Virtuoso ADE Calculator] Difference between Freq and Frequency Function?

    Re: [Moved]:[Cadence Virtuoso ADE Calculator] Difference btw Freq and Frequency Funct Can you please explain why it isn't in steady state? The original signal from the ring oscillator is a periodic signal, so it should be in steady state. If it wasn't in steady state, the ring oscillator...

    [Moved]: [Cadence Virtuoso ADE Calculator] Difference between Freq and Frequency Function?

    Re: [Moved]:[Cadence Virtuoso ADE Calculator] Difference btw Freq and Frequency Funct I launched Skill API Finder, searched "freq", and read the results(please see 1st picture). The results are the same as the image of the user manual I posted in my original post(please see picture in original...

    [Moved]: [Cadence Virtuoso ADE Calculator] Difference between Freq and Frequency Function?

    Re: [Moved]:[Cadence Virtuoso ADE Calculator] Difference btw Freq and Frequency Funct Thanks!!! I tried out the freq() function, and see that it returns a waveform on top of the original signal. What does this waveform mean or represent?

    [Moved]: [Cadence Virtuoso ADE Calculator] Difference between Freq and Frequency Function?

    [Moved]:[Cadence Virtuoso ADE Calculator] Difference btw Freq and Frequency Function? I'm trying to find the period of a waveform in Cadence Virtuoso ADE using the calculator function. I see in the user manual that there's two things(please see below picture): (1) Freq function (2) Frequency...

    [SOLVED] [Cadence Virtuoso Hspice simulator] set equal time step in transient simulation

    Thank you so much Pancho_hideboo!!! You are a lifesaver!!! I am so grateful for your help. If there was a "King of IC Design" title, I think it should go to you. :)

    [SOLVED] [Cadence Virtuoso Hspice simulator] set equal time step in transient simulation

    1. In the "Hspice Time Step Options" and "All Hspice Options", I don't see the "tstep" (picture 1 & 2) and "delmax" (picture 2 and 3) options. I'm guessing I'm missing something obvious, but could you please point out what I'm not doing right? 2. I looked at the manual...

    [SOLVED] [Cadence Virtuoso Hspice simulator] set equal time step in transient simulation

    I'm using Virtuoso version IC6.17-64b.500.5. When i go to ADE>Simulator (1st picture), I don't see analog options. However, if I go ADE>Simulation>Analog Options, I see "Hspice Time Step Options" and "All Hspice Options" (2nd and 3rd picture). Do I click on the "Interp" in "All Hspice...

    [SOLVED] [Cadence Virtuoso Hspice simulator] set equal time step in transient simulation

    Where can I find the ".option interp" in ADE? The first picture below is the transient analysis setting, and the 2nd picture is the option setting for transient analysis. I don't see the ".option interp"? Thank you!

    [SOLVED] [Cadence Virtuoso Hspice simulator] set equal time step in transient simulation

    How do I set equal time step in Cadence Virtuoso's ADE transient simulation, when using Hspice as the simulator? I know that the Spectre simulator has the "strobeperiod" option, but the Hspice simulator doesn't (ref: https://www.edaboard.com/threads/125944/). I can't use Spectre, because I don't...

    [Virtuoso ADE Calculator] DFT function interpolation problem

    When using Virtuoso ADE Calculator's DFT function, it keeps giving this warning message that the sample points are interpolated, which may cause numerical error problems. I see that the x axis of the simulation points of the signal aren't equally spaced apart, which is probably why the DFT uses...

    [SOLVED] [Virtuoso HSPICE Simulator] Vpulse not working

    Hi, Pancho_hideboo! Thanks for trying to help. Someone else solved the problem, so here's the solution for others to prevent lost time/agonizing. Virtuoso is a GUI interface, where the netlists are generated with a click of a bottom (this is what's meant by automatically) from drawn pictures of...

    [SOLVED] [Virtuoso HSPICE Simulator] Vpulse not working

    1. In the Virtuoso ADE manual, it says that vpulse is included in the Hspice simulator, please see below (ref: https://studylib.net/doc/8875703/virtuoso-ade-l-user-guide) 2. I agree that the netlist using HSPICE is generated incorrectly, because it's missing the voltage pulse signal as...
