  • (IC6.1.5.500.12) ADE L messing up sim results(result access). Anyone familiar with that?

    Dear All, I've done extensive searching on forum for this, in vain. However, I am sure that someone else came across this, and maybe my search keywords weren't appropriate. If you know of thread relating to this, please point me to it. From time to time I get the those symptoms (they might all...

  • Cadence 5.1.41 Spectre Error

    I am using Cadence 5.1.41 with NCSU CDK 1.5.1, and I am new to Cadence. I have created a simple schematic in Virtuoso. When I try to simulate the schematic using Analog Design Environment (ADE) and Spectre simulator, I got the following error. *Error* Errors encountered during simulation. The simulator...

  • Re: Running PSS for an oscillator with a driving signal in some other part of the circuit.

    Hi RF Stuff... Regarding: want to know whether hb analysis is suitable for hard-non-linearity (inverter based) oscillator as compared to an LC oscillator. If you have a semi-autonomous circuit (oscillator with a driven source), you MUST use hb with the semi-autonomous option. Only hb has the semi-autonomous...

  • Unified Reliability Interface (URI) without RelXpert?

    Hi. We would like to analyze the ageing behavior of our circuits runnig transistor-level simulations, but we do not have RelXpert licenses. Is it possible to evalute Unified Reliability Interface (URI) models in Spectre without using RelXpert? If yes, how can this be done? Thank you. André

  • spectre mtline connection problem

    When using mtline model in cadence spectre schematic simulation, why I can not connect output of one mtline to output of another mtline? (warnings show there will be short circuit and floating nodes)

  • Spice model in Spectre

    Hello, Andrew! I think, I have similar problem simulating the following model in spectre: .SUBCKT IPD100N06S4 drain gate source Tj Tcase PARAMS: dVth=0 dRdson=0 dgfs=0 dC=0 Zthtype=0 Ls=1.5n Ld=1n Lg=3n .PARAM Rs=659u Rg=1.3 Rd=50u Rm=180u .PARAM Inn=90 Unn=10 Rmax=3.5m gmin=60 .PARAM RRf=390m Rrbond...

  • Noise sources in PSS analysis

    Hi all, I have a pretty simple doubt. I am using Verilog A based circuit netlist to perform circuit simulation in cadence spectre. I have defined some flicker noise sources in the same netlist. If I simulated a simple differential amplifier, I can get the inut referred noise through noise analysis. Now...

  • Cadence user manual

    Hi, Is there any User manual for spectre simulations, where functions of each button and analysis , FFT, DFT, calculator ,etc have been explained. I was unable to find any document for such a very expensive Simulator. Just like LabVIEW they provide a very nice help and documentation for their customers...

  • Re: Problem in Cadence Virtuoso AC analysis

    Hi Andrew, I had a little doubt on what parameters are explicitly needed for ac analysis. This is because I am using verilog -A based models and hence want to be sure if I am doing the right thing. As far as I know, AC analysis first computes the DC operating point: so I must define current at each operating...

  • Re: Different op amp gains using different spectre analysis

    Thanks for reply, However I am facing a very strange problem in my simulation, please help me with this: I am running a parametric simulation to experiment & get the optimal bias current of Op-Amp . For this I gave a list of "I_bias" as "5u 7u " in the parametric analysis window...
