How to run the spectreS Simulator faster ?

Riccart07

Hi all,

I am simulating an ADC in the goal to calculate the FFT.
I am using a sine wave as an input(Fin=10Khz). Each conversion takes 6.5us and I would like to run for 6.7ms. Fsampling=154Khz
I am using the spectreS simulator and now, the simulation takes at least 2 days and more.

Does anyone know how to fix the step in the order to get faster simulation ?

Thanks for your help !!!

     Thanks for your response,

    I am using this version of spectre: sub-version 5.10.41.102808

    I am trying to do a long simulation like 6.6ms. After 976.254us, i got this message.

    Error found by spectre at time = 976.254 us during transient analysis `tran'.
        SST2 Error: No space left on device

    Analysis `tran' terminated prematurely due to error.
    finalTimeOP: writing operating point information to rawfile.
    Trying `homotopy = gmin'.
    Trying `homotopy = source'.
    Trying `homotopy = dptran'.
     

    Error found by spectre during info `finalTimeOP'.
        Unable to start type table in the PSF file `finalTimeOP.info'.
     

    Error found by spectre during info `modelParameter'.
        Unable to start type table in the PSF file `modelParameter.info'.

     

    Do you have any idea ?
