Pspice Advanced : SMOKE. Different smoke limits per Model

Dami

Hi,

 I start with the smoke analysis and I do not manage to create 2 resitances with different properties.

I am used to add Rbreakout resistors and to Edit the Pspice Model in order to give them different DEV (for example 1% and 10%) or TC1.

Now I would like to perform a smoke analysis on my design? is it possible?

The "part" VARIABLES in PSPICE_ELEM library defines all the smoke limits but there are the same for all the resistors....

Thanks

  • No I did not change the Resistor from PSpice_ELEM.

    I have a schematic with several AD587U, op97, and resitors. 

    I have modified the AD587U/AD in order to have Monte Carmo analysis in Pspice.
    I create the RMODEL above to have a model conform to the datasheet i.e. 10V+/-5mV.

    I didn't realize that PSpice Advance Analysis and Pspice A/D were 2 separate software.
    I just notice that when I select "Enable PSpice AA support for legacy", then the PSpice A/D result are wrong.

    I perform a Monte Carlo with  DEVTOL=0, DTEMP=0, DMONTH=0, PSpice A/D show me a histogram with the output always equal to 10.0V.

    I perform a Monte Carlo with  DEVTOL=1, DTEMP=10, DMONTH=60, PSpice A/D show me a histogram with the output which vary between [9.982 and 10.018]. That's Ok.

    I perform a Monte Carlo and i select "Enable PSpice AA support for legacy" with  DEVTOL=0, DTEMP=0, DMONTH=0, PSpice A/D show me a histogram with the output which vary between [9.995 and 10.005]. That's Wrong.

     

    Thanks to your help, I now manage to have a SMOKE analysis.
    In the Pspice Advanced Analysis Interface, I am not interested in some parameters (for example "Maximum current" for a capacitor) but some other parameters (like the "Maximum temperature" for a capacitor) are not visible.
    Is it possible to choose?

    I just hide the "Max current" by filtering but I do not have the Max Tem on capacitors and I have it on the resistors??

    And is it possible to extract the results to present them in another report ( something like a Copy to clipboard?)
    Because the interface with green histogram it really intuitive!

    Thank you
