Simulating .cir file in PSpice for TI

Hi,

I would like to simulate .cir file directly using PSpice for TI. User's manual mentions batch simulation but user's manual that came with PSpice apparently describes some older version. So how çir file can be simulated directly? 

Thanks!

  • Hi Goran,

    Would  you please point me to the user's manual where it shows an older version of PSpice?

    Thanks,

  • Hi JC,

    Check the page 461. There is description on how to set up a batch mode simulation. One of the steps is:"Select Open Simulation from the file menu from PSpice window".. In FIle menu I can only open Project, Design or txt file. Also PSpice simulation window on figure 8-1 looks differently from the window I see when I start PSpice for TI. 

  • Hi JC,

    OK, I managed to get to PSpice window and to load cir file. However, when I start simulation I get the following error:

    ERROR(ORPSIM-16551): Floating point computation failed during Device/Model Load. Possible solutions: 1)Ensure that all device parameters are in valid range. 2)Try using .options LIMIT

    INTERNAL ERROR -- Overflow in device XU1.D_VCC_REG_D10, Divide

    I am simulating a power supply built around LM5176P. I double-checked circuit connections and found nothing suspicious. Any idea why this might be happening.

  • Hi Goran,

    This could be due to extreme value of certain component parameters. Please set the LIMIT option to something like 1E12:

    .OPTIONS LIMIT= 1E12

    Thanks,
