run() & monteRun()

imagesensor123

 Hi all,

     for the same simulation, i have two process. the first, i set my model to the mc section, and i launched a simulation by clicking the "netlist and run" icon, we can get the result1(output curves). the second i also started a simulation from tools->monte Carlo, after configure the form, i triggered the "run" from the analog statistical analysis menus. we will get another result2. in special case, if i set the startIter "1" and numIter "1", can we espect that the result2 is the same with the result1? in another word, we choose "mc" section , not "tm" section in a classic simulation( from ADE window directly), is it a monte carlo analysis (just for one time)? one more question, could we change distribution method during monte carlo analysis? i didn't find any entrance in the analog statistical form.

 welcome to any discussion!

regards,

zfeng

  • Zfeng,

    You would not expect that a single point monte carlo would be the same as a non-monte carlo run. The non-monte carlo run will use the mean value of all parameters (those which have variations defined in a statistics block in the model files). The monte carlo run will be doing a randomization using the distributions defined in that statistics block, but only doing a single sample. The values won't be at their mean, but some random variation within the distribution.

    Assuming you're using IC5141 (you didn't say), you set up the distributed processing for ADE as a whole, not for just monte carlo. So you'd set it under Setup->Simulator/Directory/Host. If using IC61, you'd do this in ADE XL under Setup->Job Options.
