Too many Point Sweeps (>1 M) for ADE XL to handle

FormerMember

Hi,

I'm new to ADE XL, and  not sure whether I am asking a dumb question..

I'm trying to use ADE XL to sweep a parametric set of 10 variables, each having 5 values to sweep over. So effectively there should be only 5 runs of simulation. However, the "Run Summary" shows there will be 9.765625e+6 (i.e. 5^10) Points Sweeps which is over the hard limit of 1e+6. So cannot launch the job (Single Run, Sweeps and Corners), as below:

I am pretty sure I have already grouped the 10 variables into one parametric set. When I reduces the number of values per variable from 5 to 3 (thus the total point sweeps is now 3^10=59049 <1e+06 ), the job can be launched, and as expected only 3 runs of simulation.

I cannot believe ADE XL cannot handle the above simple user cases. So what mistake do I make? Thanks for help in advance!

    Which IC subversion (Help->About tells you this) are you using? It doesn't happen with the current version (IC618 ISR11) so I want to check with whatever version you're using (in case it has something to do with the submit point being enabled, which isn't present in current versions).

    Andrew.

    Hi Andrew,

    I am using IC6.1.6.500.14

    Thanks!

    I just tried in that version. I created a bunch of variables (with 6 sweep points in each). If they are not grouped, I get this:

    There's no highlighting of the variables - the background is white, and you get the huge number of point sweeps. If  I then select and use the right mouse button menu:

    Having done this, you see the grouped variables highlighted in the same colour (note the bottom variable is not grouped):

    As you can see, the number of point sweeps is dropped. However, your UI showed something about a submit point.

    So, if you go to the "gear" icon next to the run mode, and then click on this Override Active Setup:

    If you do that, it then ignores the group as parametric set (the sweeps are defined in the "Specify Points" UI).

    Note that the same problem occurs in the latest versions too - if you override the active setup from the Single Run, Sweeps and Corners options form.

    So go to that form, and turn off the "Override Active Setup". If you really need to override the setup, you can use the "Setup States" to save a set of variable sweep settings, and then load different Setup States to switch between them.

    Regards,

    Andrew.

    Thank you so much, Andrew. Now it works, exactly as you said!

    Appreciated!
