Hi All, I am trying to use monte carlo simulation for a bandgap voltage reference. When I followed the procedure in this forrum and other tutorial, and click "run" for "monte carlo sampling", it looks like nothing was executed. I post my setup and hope anybody can advise about it.
1. I have a cellview named "monte_carlo". In ADE L, the simulation output is "\net55" and it runs well over temperature -50C to 125C (DC simulation in sweeping the temperature). I selected and set "tt" to allmodels.scs, and select "design.scs". After running sussceesully, I saved this state as "temp".
2. I open ADE XL->"create new view"->"open in 'new window'"
3. Create test and load the state "temp".
Now the setup looks like this [Since I cannot insert an imagine from my computer here, I created a same thread in another place. The setup file picture is shown in http://www.edaboard.com/thread281229.html#post1203445. Please kindly go to this post to see the picture, sorry for the inconvenience]
When I click "run", it never showed any progress. For example, I set number of points to 100, then it always show 0/100.
1.Could anybody advise how can I make simulation run? My target is to achieve some statistic distribution of output reference voltage.
2.Do I need to load more scs file here? like process.scs?
Thank you very much!
I doubt that's it, because it tells you before the run even starts if you've got a parameter or variable sweep with monte carlo. Also, it wouldn't explain why single run doesn't work because a parameter/variable sweep there is valid.
You can add a sweep in a corner - bring up the corners UI and add the variable you want to sweep, and set the value to start:step:stop (you can sweep in more complex ways). To be honest, the easiest is just to bring up the Corners UI (in the Corners section of the Data assistant, click on the pale grey line "Click to add corner" and then hit the Help button on the Corners Setup form.
