Apologies for the long delay between articles (best intentions and all that). I last left you with an article about how to parameterize and manipulate device properties in your design without having to edit the schematic. A very handy feature. So there you are -- creating and matching and ratioing parameters willy-nilly. You've changed values and defined ranges and run sweeps.
And now you're wondering--how in the world can I keep track of all this information? How do I re-use a particularly good set of parameter values that I found during a sweep or optimization and run a Monte Carlo or Sensitivity Analysis on it or simulate it over corners? And while we're on the subject, I need different simulation settings when I run Monte Carlo as opposed to sweeps and corners. It's a pain to have to do all this hand-editing or reload old simulation history items to switch back and forth. What if I make a mistake?
Don't worry. There is a better way.
Setup states are analogous to ADE L states, only in this case they apply to the whole ADE XL environment -- multiple tests, specifications, sweeps, corners, parameters, setups for different run modes. All or any part of the setup can be saved to a setup state and reloaded fully or partially when needed for a later task.
In general, setup states are managed from the Data View Assistant. It's easy. Just set up everything the way you want and click RMB (right mouse button)->Save Setup State over the Setup State section of the Data View Assistant. A form will appear allowing you to name the setup state and select which elements of the ADE XL setup you want to be saved--Tests, Variables, Parameters, Run Mode, Run Options, Specifications, Corners, Model Groups and Extensions.
To load a setup state, expand the Setup State section of the Data View Assistant and click RMB->Load on the one you want to load. A similar form will appear allowing you to select which elements you want to load. At the bottom of the form is a little pulldown which lets you specify how you want the setup to be updated. I'll give a brief description, but the documentation walks you through a much better example.
Special Features for Variables and Parameters
Lastly, in IC 6.1.5 ISR12, there are some new features which make it easier to save and load setup states containing just the settings for variables and parameters.
Did you read that? You can do every analysis in ADE XL and GXL on any combination of device parameter and design variables values--without having to edit the schematic. That really simplifies "what-if" experiments.
