Assembler: Measurement across sweep vs leaf values

StephanWeber

Hi,

I am familiar with calculation across corners or across sweep, but I wonder about one thing:

I have one output, and run a sweep of VDD. To get the difference of the output CalibratedGain from run with 2.4V and 5V I can get a correct plot with this calculator expression:

leafValue( CalibratedGain "VDD5V0" 2.4 )-leafValue( CalibratedGain "VDD5V0" 5 )) => nice plot

I can then push this expression to the ADE output sdetup, but then a re-evaluate gives me an error.

Can I improve to avoid the error or use an expression vs sweep instead?

Bye Stephan

    Probably best to handle this via support because of being able to see your entire setup, but you'd have to (at least) set the EvalType to be "all" or "sweeps" to ensure that this measurement can be done once the sweeps have completed. If that's not working, definitely contact support.

    Hi 

    I have a similar issue with output setup. When I execute the expression from calculator it works. However, when I copy the same expression to output setup, it does not work (getting error or wrong answer in some cases.)  If you find the reason, please share it.
