using output from one point sweep to another

RA202502215244

hi guys,

is it possible to transfer output from one point sweep to another at the same test. meaning that if i run sweep on variable "vcc_noise"=15m,-15m, then i can take the output expression value from vcc_noise=-15m, and define it as the output of the corresponding expression at "vcc_noise"=15m? or maybe i have to use 2 separate and identical tests, and implement it with calcval function?

Thx

    I think it's possible if you want to calibrate outputs between two point sweeps. Here is an example that works: 

    TestA : with variable sweep "vdc" = 2.5 and 2.7

    outputA : RiseTime
    outputB : calcVal("RiseTime" "TestA ?matchParams list(list("vdc" "2.5")) ?ignoreParams "rest")

    When you simulate it; 

    outputA and outputB will have the same value for point vdc=2.5
    outputB in the next point sweep (vdc=2.7) will have the value of outputB from the previous point. 

    Use calcVal wizard on the expression builder to write the expression more effectively. 

    Note: If you want to pass an output value from vdc=2.5 to a design variable in the same test, then it is not possible. This creates a cyclic dependency. So, it will be effective to add another tests. But, for outputs/expression it should be okay.

    Thanks
