ADE: Use of nested design variables in output expressions

sommer

Hello,


I have defined the following design variables: (for sake of clarity I use the OCEAN syntax)

desVar(      "fin" 400M    )
desVar(      "Tin" "(1/VAR(\"fin\"))"    )
desVar(      "simTime" "500*VAR(\"Tin\")"    )

Now I try to plot an eye diagram using:

EYE = eyeDiagram((VT("/Vout+") - VT("/Vout-")) 0 VAR("simTime") ((2 * VAR("Tin"))))

#

#

it does not work. I get the following error message:

sevPlotAllOutputs('sevSession13)

*Error* ("eval" 0 t nil ("*Error* eval: not a function" (2 * VAR("Tin"))))

ERROR (ADE-1057): Could not evaluate expression

Name:'EYE'

Expression:'eyeDiagram((VT("/Vout+") - VT("/Vout-")) 0 VAR("simTime") ((2 * VAR("Tin"))))'

because of the following error(s)

("eval" 0 t nil ("*Error* eval: not a function" (2 * VAR("Tin"))))

Ensure that the definition of the expression is correct.

#

#

#

When I use only the variable "fin" in my expression, the plot succeeds:

EYE_EXPLICIT = eyeDiagram((VT("/Vout+") - VT("/Vout-")) 0 ((500 * 1) / VAR("fin")) ((2 * 1) / VAR("fin")))

Is there a way to use the nested variables in the output expressions?

In my simulation setup for the tran simulation I can use nested variables:

analysis('tran ?stop "1*VAR(\"simTime\")"  )

we work with IC6.1.6-64b.500.8

Best regards

Hans

    Hello Andrew,

    thank you for your reply.
    Unfortunately it does not seem to work even without parentheses.
    I have made some trials with the calculator:

    When I enter
    VAR("fin")
    it prints correctly 400M

    but with
    VAR("Tin")
    it prints the error in CIW:

    expression evaluation failed: Expression evaluates to nil
    expression evaluation failed: VAR("Tin")

    Best regards,

    Hans
