Refer to another output equation in ADE

Grover

If I set up the output signals and expressions in Analog Design Environment, is it possible to refer to other expressions in an expression? For example, if I have the expressions

pin3 = (power from the 3.3 V supply)
pin12 = (power from the 12V supply)

can I then define

ptot = pin3 + pin12

in some way?

  • It works, some of the time. I currently perform a sweep of vin (input voltage) over 40 points. I then calculate:

    vout_av: (vout_av = (some stuff to compute the average output voltage))
    delta: (delta = (vout_av / 12))
    iout: (iout = (vout_av / 48))

    Now this almost works. Vout_av gives the correct value, a scalar voltage. Same for delta, it is a scalar voltage equal to vout_av / 12. However, iout doesn't work. It should be equal to a scalar voltage equal to vout_av divided by 12, but instead it gives a vector containing these values as a function of vin. And it does this for every point of the sweep! Now how can delta and iout be of different types when they have been defined almost identically?
