Changing the expression variable in regard to the parameter sweep in "output setup" in ADE XL

Hi,

I am simulating a variable BW filter in ADEXL using AC simulation. In this case, I want to check the spec in "spec" section. I have three control bits 1,2,3 and the corresponding ideal BW for them are 1M, 1.3M, and 2M. I have defined control_bit:1:1:3. I want to use only one expression for the spec to take the corresponding BW variable.

I tried using paramset like

pset paramset {

control_bit  BW_ideal

1                1M

2                 1.3M

3                 2M

}

However, I received the warning"  pset is not a valid parameter for an instance of 'ac'. Ignored."

BR,

Nami

  • It's not clear to me where  you created this paramset or how you referenced it, but I very much doubt it's what  you want.

    What you probably should do (provided  you're using at least IC616 ISR9 or later, when variables in specifications started to be supported) is to:

    1. Set up your variable control_bit to be swept in ADE XL as 1:1:3 (as  you did before).
    2. Add a new global variable, BW_ideal and set it to 1M,1.3M,2M
    3. Select both control_bit and BW_ideal in the global variables and then Right Mouse->Group as Parametric Set (this will change the colour of those two variables to show they are grouped - it won't run 9 simulations, but 3)
    4. In your measurement, set the specification limit to be VAR("BW_ideal")

    Hi Andrew,

    Your solution worked perfectly! Now it takes the corresponding BW_ideal variable at each control_bit value.

    The paramset stuff I used earlier for the transisent simulation and was working fine. It was defined it in "additionalParams" section and I had assumed would work for AC but it didn't (maybe due to another reason or a wrong setup)

    Anyway, I was not aware of this option of "group a Parametric set"
