different specs for a different input of a parametric sweep

mhkvy4

Hello,

I am using Cadence 6.1.8 release and I am using ADE Explorer.

I am sweeping the output noise voltage spectral density performance of my design for 2 different load capacitance values. Now the 2 load capacitance values have different specs with regards to their upper limit of noise that is tolerable. If I have the 2 loads within the same test as a parametric sweep, is there a way to setup two different spec for them in the same test?

Also how does the tol spec setting work?

    See this recent thread.

    As for a tol specification, this is described in the ADE Assembler User Guide, in the Chapter Working with Specifications. The first number is the target value, and the second is the allowed tolerance as a percentage. The output value must be within +/- percent of the target value to meet the spec, so it's another way of defining a range specification. This is also covered in the ADE Explorer User Guide, in the Specifying Output Data to be Saved or Plotted chapter, in the section headed Defining Specifications for an Output.
