Syntax in ADE output expression for finding the minimum of two or more numbers

Dear yxie,

yxie said:

An output "A" is defined and its value is returned (i.e., updated, refreshed) per Spectre simulation run. Then I want to define another output "B", whose value is the smallest of output "A" and "0.5" (for example). How do I construct the output expression for "B"? I was thinking something like B = min(A, 0.5).

Have you considered using a conditional expression to define your variable B? For example:

B is a new design variable dependent on the value of A. Hence define variable B as:

if( (VAL("A") < 0.5) then VAL("A") else 0.5)

yxie, sadly Shawn's answer won't work because a) you're talking about an output expression, and b) he uses a function VAL() that doesn't exist (I assume he meant VAR()).

Anyway, the way to do this would indeed to be have an output with an expression min(A 0.5) - the min function does support waveform objects as well as numbers, so this should work fine (at least it does in current versions; I just tested it; I'm not sure which IC sub-version you're using since you didn't say).

Yeah, thanks, Andrew, it works with this subversion I am now working with IC6.1.8-64b.500.25. Also, thank Shawn - yes, I did try that as well; somehow the subversion I was working with then didn't seem to work. Anyhow, the min/max function allows me set the upper and lower limit to a trim code which also a design variable, that based on a measurement on simulation result of previous run.
