Hi Salim,

 

you can do if conditions like this:

 

“GE (input1, input2) * 333 + LT(input1, input2) * 666“

 

Explanation:

 

GE… ‘greater equal’

LT… ‘less than’

 

In the first term GE(…) compares the two inputs and returns ‘1’ if condition is true or ‘0’ if not - Second term works the same way…

So if input1 >= input2 the function above returns 333, if not the result is 666.

 

Kind regards,

Markus.

Hi all,

 

I’ve a simple question related to the use of the equation editor in simulation studio. Can we use a condition (if) to define an output from an equation editor ? What is the syntax ? (example: if Input = x then Output = y)

 

Best regards
