Description of the Expression Editor functions
Declared operands and constants from Tools menu or changing a submodel parameter
When you open the Expression Editor from the Tools menu, or when you change a submodel parameter, the Declared operands and constants tab displays any global parameters and any constants for the circuit:
Global parameters
If GP1, GP2 and GP3 are declared as global parameters for the model, they will also appear in the Declared operands list:
The following are valid calculated items:
GP1+GP2
GP1-GP2
12.3
(GP1+GP2)/GP3
sin(GP1)
GP1*pi
GP1**2
GP2^2
max(GP1,GP2/GP3,abs(GP1))
Simcenter Amesim Run will first check your expression. If it finds it is acceptable, it will enter the expression as a value of a parameter if you started the Expression Editor when changing a parameter.
The maximum size for an expression is 255 characters.
Fundamental constants
The value of Pi is available.
