4.4.3. Metric Expressions

The metric for an optimization is an expression which can be combination of constants, variables and built-in functions. Optimizations will always attempt to drive the metric value to the Metric > Target(GHz) parameter in the algorithm.

The most common function found in metric expressions is cellvalue. The arguments for the cellvalue function are measurement label, row index, column index and default value. If the cell is not found in the measurement, the default value will be used instead.

Is is common to assign variables to expressions using cellvalue functions and then use those variables in the metric itself.
