I am using spectre with signalstorm to characterize a cell library. The kit provides a process parameter file that uses arithmetic and trig functions for parameter expressions (sqrt, exp). I'd like to know what libraries contain these arith and trig function definitions that spectre would need to call in order for the parameter expressions to pass.

In other words, spectre is terminating because it can't find definitions for the math functions being used in the parameter files.

Thanks
