RiseT = riseTime(VT("/OUT") 0 nil vdd t 10 90 nil "time" nil nil )

*Error* eval: unbound variable - vdd
*Error* load: error while loading file - "script.ocn"

pls help!!
 

unbound variable in ocean script

May be you have several items/devices called "vdd" ?
E.g. a pin called "vdd" and/or a vdc source called "vdd" and your variable "vdd". In this case ocean resp. the simulator cannot differentiate between those.
So you should rename the others.

I think the parameter should be in (double) quotes: "vdd" .
