Title: Configurable ICs that conditionally transition through configuration data sets

Abstract: Some embodiments provide a method of operating a configurable circuit. The method performs a first operation by the configurable circuit based on a first configuration data set. When a user-design signal has a value from a set of values, the method performs a second operation based on a second configuration data set, after the first operation. When the user-design signal does not have a value from said set of values, the method performs a third operation based on a third configuration data set, after the first operation. Some embodiments provide a reconfigurable IC that includes a set of reconfigurable circuits and sets of associated configuration storage elements that store configuration data sets. At least one reconfigurable circuit receives a first sub-set of its configuration data when a user-design signal has a first value and receives a second sub-set of its configuration data when the user-design signal has a second value.
