If you are looking to change a number of IOCells in an IBISDevice that is already in a dml file, then you can use the Device Model Editor to assign a IOCell to a whole group of pins easily. From the model assign form (assuming you have already assigned the model) select the device you want to change, edit it. This will open the IBIS Device Model Editor. Click on the Assign Signal Pins tab, then you can can use the filters to select by netname, IOCell assigned, pin #...
Once filtered, select them all to move to the lower pane of the form, then browse to find the IOCell you want to assign, click the Assign button, then deselect them all to move back to the top pane. Save the model.
If you open the form from the library as opposed to the model assign, it works the same, except you will not be able to use the netname as a filter, since it isn't known at the lib level.
