Description
No. The current BSDL file does not need to be modified. You can change the disable result element from "X" to "PULL1" for any cells that are connected to IOs that have the weak pull-up resistor enabled. There is no way to modify the file to emulate the bus hold feature.
If the files were written with "PULL1", instead of "X", then you have to modify the file for all IOs that didn't use the pull-up resistor. The modifications are optional by making the disable result element "X".
