Configurable termination circuits for use with programmable logic devices are disclosed. In one implementation, the termination circuit may include one or more components to couple unused inputs of one or more configurable logic blocks to a fixed voltage. In another implementation, the termination circuit may include one or more components to couple unused inputs of one or more configurable logic blocks to an output of the one or more configurable logic blocks. In some implementations, the programmable logic device may include a platform management controller to configure the termination circuits based on configuration data.
