An integrated circuit includes a programmable logic circuit and freeze circuitry coupled to receive a freeze signal and a control signal. The integrated circuit also includes a logic circuit coupled to receive an output signal of the programmable logic circuit. The logic circuit is also coupled to receive an output signal of the freeze circuitry. The freeze circuitry causes an output signal of the logic circuit to be in a predefined logic state in response to the freeze signal being asserted during power-up of the integrated circuit. The integrated circuit also includes clear circuitry that asserts the control signal in response to a clear signal being asserted after the power-up of the integrated circuit. The freeze circuitry causes the output signal of the logic circuit to be in the predefined logic state in response to the control signal being asserted.

Freeze and clear logic circuits and methods for integrated circuits

An integrated circuit includes a logic block configured to perform multiplication operations. The logic block includes a plurality of lookup tables configured to receive a plurality of inputs and generate a first plurality of outputs. Additionally, the logic block includes adding circuitry configured to receive the first plurality of outputs and generate a second plurality of outputs. Furthermore, the logic block includes circuitry configured to receive a portion of the plurality of inputs, determine one or more partial products, and generate a third plurality of outputs.
