Abstract: A method for correlating a structural parameter of a plurality of gratings acquires images from a plurality of gratings, which have different structural parameters. A focus metrics algorithm is then performed to find the off-focus offset of the orders of each grating from the intensity variation of these images, and the variation ratio of the off-focus offset to the order for each grating is calculated later. Consequently, the structural parameters of these gratings can be correlated based on the variation ratio of the off-focus offset to the order. The present method acquires images from an unknown grating at different off-focus offsets, and performs a focus metrics algorithm to find the off-focus offset of the orders of the unknown grating. The variation ratio is calculated and the structural parameter of the unknown grating is determined based on the variation ratio.

Abstract: A clock enable control circuit for controlling flip flops on a programmable logic device. The clock enable control circuit either passes an original data signal to the input terminal of a flip flop, or feeds back an output signal from the output terminal to the input terminal of the flip flop in response to a clock enable control signal. The clock enable control signal is selected from one of a set control signal and a reset control signal that are otherwise provided on the programmable logic device to selectively control set and reset functions of the flip flop. In one embodiment, the set and reset control signals are generated as product-term signals that are programmably routed by a product-term allocator circuit to a macrocell including the flip flop and the clock enable control circuit.

Abstract: An overridable data protection mechanism for unlocking/locking a PLD includes a data protect override key register, an input key register, and a comparator. After the user inputs an access code to the input key register, the software program sends an enabling signal to the comparator which in turn compares the bits stored in the data protect override key register and the bits in the input key register. If the bits in the two registers are identical, then the comparator outputs a disable data protect signal, thereby allowing the user to modify the configuration data in that PLD. After an incremented version control number and the new configuration data are downloaded to the PLD, the program sends a disabling signal to the comparator, thereby preventing further modification to the configuration data on that PLD.
