摘要： After a delay lock loop synchronizes a reference clock signal with a skewed clock signal, a digital phase shifter can be used to shift the skewed clock signal by a small amount with respect to the reference clock signal. The tap/trim settings of a delay line in the main path of the delay lock loop can be transmitted to the digital phase shifter, thereby informing the digital phase shifter of the period of the reference clock signal. In response, the digital phase shifter provides a phase control signal that introduces a delay, which is referenced to the period of the reference clock signal, to either the reference clock signal or the skew clock signal. The phase control signal is proportional to a predetermined fraction of the period of the reference clock signal. The digital phase shifter can be controlled to operate in several modes. In a first fixed mode, the digital phase shifter introduces delay to the skew clock signal. In a second fixed mode, the digital phase shifter introduces delay to the reference clock signal. In a first variable mode, the digital phase shifter can cause the reference clock signal to lead or lag the skew clock signal by controlling the delay of the reference clock signal. In a second variable mode, the digital phase shifter can cause the reference clock signal to lead or lag the skew clock signal by controlling the delay of the skew clock signal.

摘要： A multi-product integrated circuit die includes at least two different portions, of which at least one portion can be deliberately rendered non-operational in some manner (e.g., non-functional, inaccessible, and/or non-programmable) within the package. A selection code storage circuit stores a product selection code. A first value of the product selection code selects the option where both the first and second portions of the first die are operational. A second value of the product selection code selects the option where only the first portion of the first die is operational. The selection code storage circuit can include non-volatile memory or a fuse structure, or the product selection code can be configured as a package bonding option. The product selection code can also enable boundary scan for the operational portion of the die, and omit from the boundary scan chain any portions of the die that are deliberately rendered non-operational.

According to a third aspect of the invention, the reference input of an I/O is configurably connected to any of two or more input reference voltage lines. According to another aspect of the invention, a single input reference voltage and/or a single output voltage supply is applied to each IOB, with the IOBs grouped into sets.

摘要： An integrated circuit die (e.g., a programmable logic device (PLD) die) is manufactured that has the capability of being configured as at least two differently-sized family members. The IC die is tested prior to packaging. If a first portion of the IC die is fully functional, but a second portion includes a localized defect, then the IC die is packaged with a product selection code that configures the IC die to operate as only the first portion of the die. The second portion of the die is deliberately rendered non-operational. Therefore, the IC die can still be sold as a fully functional packaged IC.

摘要： A method of providing a family of integrated circuits (ICs) includes applying a first product selection code (PSC) to a first IC die, applying a second PSC to a second IC die, and providing a third packaged IC die. The first IC die includes first and second portions, both of which are operational based on the first PSC. The second IC die is a duplicate of the first die, but the second portion is rendered non-operational by the second PSC. The third IC die is substantially similar to the first portion of the first die. The second and third packages can be the same and the packaged dies can be interchangeable in a system. When the dies are programmable logic device (PLD) dies, the second and third dies use the same configuration bit stream, which may be smaller than the configuration bit stream for the first IC die.
