摘要： Methods, computer program products, and systems are disclosed associated with calculating a routability metric for a second IC design using inputs from the compilation to a first IC design. The first and second IC designs are alternative implementation options for a user circuit design, such as FPGA and structured ASIC options. Information about user design demands on routing resources of one IC design are considered along with information about the projected supply of routing resources in another IC design, to produce a routing metric. The routing metric may be mapped to a degree of difficulty indicator, and either may be used to condition a compile of the user circuit to the second IC design or be used in other ways.

摘要： A circuit includes a receiver channel and a built-in self-test circuit. The receiver channel has a serializer and a deserializer. The built-in self-test circuit generates test signals that are transmitted in parallel to the serializer during a test of the receiver channel. The serializer converts the test signals into serial test signals. The deserializer converts the serial test signals into parallel test signals that are transmitted to the built-in self-test circuit.

摘要： Techniques for combining volatile and non-volatile programmable logic into one integrated circuit (IC) are provided. An IC is segregated into two portions. A first block of programmable logic is configured by bits stored in on-chip non-volatile memory. A second block of programmable logic is configured by bits stored in off-chip memory. The function of IO banks on the IC is multiplexed between the two logic blocks of the IC. The programmable logic in the first block can be configured and fully functional in a fraction of the time that the programmable logic in the second block can be configured. The programmable logic in the first block can configure fast enough and have enough independence to assist in the configuration of the second block. The non-volatile memory can also provide security features to a user design, such as encryption.

摘要： A circuit includes a clock routing network. The clock routing network includes first and second clock paths. The first clock path routes a first clock signal to sub-circuits in the circuit. The first clock path has first buffers that buffer the first clock signal at the sub-circuits and first conductors in a first conductive layer of the circuit that transmit the first clock signal. The second clock path routes a second clock signal to the sub-circuits. The second clock path has second buffers that buffer the second clock signal at the sub-circuits, second conductors in the first conductive layer that transmit the second clock signal, and third conductors in a second conductive layer of the circuit. The second clock signal is routed through the third conductors at overlaps between the first clock path and the second clock path.
