摘要： A set of tools is provided herein that produces useful, proven, and correct integrated semiconductor chips. Having as input either a customer's requirements for a chip, or a design specification for a partially manufactured semiconductor chip, the tools generate the RTL for control plane interconnect; memory composition, test, and manufacture; embedded logic analysis, trace interconnection, and utilization of spare resources on the chip; I/O qualification, JTAG, boundary scan, and SSO analysis; testable clock generation, control, and distribution; interconnection of all of the shared logic in a testable manner from a transistor fabric and/or configurable blocks in the slice. The input customer requirements are first conditioned by RTL analysis tools to quickly implement its logic. The slice definition and the RTL shell provides the correct logic for a set of logic interfaces for the design specification to connect. The tools share a common database so that logical interactions do not require multiple entries. The designs are qualified, tested, and verified by other tools. The tools further optimize the placement and timing of the blocks on the chip with respect to each other and with respect to placement on a board. The suite may be run as batch processes or can be driven interactively through a common graphical user interface. The tools also have an iterative mode and a global mode. In the iterative mode, one or more of the selected tools can generate the blocks or modify a design incrementally and then look at the consequences of the addition, or change. In the global mode, the semiconductor product is designed all at once in a batch process as above and then optimized altogether. This suite of generation tools generates design views including a qualified netlist for a foundry to manufacture.

摘要： A delay line calibration circuit and method are provided in which a programmable master delay line drives a delay clock and has a propagation delay that is a function of a delay setting. A delay counter is clocked by the delay clock and has a delay count. A reference counter is clocked by a reference clock and has a reference count. A control circuit controls the delay and reference counters, compares a representation of the delay count to a representation of the reference count and responsively generates a modified value for the delay setting to reduce a difference between the representations of delay count and the reference count.

摘要： A converged network adapter in sleep mode can allow a management entity to access and alter configuration of the network adapter over the network. Configuration data such as configuration parameters, firmware, and other data related to the network adapter can be stored in a memory, which can be coupled to a portion of the adapter that receives power during sleep mode. The management entity can send configuration messages to the adapter, which messages can include commands or instructions to read or write contents of the memory. The messages can include values of the configuration parameters to be altered, firmware code, etc. The management entity can also send configuration messages to a baseboard management controller (BMC) coupled to the adapter for message validation. The adapter and the BMC can send results of memory operations back to the management entity in response messages.
