    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 memory controller circuit arrangement and method utilize a tuning circuit that dynamically controls the timing of memory control operations, rather than simply relying on fixed timing parameters that are either hardwired or initialized upon startup of a memory controller. Dynamic control over the timing of memory control operations typically incorporates memory test control logic that verifies whether or not a memory storage device will reliably operate using the dynamically-selected values of given timing parameters. Then, based upon the results of such testing, such dynamically-selected values are selectively updated and retested until optimum values are found. The dynamically-selected values may be used to set one or more programmable registers, each of which may in turn be used to control the operation of a programmable delay counter that enables a state transition in a state machine logic circuit to initiate performance of a memory control operation by the logic circuit. Dynamic tuning may also utilize a unique binary search engine circuit arrangement that updates one of two registers with an average of the current values stored in such registers based upon the result of a test performed using that average value. By selectively updating such registers, a fast convergence to an optimum value occurs with minimal circuitry.

    摘要: A memory controller circuit arrangement and method utilize a tuning circuit that controls the timing of memory control operations via one or more programmable delay counters. Each counter is programmed to cycle a selected number of clock cycles to delay performance of a memory control operation to meet a predetermined timing parameter for a memory storage device coupled to the controller. Through the use of programmable delay counters, a variety of memory storage devices having varying timing parameters may be supported by the same memory controller design. Moreover, the use of programmable delay counters permit a single path of execution in a memory controller state machine to support any number of timing parameter variations for a particular timing characteristic, as well as multiple timing characteristics.
