摘要： A bitstream having a plurality of data sets is provided to an integrated circuit device such as an FPGA having test circuitry capable of routing data to the device's internal resources, with each data set including configuration information and a trigger signal. Successive data sets of the bitstream are sequentially processed by the test circuitry in response to the trigger signals to sequentially initialize the device's resources to various states. For some embodiments, each data set includes configuration data to configure one or more configurable elements of the device to implement a desired design and includes soft data for use by a processor embedded within the device. For one embodiment, control logic is provided to selectively wait for a predetermined time period before processing a next data set.

摘要： A software architecture for facilitating communications between a computer or workstation and a programming apparatus used to program a PLD by minimizing the number of two-way communications on a standard download cable (e.g., RS232, USB) connected between the computer and the programming apparatus. A first component used to encode programming instructions and configuration data to form a first transmission stream that is transmitted to the programming apparatus in a single, long burst. The programming apparatus includes a second component of the software architecture that interprets the first transmission stream and programs the PLD using, for example, Boundary-Scan signals that are generated in response to the programming instructions and configuration data. A buffer memory stores data shifted out of the PLD during the programming operation, which is transmitted to the computer in a single, long burst after the first transmission stream is completed.

摘要： A method for programming a series of in-system programmable devices that uses Boundary-Scan techniques to read device identification codes from each device of a system, and to automatically generate a board/device information file including a record for each device arranged in the order in which the devices are chained in the system. The device identification codes are then used to automatically retrieve device specifications from a central database. When no identification code is provided from the device, or the database fails to include specifications for a particular device, the user is prompted to enter minimum information or specifications necessary to carry out communications with the device. After device specifications are entered for each device, the user is prompted to enter configuration data, which is automatically matched to its associated device, and compared for consistency with the device specifications. After verifying the configuration data, programming is performed using the configuration data.

摘要： A method for concurrently programming a series of in-system devices by grouping the devices into sequentially-programmed groups, wherein a best possible grouping of devices is determined that achieves a minimum total configuration time. When a system includes multiple devices, it is sometimes more efficient (i.e., requires less total configuration time) to program the devices in two or more groups, as compared to programming all of the devices at the same time (i.e., as a single group). The method utilizes device information to identify an optimal or best grouping by comparing the total configuration times of several possible groupings, and selecting the grouping having the lowest total configuration time. Once a best grouping is determined, programming is performed by selecting a first group from the grouping and programming the first group while bypassing devices all other groups. Once the first group is programmed, a next group is programmed, and so on.
摘要翻译：一种用于通过将设备分组为顺序编程的组来同时编程一系列系统内设备的方法，其中确定实现最小总配置时间的最佳可能的设备分组。当系统包括多个设备时，与同时编程所有设备（即，作为单个组）相比，有时更有效（即，需要更少的总配置时间）来编程两个或更多个组中的设备）。该方法利用设备信息通过比较几个可能的分组的总配置时间以及选择具有最低总配置时间的分组来识别最佳或最佳分组。一旦确定了最佳分组，则通过从分组中选择第一组并且在绕过所有其他组的设备的同时编程第一组来执行编程。一旦第一组被编程，下一个组被编程，依此类推。

摘要： A method of detecting an error when loading a programmable integrated circuit (IC) can include detecting a predetermined bit pattern indicating a start of a bitstream within the programmable IC, starting a timer within the programmable IC responsive to detecting the predetermined bit pattern, and determining whether a bitstream load complete condition has occurred prior to expiration of the timer. When the timer expires prior to an occurrence of the bitstream load complete condition, at least one recovery action can be implemented.
