Abstract
A method and hardware design is disclosed for allowing the bring-up of a large scale system of interfaces that need to undergo a sequence of calibration steps. The method involves the use of a flexible broadcast scheme whereby groups of interfaces within a chip are assigned to groups to which commands can be broadcast. The scheme allows for the maximum amount of flexibility, allowing interfaces to be assigned to multiple groups which can overlap and be subsets of one another, and still allows for groups to be excluded from broadcast commands and be access individually. A method is also disclosed for using a chip-global status summary that can be accessed as any other register on the chip and can report calibration results for an entire chip with only one command. According to the invention a service utilizing the method embodied with code for implementing the method can now be provided.
