Integrity checking of configuration data of programmable device

摘要

Methods and a system for operating a programmable device are disclosed. In one embodiment, a method includes accessing a master summary data and loading an original configuration data to configuration registers of the programmable device. The method further includes generating a current summary data by performing a summary operation of a current configuration data of the configuration registers of the programmable device, comparing the current summary data with the master summary data, and performing an exception action if the current summary data does not match with the master summary data.

主权项

1. A method of operating a programmable device, the method comprising:
loading an original configuration data to configuration registers of the programmable device, wherein the original configuration data comprises data to establish a plurality of functional blocks in the programmable device to perform user-defined logic functions; accessing first master redundancy check (RC) data corresponding to an RC operation of the original configuration; accessing second master RC data corresponding to an RC operation of the original configuration; comparing the first master RC data with the second master RC data; performing a first exception action if the second master RC data does not match with the first master RC data; generating current RC data by performing a RC operation of a current configuration data of the configuration registers of the programmable device; comparing the current RC data with the first master RC data; and performing a second exception action if the current RC data does not match with the first master RC data.
