Bitstream readback
WebJun 26, 2024 · A CRC check value is calculated and compared with that computed from the original bitstream to validate the integrity of the current configuration. Some bits can change during normal user operation, e.g. distributed RAM or BRAM, and the CRC function can mask these variable locations. There are two readback modes: verify and capture. WebTo verify the readback data stream, compare it to the RBD golden readback file and masking readback bits with the MSD file. This approach is simple because there is a 1:1 correspondence between the start of the readback data stream and the start of the RBD and MSD files, making the task of aligning readback, mask, and expected data easier.
