Bitstream readback
Web* readback FPGA configuration register or memory data. The application above the * driver should take care of creating the data that needs to be downloaded to * the FPGA so that the bitstream can be readback. * This driver also does not support the reading of the internal registers of the * PCAP. The driver has no knowledge of the PCAP internals. * WebJul 16, 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.
