Soft Error Mitigation Controller- Is the MCS file used for error correction by replace the same as the configuration bitstream?

Description

When error correction by replace is in use, an image of the configuration data is programmed to SPI memory.

Is this MCS data the same as the FPGA bitstream configuration data? Is it necessary to update the correction by replace data if the configuration bitstream is updated?

Solution

The two files are very different. A bitstream is a packetized sequence of commands and data.The correction by replace data is not packetized, it is a flat dump of configuration frames.The two are related so if a new bitstream is created, you must change the correction by replace MCS file on the SPI flash.
