Soft Error Mitigation Controller v4.0: SSI makedata.tcl may return an error when targetting XC7VH580T


This issue can arise when using correction by replace mode or with error classification using external SPI memory.

When generating the external memory file and executing makedata.tcl, it may fail with an error.


This issue is only applicable to XC7VH580T and is currently being investigated. 

The message below might be encountered when executing the .tcl:

can't read "ebc_exists": no such variable"
