3.5.1.18.4 ECC Support Status

(Ask a Question)

The following is a summary of supported features and limitations in the current release:

If you use an ECC memory, SmartHLS™ will always instantiate an LSRAM block. uSRAM blocks with ECC (only available for RTG4™ devices) are currently not supported (Planned for future releases).
Byte-write enable memories with ECC (only available for PolarFire® devices) are not supported (Planned for future releases).
Only non-pipelined ECC mode is supported (Pipelined ECC is planned for future releases).
Only local ECC memories instantiated by SmartHLS are supported (External ECC memories are planned for future releases).
If memory is partitioned into individual elements (registers), ECC logic will be optimized away.
ECC with memory controllers are not supported in current release (Planned for future releases).
Memory initialization for RTG4™ devices need to be configured manually. For more details, see AN4892: RTG4 SRAM Initialization After Powerup Using μPROM Application Note.
