New ContributorCyclone-V SCFIFO with M10K/MLAB memory - adding ECC
Hi,
I am working with a Cyclone-V 5CSXFC6C6U2317 FPGA and using the MegaWizard's IP FIFO SCFIFO in it. The SCFIFO is for custom logic and is outside of the HPS/ARM/Nios sub-system. My Quartus is 23.1 Prime Standard Edition. From the "FIFO IP User Guide for Quartus® Prime Design Suite: 25.1.1" it looks like I can enable (hard, memory-build in) ECC protection only for Arria 10 devices with M20K memory. My Cyclone-V has M10K memory (and Auto and MLAB memory) . It should be possible for me to add a soft-ECC module in the fabric, either inside the SCFIFO wrapper (from MegaWizard), or outside the SCFIFO wrapper.
Has anyone done (or seen in Altera's Github) such a soft-ECC module ( for example using a Hamming SEC-DED (24,16) code or similar) ?

I will check if we have similar soft ECC module for Cyclone V,
But to answer your question, ECC only support in M20k. https://community.altera.com/kb/knowledge-base/why-does-the-fifo-fpga-ip-gui-not-produce-any-error-message-when-the-enable-erro/342532

The closes i can find is https://github.com/diogocgi/SEC-with-Binary-Hamming-Codes, does it suite your case?

Do you have update for the above?

Since there are no update for the above, we shall close this thread.
nilievI have found the ALTECC soft-ECC IP in the IP-Catalog for Cyclone-V. It should work with M10K memory.
