sec_ded

Component for Single Error Correction and Double Error Detection (SEC-DED) in LPDDR4.

SecDed

Bases: Base

Component for Single Error Correction and Double Error Detection (SEC-DED).

This module manages diagnostic coverage for multiple fault types and handles transformations between failure modes (e.g., TBE -> MBE).
