HWA module consists of Parity and FSM Lockstep Diagnostics

Features Supported

HWA supports Diagnostic check for Parity Errors on HWA Data memoriers and window ram on both HWA DMA0 and HWA DMA1.

• Parity Errors : This incluedes parity error injection on both HWA DMA0 and DMA1.
• FSM LOCKstep Errors : This incluedes fsm lockstep error injection HWA.

Example Usage

The following shows an example of SDL HWA API usage by the application for Error Injection Tests.

Include the below file to access the APIs
