This test injects a fault into different MuBi encoded signals within the prim_ram_1p_scr and prim_ram_1p_adv and checks whether a fatal alert is triggered. I have excluded the addr_match signal from FI as its encoding is not directly checked. If the signal was a MuBi True, a fault into it is treated by the mubi4_and_hi as a False. If the signal was a MuBi False, a fault into it is treated by the mubi4_and_hi also as a False. Hence, no address collision occurs and the holding register is not returned. This PR is based on lowRISC#2182 and closes lowRISC#2173. Signed-off-by: Pascal Nasahl <[email protected]>
