Before Fault Injection:
wire DONE_OBUF_4985;
X_SFF #(
  .INIT (1b0))
DONE_3 (
  .CLK(CLK_BUFGP),
  .I(count _DONE_Select_14_o),
  .SRST(RST_START_OR_1_o),
  .O(DONE_OBUF_4985),
  .CE(VCC),
  .SET(GND),
  .RST(GND),
  .SSET(GND)
);
X_LUT2 #(
  .INIT (4h8))
Mmux_DOUT1111 (
  .ADR0(DONE_OBUF_4985),
  .ADR1(aes_dout ),
  .O(DOUT_84_OBUF_5035)
);
After Fault Injection:
wire DONE_OBUF_4985;
wire DONE_OBUF_4985_tmp;
assign DONE_OBUF_4985_tmp=1 ; //Stuck-At 1’  fault
X_SFF #(
  .INIT (1b0))

  .I(count _DONE_Select_14_o),
  .SRST(RST_START_OR_1_o),
  .O(DONE_OBUF_4985),
  .CE(VCC),
  .SET(GND),
  .RST(GND),
  .SSET(GND)
);
X_LUT2 #(

Mmux_DOUT1111 (
  .ADR0(DONE_OBUF_4985_tmp ),
