Description
strap_en
logic
uni
rcv
1
The strap enable signal tells gpio to take a snapshot of the input pins. The behaviour of this signal after that event will have no effect.
sampled_straps
gpio_pkg::gpio_straps
uni
req
1
This vector contains the sampled strap values.
racl_policies
top_racl_pkg::racl_policy_vec
uni
rcv
1
Incoming RACL policy vector from a racl_ctrl instance. The policy selection vector (parameter) selects the policy for each register.
racl_error
top_racl_pkg::racl_error_log
uni
req
1
RACL error log information of this module.

Interrupt Name
Type
Description
gpio[31:0]
Event
raised if any of GPIO pin detects configured interrupt mode
Alert Name
Description
fatal_fault
This fatal alert is triggered when a fatal TL-UL bus integrity fault is detected.
Countermeasure ID
Description
GPIO.BUS.INTEGRITY
End-to-end bus integrity scheme.
