UDS Get Seed

Block to read the 32-bit seed that was previously set with the 'UDS Set Seed' block.

Description

The 'UDS Get Seed' block reads the 32-bit seed that was previously set with the 'UDS Set Seed' block. In the seed/key sequence to unlock a resource, the key is typically derived from the seed using an application specific computation. In this case, the 'UDS Get Seed' is typically used in the function-call subsystem connected to the output of the 'UDS Verify Key Event' block to verify that the key, received from the UDS tester, is actually valid.

Parameters
Sample time
Sample time of the block. The Sample time (in seconds) defines the rate at which the block is visited by the real-time scheduler of the target. The value of the Sample time has to be an integer multiple of the base sample time of the model. Set it to -1 (inherited) when used inside a function-call subsystem.
Outputs
Seed
32-bit value of the seed that was previously set with the 'UDS Set Seed' block.
