Generics

Generic name	Type	Value	Description
AES192Enable	bit	1	Can be 0 (disable), or 1 (enable).
Masking	bit	1	Can be 0 (no masking), or
SBoxImpl	sbox_impl_e	SBoxImplDom	See aes_pkg.sv
SecStartTriggerDelay	int unsigned	0	Manual start trigger delay, useful for
SecAllowForcingMasks	bit	0	Allow forcing masks to 0 using
SecSkipPRNGReseeding	bit	0	The current SCA setup doesn't provide enough
NumAlerts	logic [NumAlerts-1:0]	undefined	resources to implement the infrastucture required for PRNG reseeding (CSRNG, EDN). To enable SCA resistance evaluations, we need to skip reseeding requests. Useful for SCA only.
