Name Type Value Description
LIST_OF_ALERTS string {
"fatal_error"}		 parameters
uint uint 1
KDI_DATA_SIZE int 1 + otp_ctrl_pkg::SramKeyWidth + otp_ctrl_pkg::SramNonceWidth Number of bits in the otp_ctrl_pkg::sram_otp_key_rsp_t struct: 1 bit for valid, SramKeyWidth bits for the key, SramNonceWidth bits for the nonce.
KDI_PROPAGATION_CYCLES int 2 after a KDI transaction is completed, it needs 2 cycles in the SRAM clock domain to be properly synchronized and propagated through the DUT
LC_ESCALATION_PROPAGATION_CYCLES int 3 a LC escalation request needs 3 cycles to be fully propagated through the DUT
