Enumeration Type Documentation

enum bert_adr

addresses of bert internal registers
used by SIM::bert.set_adr() for defining target register of SIM::bert.get_state()

Enumerator
BERT_ADR_LSRX	X[0:N] LSR.
BERT_ADR_LSRY	Y[0:N] LSR.
BERT_ADR_PRBS	PRBS[0:n] LFSR, size determined by PRBS index or poly, n<=N.

enum bert_fsm_state

states of bert internal FSM - auto transitions in SIM::bert::process()
transitions are determined by threshold settings [T0,T1,T2]
metrics is sum(xor(X,Y)) where X[0:N-1] is input fed LSR, Y[0:N-1] is PRBS fed LSR
N should be greater or equal with PRBS size due setting state of PRBS LFSR in RELOAD state

Enumerator
BERT_FSM_RESET	static idle state - no auto transition
BERT_FSM_RELOAD	(after N bits shifted in X and PRBS<=X)->PRESET
BERT_FSM_PRESET	after N bits shifted (metrics > T2)->RELOD, (T1 < metrics < T2)->nSYNC, (metrics<T0)->SYNC
BERT_FSM_nSYNC	(metrics <=T0)->SYNC, (metrics <=T0)->RELOD
BERT_FSM_SYNC	(metrics >T1)->nSYNC
