Constants

Name Type Value Description
PACKETIZER_AXIS_CONFIG_C AxiStreamConfigType ( TSTRB_EN_C => false,
TDATA_BYTES_C => 8,
TDEST_BITS_C => 8,
TID_BITS_C => 8,
TKEEP_MODE_C => TKEEP_COMP_C,
TUSER_BITS_C => 8,
TUSER_MODE_C => TUSER_FIRST_LAST_C)		 This should really go in a AxiStreamPacketizerPkg
CONV_AXIS_CONFIG_C AxiStreamConfigType ite(BYPASS_CHUNKER_G,
RSSI_AXIS_CONFIG_C,
PACKETIZER_AXIS_CONFIG_C)		 If bypassing chunker, convert directly to RSSI AXIS config else use Packetizer AXIS format. Packetizer will then convert to RSSI config.
MAX_SEGS_BITS_C positive bitSize(MAX_SEG_SIZE_G)
