C_LMB_AWIDTH
The C_LMB_AWIDTH parameter defines the LMB address width in bits. This parameter is
automatically populated by the EDK tools.
Format
PARAMETER C_LMB_AWIDTH = <num>, DT=integer
Where <num> is an integer value.
C_LMB_DWIDTH
The C_LMB_DWIDTH parameter defines the LMB data width in bits. This parameter is
automatically populated by the EDK tools.
Format
PARAMETER C_LMB_DWIDTH = <num>, DT=integer
Where <num> is an integer value.
C_LMB_MASK
The C_LMB_MASK parameter defines the LMB decode mask. This parameter is
automatically populated by the EDK tools.
The address mask indicates which bits are used in the LMB decode to decode that a valid
address is present on the LMB. Any bits that are set to 1 in the mask indicate that the
address bit in that position is used to decode a valid LMD access. All other address bits are
considered don’t cares for the purpose of decoding LMB accesses. The EDK tools may limit
the users choice for the address mask: the most restrictive case is that only a single bit may
be set in the mask.
Format
PARAMETER C_LMB_MASK = <hex>, DT=std_logic_vector(0 to 31)
Where <hex> is a hex value.
C_LMB_NUM_SLAVES
The C_LMB_NUM_SLAVES parameter defines the number of LMB slaves on the bus. This
parameter is automatically populated by the EDK tools.
Format
PARAMETER C_LMB_NUM_SLAVES = <num>, DT=integer
Where <num> is an integer value.
C_OPB_AWIDTH
The C_OPB_AWIDTH parameter defines the OPB address width in bits. This parameter is
automatically populated by the EDK tools.
Format
PARAMETER C_OPB_AWIDTH = <num>, DT=integer
Where <num> is an integer value.
