Port
R
Where <Sln> is a meaningful name or acronym for the slave output. An additional
requirement on <Sln> is that it must not contain the string, “OPB” (upper or lower case or
mixed case), so that slave outputs will not be confused with bus outputs.
tmr_xferAck
uart_xferAck
intc_xferAck
OPB Slave Inputs
For interconnection to the OPB, all slaves must provide the following inputs:
<
nOPB>_ABus
<nOPB>_BE
<nOPB>_DBus
<nOPB>_RNW
<nOPB>_select
<nOPB>_seqAddr
Where <nOPB> is a meaningful name or acronym for the slave input. An additional
requirement on <nOPB> is that the last three characters must contain the string, “OPB”
(upper or lower case or mixed case).
OPB_DBus
iOPB_DBus
bus1_OPB_DBus
Master PLB Ports
Naming conventions should be followed for that part of the identifier following the last
underscore in the name.
PLB Master Outputs
For interconnection to the PLB, all masters must provide the following outputs:
<Mn>_ABus
<Mn>_BE
<Mn>_RNW
<Mn>_abort
<Mn
>_busLock
<Mn
>_compress
<Mn
>_guarded
<Mn>_lockErr
<Mn>_MSize
<Mn>_ordered
<Mn>_priority
<Mn>_rdBurst
<Mn>_request
<Mn>_size
<Mn>_type
<Mn>_wrBurst
<Mn>_wrDBus
Where <Mn> is a meaningful name or acronym for the master output. An additional
requirement on <Mn> is that it must not contain the string, “PLB” (upper or lower case or
mixed case), so that master outputs are not confused with bus outputs.
