R
Master OPB Ports
Naming conventions should be followed for that part of the identifier following the last
underscore in the name.
OPB Master Outputs
For interconnection to the OPB, all masters must provide the following outputs:
<Mn>_ABus
<Mn>_BE
<Mn
>_busLock
<Mn>_DBus
<Mn>_request
<Mn>_RNW
<Mn>_select
<Mn>_seqAddr
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, “OPB” (upper or lower case or
mixed case), so that master outputs are not confused with bus outputs.
iM_request
bridge_request
o2ob_request
OPB Master Inputs
For interconnection to the OPB, all masters must provide the following inputs:
<
nOPB>_DBus
<nOPB>_errAck
<nOPB>_MGrant
<nOPB>_retry
<nOPB>_timeout
<nOPB>_xferAck
Where <nOPB> is a meaningful name or acronym for the master input. An additional
requirement on <nOPB> is that the last three characters must contain the string, “OPB”
(upper or lower case or mixed case).
iOPB_DBus
OPB_DBus
bus1_OPB_DBus
Slave OPB Ports
Naming conventions should be followed for that part of the identifier following the last
underscore in the name.
OPB Slave Outputs
For interconnection to the OPB, all slaves must provide the following outputs:
<Sln>_DBus
<Sln>_errAck
<Sln>_retry
<Sln>_toutSup
<Sln>_xferAck
