Product Specification
When these match units are enabled, all slaves or masters are enabled. You cannot individually enable a particular
master.
The match units 7, 8, and 9 are slave side signals for BUSY, READ, and WRITE error controls going to the mas-
ter. These units are broken out individually because this bus has one signal for each master on each slave. Conse-
quently, you can have up to 256 signals on each one of these match units (if PLB goes to a 16 slave, 16 master
solution).
The arbiter status signals can be monitored using match unit 10. The signals probed by this match unit can help
identify the order of the PLB master transactions that are being sorted on the bus.
ChipScope PLB46 IBA Parameters
To create a ChipScope PLB46 IBA uniquely tailored for your system and to optimize performance, specific fea-
tures can be parameterized on the PLB IBA. Table 2 describes the features that can be parameterized.
The ChipScope PLB IBA peripheral supports multiple trigger units that connect to the PLB Control bus, Address
bus, Data bus, lumped Slave or Master busses. Each one of these trigger units can be enabled and parameterized
independently. Table 2 lists all the parameters used in selecting the trigger port connections. These parameters
define what signals are connected to the trigger ports, the match unit type, and if the signals are stored in the sam-
ple buffer.
