ebfm_cfgrd_nowt Procedure
The ebfm_cfgrd_nowt procedure reads up to four bytes of data from
the specified configuration register and stores the data in the BFM shared
memory. This procedure returns as soon as the VC interface module has
accepted the transaction, allowing other reads to be issued in the interim.
Use this procedure only when successful completion status is expected
and a subsequent read or write with a wait can be used to guarantee the
completion of this operation.
BFM Performance Counting
This section describes BFM routines that allow you to access performance
data. The Root Port BFM maintains a set of performance counters for the
packets being transmitted and received by the Root Port. Counters exist
for each of the following packets:
■
■
■
■
The above counters are continuously counting from the start of
simulation. The procedure ebfm_start_perf_sample resets all of the
counters to 0.
PCI Express bus number of the target device
PCI Express bus number of the target device
PCI Express device number of the target device
Function number in the target device to be accessed
Byte-specific address of the register to be written
Length, in bytes, of the data written. Maximum length is four bytes. The
regb_ln
BFM shared memory address where the read data should be placed
Transmitted Packets
Transmitted QWORDs of Payload Data (A full QWORD is counted
even if not all bytes are enabled)
