The following procedures and functions are available in the VHDL
package altpcietb_bfm_rdwr.vhd or in the Verilog HDL include file
altpcietb_bfm_rdwr.v. These procedures and functions support issuing
memory and configuration transactions on the PCI Express link.
All VHDL arguments are subtype NATURAL and are input-only unless
specified otherwise. All Verilog HDL arguments are type INTEGER and
are input-only unless specified otherwise.
BFM Read and Write Procedures
This section describes the procedures used to read and write data among
BFM shared memory, endpoint BARs, and specified configuration
registers
ebfm_barwr Procedure
The ebfm_barwr procedure writes a block of data from BFM shared
memory to an offset from the specified endpoint BAR. The length can be
longer than the configured Maximum Payload Size; the procedure
breaks the request up into multiple transactions as needed. This routine
returns as soon as the last transaction has been accepted by the VC
interface module.
Address of the endpoint bar_table structure in BFM shared memory
Number of the BAR used with
Address offset from the BAR base
BFM shared memory address of the data to be written
Length, in bytes, of the data written. Can be 1 to the minimum of the bytes
remaining in the BAR space or BFM shared memory
Traffic class used for the PCI Express transaction
PCI Express Compiler Version 6.1
