Constant Description
SHMEM_FILL_QWORD_INC Specifies a data pattern of incrementing 64-bit qwords
(0x0000000000000000, 0x0000000000000001,
0x0000000000000002, etc.)
SHMEM_FILL_ONE Specifies a data pattern of all ones
shmem_write
The
shmem_write
procedure writes data to the BFM shared memory.
Location altpcietb_bfm_driver_rp.v
Syntax
shmem_write(addr, data, leng)
Arguments
addr BFM shared memory starting address for writing data
data Data to write to BFM shared memory.
This parameter is implemented as a 64-bit vector.
leng
is 1–8
bytes. Bits 7 downto 0 are written to the location specified by
addr
; bits 15 downto 8 are written to the
addr+1
location, etc.
length Length, in bytes, of data written
shmem_read Function
The
shmem_read
function reads data to the BFM shared memory.
Location altpcietb_bfm_driver_rp.v
Syntax
data:= shmem_read(addr, leng)
Arguments
addr BFM shared memory starting address for reading data
leng Length, in bytes, of data read
Return data Data read from BFM shared memory.
This parameter is implemented as a 64-bit vector.
leng
is 1- 8
bytes. If
leng
is less than 8 bytes, only the corresponding least
significant bits of the returned data are valid.
Bits 7 downto 0 are read from the location specified by
addr
;
bits 15 downto 8 are read from the addr+1 location, etc.
