fill()
read()
signal_api_call
write()
Prototype:
fill()
.
Arguments:
logic[DATA_W-1:0]
data
.
bit[DATA_W-1:0]
increment
.
bit[CDT_ADDRESS_W-1:0]
address
low
.
bit[CDT_ADDRESS_W-1:0]
address
high
.
Returns:
void
.
Description:
Overwrites the memory content at the starting address specified by
address_low
until
the ending address specified by
address_high
. The
data
field indicates the data value.
The
increment
field indicates the data value increment from one address to the next
address. For example, fill (
data[1]
,
increment[2]
,
address_low[10]
,
address_high[12]
) fills the memory as follows:
■
memory[address=10]
is filled with data value 1
■
memory[address=11]
is filled with data value 3
■
memory[address=12]
is filled with data value 5
Prototype:
read()
.
Arguments:
bit[CDT_ADDRESS_W-1:0] address
.
Returns:
logic[DATA_W-1:0]
.
Description:
Retrieves the memory content from an address you specify.
Prototype:

Description:
Triggers when a client make an API call.
Prototype:
write()
.
Arguments:
bit[CDT_ADDRESS_W-1:0] address
.
logic[DATA_W-1:0] data
.
Returns:
void.
Description:
Overwrites the memory content at an address you specify.
