bit[DATA_W-1:0] increment
bit[CDT_ADDRESS_W-1:0]
address low
bit[CDT_ADDRESS_W-1:0]
address high
Arguments:
void
Returns:
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
