Storage Functions
lpm_rom
Parameterized Read-Only Memory
The
lpm_rom
function can be used as either
synchronous or asynchronous read-only
memory.
Ports
Parameters
Name
Type
Required
Description
address[]
Input
Input
Yes
No
Address input to the memory. This port is
LPM_WIDTHAD
wide.
Clock for input registers. The
address[]
port is synchronous (registered) when
the
inclock
port is connected, and is asynchronous (unregistered) when the
inclock
port is not connected.
Clock for output registers. The addressed memory content
q[]
response is
synchronous when the outclock port is connected, and is asynchronous when it
is not connected.
Memory enable input. High = data output on
q[]
, Low = high-impedance
outputs.
Memory output. This port is
LPM_WIDTH
wide.

Value
Description
LPM_ADDRESS_CONTROL
No
"REGISTERED"
"UNREGISTERED"
"<filename>"
Controls whether the
address[]
port is registered. The
default value is
"REGISTERED"
.
Name of the MIF or Hex File containing ROM initialization
data ("<filename>").
In general, this value should be (but is not required to be)
2
LPM_WIDTHAD
–1
<
LPM_NUMWORDS
≤
2
LPM_WIDTHAD
. The
default value is 2
LPM_WIDTHAD
.
Controls whether the
q[]
port is registered. The default
value is
"REGISTERED"
.
Width of the
q[]
port.
Width of the
address[]
port.
LPM_WIDTHAD
should be
(but is not required to be) equal to log
2
(
LPM_NUMWORDS
). If
LPM_WIDTHAD
is too small, some memory locations will
not be addressable. If it is too large, the addresses that are
too high will return undefined logic levels.
LPM_FILE

LPM_NUMWORDS
No
