Arithmetic Functions
Parameters
Name
Type
Required
Description
aset
Input
No
Asynchronous set input. Default = 0. Sets
q[]
outputs to all 1s, or to the value
specified by
LPM_AVALUE
. If both
aset
and
aclr
are used and both are
asserted,
aclr
is dominant. For outputs such as
q[]
and
eq[]
,
aset
affects
the output before polarity is applied.
Asynchronous clear input. Default = 0. If both
aset
and
aclr
are used and
both are asserted,
aclr
is dominant. For outputs such as
q[]
and
eq[]
,
aclr
affects the output before polarity is applied.
Asynchronous load input. Asynchronously loads the counter with the value on
the data input. Default = 0. If
aload
is used,
data[]
must be used.
This port is provided only for backwards-compatibility in MAX+PLUS II
pre-version 6.0 designs. Altera does not recommend using this port in new
designs.
Counter decode output. Active high when the counter reaches the specified
count value. Either the
q[]
port or
eq[]
port must be connected. Up to c
eq
ports can be used (c
≤
15). Only the 16 lowest count values are decoded.
When the count value is c the
eq
coutput is set high (1). For example, when
the count is 0,
eq
0 = 1, when the count is 1,
eq
1 = 1, and when the count is
15,
eq
15 = 1. Decoded outputs for count values of 16 or greater require
external decoding. The
eq
coutputs are asynchronous.
Data output from the counter. This port is
LPM_WIDTH
wide. Either
q[]
or at
least one of the
eq[]
ports must be connected.

Name

Value
Description
LPM_SVALUE
No
Integer
≥
0
Constant value that is loaded on the rising edge of clock when
sset
is high. Must be used if
sset
is used.
Constant value that is loaded when
aset
is high. This
parameter must be used if
aset
is used. If the value specified
is larger than the <modulus>, the behavior of the counter is an
undefined logic level. The <modulus> is
LPM_MODULUS
, if
present, or 2
LPM_WIDTH
.
The maximum count, plus one. Number of unique states in the
counter’s cycle. If the load value is larger than the
LPM_MODULUS
parameter, the behavior of the counter is not
specified. The default value is 2
LPM_WIDTH
.
If the
LPM_DIRECTION
parameter is used, the
updown
port
cannot be connected. When the
updown
port is not
connected, the count direction is "
UP
". In all other cases, the
default value is
"DEFAULT"
.
Width of the input and output ports. If no output ports are
specified, the value is the number of bits in the count.
LPM_AVALUE

LPM_MODULUS
