SYNOPSIS¶
AFFECT ("pattern_date", "ident", "value");
PARAMETERS¶
- pattern_date
- : pattern date which may be either : integer (absolute
date) or + integer (relative date, the date of the current pattern (last
modified using INIT or AFFECT) is the reference). All dates are supposed
to be expressed in the same time unit which may be set only once using
SETTUNIT.
- ident
- Either the name of a bused signal or a scalar. Vectors must
be referenced with their names only, or bit per bit. For example, if b(3
downto 0) exists, you can affect "b", "b(3)" or
"b 3". Path-name must be specified by the syntax :
instance1.instance11.name
- value
- The value associated with the signal which may be either a
based number (ex. binary: 0b011 ,hexa: 0x3F, octal: 0o56) or a decimal
number. Unknown value (value where a '*' appears), can be used when
dealing with an output, a signal, a register or an input/output when this
last one is to be tested. Star ('*') can appears everywhere in a BASED
number, but the result will be a "full star" value. (For
example, "0B0*10" and "0B***" would give the same
result.) AFFECT is doing automatically the transformation of the value
into a "forced" value or a "tested" value except for
the bidirectional connectors affectation. When and bidirectional is to be
tested, a '?' character must be added before the value (example :
"?0x45f*" instead of "0x45f*").
DESCRIPTION¶
"Affect" a value to a signal. This value will be apllied to the
signal, at the specified simulation date, until the end of the simulation or
until a new value is affected to the signal. Beware : Inputs have to be
affected at the begining of the simulation (first pattern at 0 ps). By
default, signals (except Inputs) are affected with a "full star"
value at the first pattern.
This fonction also set the current pattern.
EXAMPLES¶
SETTUNIT("ps");
AFFECT ("5", "b", "0B1");
result : b
< 5 ps> :.....1...;
At simulation date 0 ps the signal b(3 downto 0) receives the value
"0001". This value will be kept until the end of the simulation if
no more affectation is made.
SETTUNIT("ns");
AFFECT ("0", "b", "0B0");
AFFECT ("2", "b", "0B1");
result : b
< 0 ns> :.....0...;
< 2 ns> :.....1...;
