AFFECT(3)		       GENPAT functions			     AFFECT(3)

       AFFECT, GENPAT Package

       AFFECT ("pattern_date", "ident",	"value");

		 :  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  ex-
		 ample,	if b(3 downto 0) exists, you can affect	"b", "b(3)" or
		 "b 3".	 Path-name must	be  specified  by  the	syntax	:  in-

       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  re-
		 sult  will be a "full star" value. (For example, "0B0*10" and
		 "0B***" would give the	same result.) AFFECT is	doing automat-
		 ically	 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*").

       "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.

       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.

       AFFECT ("0", "b", "0B0");
       AFFECT ("2", "b", "0B1");
       result :		   b
       <      0	ns> :.....0...;
       <      2	ns> :.....1...;
