Constants
Array constants, expressed in any of the following formats
Variables
T
y
pe Values
boolean value 0 1 true false TRUE FALSE
integer [0-9]+
real number <int>|([<int>].<int>[exp] where the optional [exp] is: (e|E)[+|-][0-9]+
time integer or real optionally followed by time unit
enumeration VHDL user-defined enumeration literal
single bit constants expressed as any of the following:
0 1 x X z Z U H L W ’U’ ’X’ ’0’ ’1’ ’Z’ ’H’ ’L’ ’W’ ’-’ 1’b0 1’b1
T
y
pe Values
VHDL # notation <int>#<alphanum>[#]
Example: 16#abc123#
VHDL bitstring "(U|X|0|1|Z|L|H|W|-)*"
Example: "11010X11"
VLOG notation [-][<int>]’(b|B|o|O|d|D|h|H) <alphanum>
(where <alphanum> includes 0-9, a-f, A-F and ’-’)
Example: 12’hc91 (This is the preferred notation because it removes the
ambiguity about the number of bits.)

Name of a signal The name may be a simple name, a VHDL or VLOG style extended identifier, or
a VHDL or VLOG style path. The signal must be one of the following types:
-- VHDL signal of type INTEGER, REAL or TIME
-- VHDL signal of type std_logic or bit
-- VHDL signal of type user-defined enumeration
-- VLOG net -- VLOG register -- VLOG integer -- VLOG real.
NOW Returns the value of time at the current location in the log file as the log file is
being scanned (not the most recent simulation time).
