Type 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.)
Variable Type
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 logfile as the logfile is
being scanned (not the most recent simulation time).
Variable Type
Name of a signal -- VHDL signals of type bit or std_logic_vector
-- VLOG register
-- VLOG net array
A subrange or index may be specified in either VHDL or VLOG syntax.
Examples: mysignal(1 to 5), mysignal[1:5], mysignal (4), mysignal [4]
