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, or VLOG real
NOW	Returns the value of time at the current location in the WLF file as the WLF file is being scanned (not the most recent simulation time).
