This vector file simulates the double loop state machine 
specified in dblloop.tdf.

UNIT ms;      % Set the time units to milliseconds. %
START 0;      % Set the starting time for the simulation. %
STOP 250;     % Set the stopping time for the simulation. %
INTERVAL 5;   % Step corresponds to a 100 Hz clock. %
GROUP CREATE state = c1 c0;  % Create a group to represent
                               the state numerically. %
RADIX HEX;    % Set the radix for the group (state) output. %
INPUTS clock reset move cw/ccw goright;
OUTPUTS left state;     % Include the state in the output list. %
% A BURIED statement could go here. %
% A COMB (combinational) statement could go here. %
% A MACHINE statement could go here to specify a state machine's
  secondary inputs (CLOCK, PRESET and RESET) if the file was to
  be imported into a .wdf file. %
% A REGISTER statement could go here to specify a node in a 
  preceding OUTPUTS or BURIED statement is driving a register
  and to specify the register's secondary inputs (CLOCK, PRESET 
  and RESET) the file was to be imported into a .wdf file. %

% Use a pattern statement to specify the vectors to be used in
  the simulation. %
