#------ CLOCK ENABLE SETUP/HOLD TIME CHARACTERIZATION --------------------------
#-------------------------------------------------------------------------------
# The syntax are the same as the Perl language. Any
# valid Perl expression can be used. In fact, this file is
# executed directly, so the order of the definitions is
# important: Be sure the '&autochar' command, which is actually
# a subroutine call to the function 'autochar', is called after
# the necessary definitions are made.
#-------------------------------------------------------------------------------
# Any of the global defaults may be changed here. See
# $AUTOCHAR/lib/defaults.pl for a list of what they are.
# $spice_cmd = 'hspice';
# $techpath = '/path/to/spice/libraries';
# $spice_corner = 'hspice.ttlh';

# $scale_cload = 0.66e-15;
# $scale_delay = 0.060e-9;
# $trans_period = '2ns';
# etc.

# List of the terms to the cell. Order is unimportant.
# Each name is prefixed by a ":x" letter to indicate type:

# with in1 being the reference.
# $equivalent{'in0'} = 'in1';
#-------------------------------------------------------------------------------
# Define the output loads.
# Specify the loads for the output(s) that are not being characterized.
# If 'none' is specified, then no output loading is added. Use
# the words 'cap:', 'res:', or 'subckt:' to indicate an output load that

# and relative output results function variance for convergence.
# See the hspice 'Optimization' chapter for details.

# if the voltage of the internal node is >= the specified percentage
# of its final value, then it is said to be passing. If

# &autochar ( <d>, <cetype>, <ce>, <clktype>, <clk>, <qtype>, <q>, <ctype>, <c>,
# [ <tie>, <unused>+] );

# <q> = name of the flop data output term
# <ctype> = either 'inverting' or 'non_inverting' w.r.t. d
# <c> = name of the internal criterion node
#
# Optional:
# <tie> = how to tie the other inputs, either 'tie_high' or 'tie_low'
# <unused>= name(s) of the inputs to be tied. These are regular
# perl expresssions. Be sure to write brackets [ and ]
# as \[ and \], respectively. < and > are ok.

# and to copy the data from another set of arcs instead. The general form is:
# ©char (<cetype>, <ce>, <clktype>, <clk>, <refce>, <refclk>);
# ©char (
'active_high', 'ce',
'falling', 'ph1_b',
'ce', 'ph1');
