Subject: stds-1450.4: Action set starter kit


The following is intended as a starting point for defining a set of
STIL.6 Actions.  Minimum requirements are the existence of:

1. integer/boolean symbols

2. logical expressions using operators ! && || == != > >= < <= ()

I'm short on time so i ripped the following out of my header file
comment section.

Action set starter kit:

  ExecIf (Pre Action): if LogicExpr is True, the associated Test and
  either the Pass or Fail Actions are executed, else testing continues
  without executing Pass Actions at the Pass TestFlownode.  Actions
  preceding ExecIf in the ActionList are executed unconditionally.
  Actions following ExecIf, like the associated Test, are executed only
  if LogicExpr is True.
  
  Invert (PreAndOrPost Action): logically invert an IntSym.
  
  InvertIf (PreAndOrPost Action): if LogicExpr is True, then logically
  invert an IntSym.
  
  Assign (PreAndOrPost Action): assign a value to an IntSym.
  
  AssignIf (PreAndOrPost Action): if LogicExpr is True, then assign a
  value to an IntSym.
  
  Bin (Post Action): if the bin associated with this Action is
  SoftwareBin::Default, then set the default Test fail bin if defined or
  generate a WARNMSG if not.  If the bin associated with this Action is
  is SoftwareBin::Undefined, set no bin.  If the bin is any other value,
  then set that bin.  If this is a pass bin continue testing.  If this
  is a fail bin, stop if in production mode, or continue testing if in
  override-on or characterization mode. Accumulate bins if the tester
  allows.  See SoftwareBin::FailBin for predefined failbins (multiply by
  -1, i.e., pass bins are positive numbers, fail bins are negative).
  
  BinIf (Post Action): if LogicExpr is True then set bin "binThen", else
  set bin "binElse".  If "binThen" or "binElse" is SoftwareBin::Default,
  then set the default Test bin if defined or generate a WARNMSG if
  not. If "binElse" is SoftwareBin::Undefined, don't bin ("binThen"
  should never be SoftwareBin::Undefined). If this is a pass bin
  continue testing.  If this is a fail bin, stop if in production mode,
  or continue testing if in override-on or characterization
  mode. Accumulate bins if the tester allows.  See SoftwareBin::FailBin
  for predefined failbins (multiply by -1, i.e., pass bins are positive
  numbers, fail bins are negative).
  
  ActIf (PreAndOrPost Action depending on content): nested and/or
  unsymmetric Action(s) inside an if-then-else form.  If LogicExpr is
  True then carry out Action "actionThen" else carry out Action
  "actionElse".  "actionThen" and "actionElse" may be of type
  ActionList, Assign, AssignIf, Bin, BinIf, or ActIf.
  
  ActionList (PreAndOrPost Action depending on content): represents one
  or more Actions for use with Action ActIf.  The Actions may be of type
  Assign, AssignIf, Bin, BinIf, or ActIf.

Perhaps you noted the absence of a separate "Stop" entity or parameter
to "Bin".  This was merely an admission of impotence: tester
manufacturers do what they want.  This is where a standard mught do some
good.
