+design = array containing design name (as the first entry in the array) followed by pointers to modules

+ {array of input names; array of output names; array of nodes; array of boxes,
+ array of floating-point input-arrival times; array of floating-point output-required times}
+node = array containing output name, followed by node type, followed by input names
+box = array containing model name, instance name, followed by pairs of formal/actual names for each port
+
+ Comments:
+ - in describing boxes
+ - input formal/actual name pairs should be listed before output name pairs
+ - the order of formal names should be the same as the order of inputs/outputs in the module description
+ - all formal names present in the module description should be listed
+ - if an input pin is not driven or an output pin has no fanout, the actual pin name is NULL
+ - word-level formal name "a" is written as bit-level names (a[0]. a[1], etc) ordered LSB to MSB
+ - the boxes can appear in any order (topological order is not expected)
+ - in description of nodes and boxes, primitive names should be given as char*-strings ("AndT", "OrT", etc)
+ - constant 0/1 nets should be driven by constant nodes having primitive names "Const0T" and "Const1T"
+ - primitive modules should not be written, but the list of primitives and formal names should be provided
+ - currently only "boxes" are supported (the array of "nodes" should contain no entries)
+ - arrays of input-arrival/output-required times in the module description are optional
