design = array containing design name (as the first entry in the array) followed by pointers to modules
module = array containing module name (as the first entry in the array) followed by pointers to 6 arrays:
{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
