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
|
|
- primitive names should be given as char*-strings in description of nodes and boxes
|
|
- primitive modules should not be written, but the list of primitives and formal names should be provided
|
|
- constant 0/1 nets can be specified as char*-strings "NetConst0" and "NetConst1".
|
|
- arrays of input-arrival/output-required times in the module description are optional
