* re-written by SDB during 4.2003 to enable SPICE2 POLY statements to be processed
|
|
* properly. This is particularly important for dependent sources, whose argument
|
|
* list changes when POLY is used.
|
|
* Major changes include:
|
|
* -- Added lots of comments which (hopefully) elucidate the steps taken
|
|
* by the program during its processing.
|
|
* -- Re-wrote translate, which does the processing of each card.
|

* Please direct comments/questions/complaints to Stuart Brorson:

/*======================================================================*
|
|
* Expand all subcircuits in the deck. This handles imbedded .subckt
|
|
* definitions. The variables substart, subend, and subinvoke can be used
|
|
* to redefine the controls used. The syntax is invariant though.
|
|
* NOTE: the deck must be passed without the title line.
|
|
* What we do is as follows: first make one pass through the circuit
|
|
* and collect all of the subcircuits. Then, whenever a line that starts
|
|
* with 'x' is found, copy the subcircuit associated with that name and
|
|
* splice it in. A few of the problems: the nodes in the spliced-in
|
|
* stuff must be unique, so when we copy it, append "subcktname:" to
|
|
* each node. If we are in a nested subcircuit, use foo:bar:...:node.
|
|
* Then we have to systematically change all references to the renamed
|
|
* nodes. On top of that, we have to know how many args BJT's have,
|
|
* so we have to keep track of model names.
