* 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.

inp_subcktexpand is the top level function which translates
|
|
.subckts into mainlined code. Note that there are several things
|
|
we need to do: 1. Find all .subckt definitions & stick them
|
|
into a list. 2. Find all subcircuit invocations (refdes X)
|
|
and replace them with the .subckt definition stored earlier.
|
|
3. Do parameter substitution.
|
|
|
|
The algorithm is as follows:
|
|
1. Define some aliases for .subckt, .ends, etc.
|
|
2. First numparam pass: substitute paramterized tokens by
|
|
intermediate values 1000000001 etc.
|
|
3. Make a list global_nodes[] of global nodes
|
|
4. Clean up parens around netnames
|
|
5. Call doit, which does the actual translation.
|
|
6. Second numparam pass: Do final substitution
|
|
7. Check the results & return.
|
|
inp_subcktexpand takes as argument a pointer to deck, and
|
|
it returns a pointer to the same deck after the new subcircuits
|
|
are spliced in.
