* $Log: draw_vpi.c,v $
* Revision 1.17 2007/02/14 05:59:24 steve
* Treat BOOL and LOGIC the same according to VPI functions.
*
* Revision 1.16 2007/01/30 05:28:23 steve

* Major rework of array handling. Memories are replaced with the
* more general concept of arrays. The NetMemory and NetEMemory
* classes are removed from the ivl core program, and the IVL_LPM_RAM
* lpm type is removed from the ivl_target API.
*
* Revision 1.13 2005/10/11 18:30:50 steve
* Remove obsolete vvp_memory_label function.
*
* Revision 1.12 2005/07/11 16:56:51 steve
* Remove NetVariable and ivl_variable_t structures.
*
* Revision 1.11 2005/06/18 15:55:21 steve
* Handle signed display of unsigned signals.
*
* Revision 1.10 2004/12/11 02:31:28 steve
* Rework of internals to carry vectors through nexus instead

* down this path.
*
* Revision 1.9 2004/10/04 01:10:57 steve
* Clean up spurious trailing white space.

* Properly pass $signed(signal) to tasks.
*
* Revision 1.5 2003/03/25 02:15:48 steve
* Use hash code for scope labels.
*
* Revision 1.4 2003/03/15 04:45:18 steve
* Allow real-valued vpi functions to have arguments.
*
* Revision 1.3 2003/03/10 23:40:54 steve
