NAME

loadphfig - load a new physical cell model from disk

See the file buster/alliance/alc_origin.1.en.gz.

SYNOPSYS

#include "mph.h"
void loadphfig(ptfig, figname, mode)
phfig_list ∗ptfig;
char ∗figname;
char mode;

PARAMETERS

ptfig: Pointer to an allocated but empty phfig
figname: Name of the figure to be loaded
mode: Loading mode

DESCRIPTION

loadphfig fills the phfig pointed to by ptfig with the contents of a disk file called figname. The loading mode may be either 'A', then the entire content is parsed, or 'P' then only connectors, abutment box, and through routes are loaded, or 'C', that finishes to fill an already loaded figure in 'P' mode, in order to have it all in memory. This last mode allows to keep the same ptfig pointer when reaccessing the same file.
The loadphfig function in fact performs a call to a parser, choosen by the MBK_IN_PH(1) environment variable. The directories seached for the file are first the one set by MBK_WORK_LIB(1) and then, in the described order, the ones set by MBK_CATA_LIB(1). See MBK_IN_PH(1), MBK_WORK_LIB(1), MBK_CATA_LIB(1) and mbkenv(3) for details.

ERRORS

Some errors resulting from a call to loadphfig are due to the parsers, and are prefixed by the parser format (pf).
"∗∗∗ mbk error ∗∗∗ not supported physical input format 'xxx'"

The environment variable MBK_IN_PH is not set to a legal physical format.

"∗∗∗ mbk error ∗∗∗ pfloadphfig : could not open file figname"

No file called figname.ext, where ext is the file format extension, has been found in the directories set by the environment.

"∗∗∗ mbk error ∗∗∗ pfloadphfig : syntax error line x parsing figname.ext"

Either the file has been corrupted and its syntax is not legal, or there is a bug in the given parser.

EXAMPLE

#include "mph.h"
phfig_list ∗get_the_phfig(figname, mode)
char ∗figname;
char mode;
{
phfig_list ∗pt;
	for (pt = HEAD_PHFIG; pt; pt = pt->NEXT) /∗ scan figure list ∗/
		if (!strcmp(pt->NAME, figname))
			break;
	if (!pt) { /∗ figure doesn't exist ∗/
		pt = addphfig(figname);
		pt->MODE = mode == 'A' ? mode : 'P';
		loadphfig(pt, figname, pt->MODE);
		return pt;
	}
	if (ptfig->MODE != 'A') { /∗ figure exists interface only ∗/
		if (mode == 'A') {
			pt->MODE = 'A';
			loadphfig(pt, figname, 'C');
			return pt;
		} else
			return pt;
	} else /∗ figure exists interface and body ∗/
		return pt;
}
