NAME

       GENLIB_DEF_PHSC - load a netlist and open a layout model as current figure

SYNOPSYS

       #include <genlib.h>
       void GENLIB_DEF_PHSC(cellname)
       char *cellname;

ORIGIN

       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

PARAMETERS

       cellname 	   Name of the netlist figure to be looked for in memory or on disk, for futher physical placement.

DESCRIPTION

       DEF_PHSC defines the current working figure by it's name, the cellname argument, for layout and netlist operations.  It can be use anywhere
       in  the	genlib program, but must appear at least once at the top of it, since it also initalize the user's preferences through environment
       variables.
       DEF_PHSC looks for the netlist figure cellname in memory, and if not found, on disk. If it fails, an error occurs and  the  process  termi-
       nates.
       The  main  issue  of  this function is to allow the netlist and physical descriptions of a circuit in two separate files, for standard cell
       approach. So there is no need to recreate the netlist view each time the placement changes.
       If the physical figure called cellname doesn't exists in memory, it is created.	If it already exists in memory, it makes  it  the  current
       working	figure.  DEF_PHSC doesn't look on disk for the figure cellname, so be careful not to overwrite an existing file while saving later
       on.

EXAMPLE

       #include <genlib.h>
       main()
       {
	    /* Create a figure to work on  */
	    GENLIB_DEF_PHSC("mycell");
	    /* Place an instance */
	    GENLIB_SC_PLACE("instance", NOSYM,0L,0L);
	    /* Save all that on disk */
	    GENLIB_SAVE_PHSC();
       }
