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;

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 terminates.
       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();
       }
