NAME

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

SYNOPSIS

10       #include <genlib.h>
11       void GENLIB_DEF_PHSC(cellname)
12       char ∗cellname;
13

PARAMETERS

15       cellname            Name of the netlist figure to be looked for in mem‐
16                           ory or on disk, for futher physical placement.
17

DESCRIPTION

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

EXAMPLE

37       #include <genlib.h>
38       main()
39       {
40            /∗ Create a figure to work on  ∗/
41            GENLIB_DEF_PHSC("mycell");
42            /∗ Place an instance ∗/
43            GENLIB_SC_PLACE("instance", NOSYM,0L,0L);
44            /∗ Save all that on disk ∗/
45            GENLIB_SAVE_PHSC();
46       }
