GENLIB_DEF_PHSC.3(October 1, 1997) GENLIB_DEF_PHSC.3(October 1, 1997) NAME GENLIB_DEF_PHSC - load a netlist and open a layout model as current figure SYNOPSIS #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 ar- gument, 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 initialize 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 de- scriptions 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 cre- ated. If it already exists in memory, it makes it the current working fig- ure. 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(); } SEE ALSO genlib(1), GENLIB_SAVE_PHSC(3), GENLIB_SC_PLACE(3), GENLIB_SC_TOP(3), GEN- LIB_SC_BOTTOM(3), GENLIB_SC_LEFT(3), GENLIB_SC_RIGHT(3).
