NAME

       lofigchain - creates a netlist in terms of connectors on signals

SYNOPSYS

       #include "mlo.h"
       void lofigchain(ptfig)
       lofig_list ∗ptfig;

PARAMETER

       ptfig               Pointer to a lofig_list

DESCRIPTION

       The  lofigchain  function creates the dual representation of natural mbk netlists. In mbk,
       netlists are described in terms of signal attached to connectors.   With  lofigchain,  one
       can  have  the  dual  sight  :  connectors  attached to signals.  This can be very useful,
       depending on the application, but it's also memory consuming on big  netlists,  since  two
       views of the same thing are present in memory at the same time.

       The  information  resulting  of  a  call to lofigchain is present in the USER field of all
       signals of the figure, accessible through ptfig->LOSIG. The USER field has a  ptype  typed
       LOFIGCHAIN,  that  points on a chain_list whose DATA points on each locon beeing connected
       to the given signal.

ERROR

       "∗∗∗ mbk error ∗∗∗ lofigchain impossible : figure ptfig->NAME is interface only"
              In order to be valid, the netlist resulting of a call to lofigchain must be done on
              a figure entirely loaded in ram. See getlofig for details.

EXAMPLE

       #include "mut.h"
       #include "mlo.h"
       void print_netlist(p)
       lofig_list ∗p;
       {
       losig_list ∗s;
       chain_list ∗c;
          lofigchain(p);
          for (s = p->LOSIG; s; s = s->NEXT){
             (void)fprintf(stdout, "signal : index = %ld name = %s\n",
                   s->INDEX, getsigname(s));
             c = (chain_list ∗)(getptype(s->USER, (long)LOFIGCHAIN)->DATA);
             while (c) {
                fprintf(stdout, "conname : %s\n",
                   (locon_list ∗)(c->DATA)->NAME);
                c = c->NEXT;
             }
          }
       }
