map_list Instantiation

For each component instantiation a separate map_list instance is created. To prevent name space pollution a separate name scope for each component instantiation is used. Further, each map_list instance is called ml. The instances will be destroyed automatically when the name scope is left.

Example: The VHDL code

entity incr1 is 
 port (p1, p2 : inout integer);
end incr1;
...
entity incr2 is 
 port (p1 : out integer := 0;
       p2 : in integer := 0);
end incr2;
...
entity top is 
end model;
architecture struct of top is
	signal a, b : integer := 0;
begin
comp1: entity incr1 port map (p1 => a, p2 => b);
comp2: entity incr2 port map (p1 => b, p2 => a);
end struct;

is converted into the following constructor for architecture ``struct'':

/* Architecture constructor */
L7testlib_E3top_A6struct::
L7testlib_E3top_A6struct(name_stack &iname, map_list *mlist) :
  L7testlib_E3top(iname, mlist) {
    ...
    {
     map_list ml;
     ml.signal_map(":p1",NULL,S1a,NULL);
     ml.signal_map(":p2",NULL,S1b,NULL);
     iname.push(":comp1");
     kernel.elaborate_component("","incr1","",iname,&ml);
     iname.pop();
    }
    {
     map_list ml;
     ml.signal_map(":p1",NULL,S1b,NULL);
     ml.signal_map(":p2",NULL,S1a,NULL);
     iname.push(":comp2");
     kernel.elaborate_component("","incr2","",iname,&ml);
     iname.pop();
    }
    ...
};
