IEEE 200X Fast Track Change Proposal

ID:	  FT-07

Proposer:     Steve Bailey (stephen@srbailey.com)

Status:       Open
Proposed:     1-Jan-2003
Analyzed:     Date
Resolved:     Date

Enhancement Summary:     Standard Signal Spy / XMR capability (package/procedural based)
Related issues:          
Relevant LRM section:    


Enhancement Detail:
Based on either the packages from EDA Vendors.
Would need to request donation.

Request:  Compatible with both VCD or VHDL Instance Paths
Request:  Allow relative paths and ".." to be embedded in the string

Proposal 1:  Signal Spy
MTI Signal Spy contains:
  init_signal_driver(src, dest, delay, delay_type, verbose) ;
  init_signal_spy(src_object, dest_object, verbose) ;
  signal_force( dest, value, rel_time, force_type, cancel_period, verbose ) ;
  signal_release( dest_object, verbose ) ;

-- Missing get_value function?
--   difficult to provide a good general purpose routine as 
--   what should the return value be ?String?
Get_Value( dest, verbose) ; -- function that returns value

Proposal 2:  Aliases
-- Some issues, perhaps read only would scope this?
Alias A : std_logic is ":tb:uut:b:d:a_sig" ;
Alias B : std_logic is ":tb:uut:b:" & "d:C_sig" ;
Alias C : std_logic is MY_GENERIC & "d:C_sig" ;

Proposal 3:  Associate with signal direction
signal A : std_logic probe(. . .) ;
signal B : integer drive(. . . ) := 5 ;
