IEEE P1164 Working Group - Change Proposal

ID:	  CP-008

Proposer: Peter Ashenden <peter@ashenden.com.au>
	  (Based on requirements gathering)

Status:	  Proposed (1-Jun-2001)
	  Analyzed (14-Feb-2003)
	  To be resolved

Summary:  Provide formatted I/O with selection of radix

Detail:

(From slides presented at VIUF-1999)

Formatted read and write procedures for integer, bit_vector, and
vector of std_logic types

  type REPRESENTATION is ( any, binary, octal, hexadecimal );

  procedure READ( L: inout LINE; VALUE out std_logic;
		  GOOD: out BOOLEAN; R: in REPRESENTATION := any );

  procedure WRITE( L: inout LINE; VALUE in std_logic;
		   JUSTIFIED: in SIDE:= RIGHT; FIELD: in WIDTH:= 0;
		   R: in REPRESENTATION := any);


Workshop summary

  - Yes, let's do write, read doesn't seem necessary


Analysis:

	By Peter Ashenden <peter@ashenden.com.au>, 14-Feb-2003

	The need for overloaded read and write procedures for standard
	logic scalar and vector types is now widely met by the
	std_logic_textio package developed by Synopsys, Inc.  CP-007
	proposes inclusion of that package in the standard.  Doing so
	makes this proposal redundant, and so it is rejected.


Resolution:

[To be determined by the P1164 Working Group]
