RELEASE NOTES FOR VERILOG 2001 BETA FOR PEOPLE TO TRY 

  This directory contains release of a new code base that supports many
  of the Verilog 2001 features as described in IEEE P1364 Verilog 2001
  Language Reference Manual.

  Cver supports the following Verilog 2001/2005 LRM features:

    1) Implements Verilog 2001 signed evaluation algorithm.  Supports signed
       keyword and signed constants plus handles sign extension during
       expression evaluation.

    2) Support for Verilog 2001 config.  Use the +config [config file name] 
       option to specify the library mapping file.  You can place a file
       named lib.map in your current directory, but that is not recommended
       since it will always silently use that file for configuring your
       design. See tests_and_examples/v2001/config for some small examples.

    3) Supports new file io Unix Stdlib stream file input and output
       operations.
   
    5) Supports new module and task port and module parameter header  
       declarations.  Here is an example:


            module test
             #(parameter integer p1 = 5,
               parameter p2 = 7,
               parameter r1 = 7.3
              )

             (
              input [7:0] a,
              input signed [7:0] b, c, d,
              output [7:0] e,
              output signed [7:0] f,g,
              output signed [7:0] h
             ) ;

             task my_task(input a, b, inout c, output signed [15:0] d, e);
              begin
               c = a;
               d = f;
               e= 2*f;
              end
             endtask
            endmodule

    6) Supports Verilog 2001 implicit event forms @(*) and @*.  Also
       supports events lists with comma as substitute for
       event or.  Now (a, b, c) and (a or b or c) are both legal.
       You can see the result of @(*) by running cver with the -c and -d
       options (-c means compile only and -d means dump internal net list).

    7) Added support for localparams.  The localparam keyword is now
       supported.

  Main missing Verilog 2001 features are multi-dimensional arrays and
  generate.

  See tests_and_example/v2001 for a growing directory of verilog 2001 test
  files.
