makaimann abf5930a33 Add btor ops for $mul, $div, $mod and $concat 2018-12-17 10:45:17 -08:00
whitequark ca866d384e write_verilog: handle the $shift cell. 
The implementation corresponds to the following Verilog, which is
lifted straight from simlib.v:

    module \\$shift (A, B, Y);

    parameter A_SIGNED = 0;
    parameter B_SIGNED = 0;
    parameter A_WIDTH = 0;
    parameter B_WIDTH = 0;
    parameter Y_WIDTH = 0;

    input [A_WIDTH-1:0] A;
    input [B_WIDTH-1:0] B;
    output [Y_WIDTH-1:0] Y;

    generate
        if (B_SIGNED) begin:BLOCK1
            assign Y = $signed(B) < 0 ? A << -B : A >> B;
        end else begin:BLOCK2
            assign Y = A >> B;
        end
    endgenerate

    endmodule

Jim Lawson 93d19dc2fb Add support for module instances. 
Don't pad logical operands to one bit.
Use operand width and signedness in $reduce_bool.
Shift amounts are unsigned and shouldn't be padded.
Group "is invalid" with the wire declaration, not its use (otherwise it is incorrectly wired to 0).

Use `realpath` 
Use `os.path.realpath` instead to make sure symlinks are followed. This is also required to work for nix package manager.

Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)
