The October release of Tabby CAD Suite is now available for download.

The read and verific commands now support here-documents in scripts, the same way as read_verilog. This is useful e.g. to have small self-contained tests in a single file such as:

read -sv <<EOT
module top(input clk, output reg [1:0] q);
    wire [1:0] x = 2'b10;
    always @(posedge clk)
        q <= x & 2'b11;
endmodule
EOT
prep -top top
sim -clock clk -n 1 -w top
select -assert-count 1 a:init=2'b10 top/q %i
