    8 bit ALU verilog codes are needed

    This is sample code. but division operator symbol wont work in xilinx for division you should write using algorithm only module alu_code(clk,reset, a,b,out, sel); input clk,reset; input [7:0] a,b; input [1:0] sel; output [8:0]out; reg [8:0]out; always @(posedge clk) if(reset) out =...

    compilation & simulation problem of SystemVerilog

    system verilog compilation Hello friends, I am in the learning stage of System Verilog, using Modelsim -6.2g version, But it is not going to Compilation & simulation, Will this software work for System Verilog or not? are there any other tools which is supporting System Verilog code. Any...

    Why PMOS and NMOS are sized equally in a Transmission Gates

    why pmos size is 2times nmos in layout purpose its ok .... but will it defect on speed of operation, because mobility of pmos is less than the nmos.

    Why PMOS and NMOS are sized equally in a Transmission Gates

    beta ratio of pmos to nmos Actually NMOS width is 2 times less than PMOS width in CMOS logic designs, but in one article I observed PMOS and NMOS are sized equally in a Transmission Gates.......... is it correct??????????? is it possible only in transmission gates or any other circuits...

    $monitor system task in verilog

    $monitor in verilog We can use $monitor and $display in verilog This $monitor will display the output when the variables are changing values with respect to time, $ display is like a printf statement in C language.
