VHDL Testbench Tutorial

Last updated on July 21st, 2017 at 06:42 amVHDL Testbench VHDL Testbench is important part of VHDL design to check the functionality of Design through simulation waveform. Testbench provide stimulus for design under test DUT or Unit Under Test UUT to check the output result. A test bench is HDL code that allows you to

VHDL Component and Port Map Tutorial

Last updated on July 21st, 2017 at 06:35 amVHDL Port Map and Component Component is a reusable VHDL module which can be declared with in another digital logic circuit using Component declaration of the VHDL Code. This helps to implement hierarchical design at ease. Instead of coding a complex design in single VHDL Code. we can divide

VHDL Code for Full Adder

Last updated on October 14th, 2017 at 05:44 pmFull Adder The VHDL Code for full-adder circuit adds three one-bit binary numbers (A B Cin) and outputs two one-bit binary numbers, a sum (S) and a carry (Cout). Truth Table describes the functionality of full adder. sum(S) output is High when odd number of inputs are

VHDL Code for 4-Bit Binary Up Counter

Last updated on July 24th, 2015 at 01:53 pmThe clock inputs of all the flip-flops are connected together and are triggered by the input pulses. Thus, all the flip-flops change state simultaneously (in parallel). VHDL Code for 4-bit binary counter
