Behavioural VHDL code for 2-Bit comparator / VHDL behavioural code for two bit comparator - YouTube. This video shows how to write the behavioural code for 2-bit comparator with the help of neat

magnitude comparator and parity generator. presented by:- aparna department of electronics engineering (vlsi & es) topics adc0804 adc features pin diagram & discription adc0804 interface schematic & timing diagram vhdl code & simulation result I need to make an 8-bit comparator in VHDL that lets you know if the two 8-bit numbers (A and B) are equal, or if one is greater than or less than the other. Still very new to VHDL coding, so I'm having trouble a bit of trouble with this. What I'm doing is I have 8, 1-bit comparators with each of their inputs going into the 8-bit comparator. • VHDL Editor • Synthesis Tool • Constraint Editor • Place and Route (PAR) / Fitting Tool • VHDL Simulator – Functional/Behavioral simulation – Logic Simulation – Timing Simulation • Static Timing Analysis Tool Kuruvilla Varghese Data flow Model 14--4 bit equality comparator library ieee; use ieee.std_logic_1164.all; entity Verilog design is declared as component in lines 17-22. Then this component is instantiated in line 26 and 28 to design the 2 bit comparator. The final design generated for the two bit comparator is shown Fig. 7.2 In this way, we can use the Verilog designs in VHDL codes.

Things to observe: 1. Flip-flop implementation: reset priority, event, rising edge sensitive. 2. If and case -- sequential statements -- are valid only within a process.

Explanation of the VHDL code for comparator using behavioral method. How does the code work? A comparator is a combinational logic circuit that compares two inputs and gives an output that indicates the relationship between them. There are three outputs.

Full VHDL code together with test bench for the comparator is provided. The design for the comparator based on the truth table and K-map are already presented here .

VHDL code for a comparator, Full VHDL code together with testbench for the comparator are provided.

First, we will take a look at the logic circuit of the comparator. Then we will understand its behavior using its truth table. And then, we will understand the syntax.

eq is 1 when a=b, gr is 1 when a > b and ls is 1 when a < b. While VHDL executes has concurrent blocks executing in parallel, it is still similar to software programming language like C and Ada. If you have closely watched the schematics above and the verilog code below it, you must have appreciated how VHDL simplifies the process. Before the advent of VHDL, everything was done using schematics.
