vhdl comparator I want to design a 2-bit comparator using VHDL that takes two unsigned std_logic_vectrors A and B and produces bits L,G,E, where L=1 , if AB E=1, if A=B Then Using VHDL, I want to design an 8-bit comparator that uses the 2-bit .the 8bit comparator should have two 8-bit

Oct 31, 2006 #2 A digital comparator’s purpose is to compare numbers and represent their relationship with each other. In this post, we will make different types of comparators using digital logic gates. We will begin by designing a simple 1-bit and 2-bit comparators. The circuit for a 4-bit comparator will get slightly more complex.

I would like to write a code for a comparator in vhdl-ams. Its the first time I use this langage so I'm totally lost (by the way if you know a link with complet lesson on this langage it will be great).

Things to observe: 1. Flip-flop implementation: reset priority, event, rising edge sensitive. 2.

In this tutorial, we will: Write a VHDL program that builds a 1-bit and an 8-bit comparator circuit Verify the output waveform of the program (digital circuit) with comparator circuit operation VHDL Design - Comparator Using IF-THEN-ELSE statement 1.a) The IC magnitude comparator can determines if A equals B, A is greater than B, and A is less than B. Write a VHDL program for a comparator and check the wave forms and the hardware generated. Objective: To understand the working of Comparator; To learn VHDL codin; To understand functional simulation; Theory: A comparator is a combinational circuit that compares two objects and returns the outcome as “equal”, “less then”, or “greater Analog form comparator is voltage comparator.

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.

The single bit output is logic 1 when the two 6-bit input busses are the same; otherwise it is at logic 0. Fig. 6.7.1 : Simple equality comparator. In the above code Extra parentheses enclosing "C /= D or E >= F" means that either one of these conditions and "A = B" must be true for the output to be at logic 1.

My idea was using the Explanation Fig. 2.2: 1 bit comparator Fig. 2.2 is generated by Quartus software according to the VHDL code shown in Listing 2.2. Here, ‘s0’ is the ‘and’ gate with inverted inputs ‘x’ and ‘y’, which are generated according to line 16 in Listing 2.2. Similarly, ‘s1’ ‘and’ gate is generated according to line 17.

Let us start with the design of a simple comparator to start understanding the VHDL language. This will also be out "Hello World" of the HDL. Let us take a look at the following table which describes the behavious of a comparator circuit Table: A one bit comparator
