Complete the truth table for a 2-bit comparator. (Table 1) describe the comparator in VHDL. Testbench is a VHDL code, which applies stimulus to design.

Comparator Task: Complete the truth table for a 2-bit comparator (Table 1) and write out the corresponding Boolean equations. Use these equations to describe the comparator in VHDL. Use “when .. else” VHDL statement to describe a 2-bit comparator. Use “with .. select” VHDL statement to describe a 2-bit comparator.

The advantage to this design is that it has VHDL Implementation: --comparator . Here, I have designed, a simple comparator with two 4 bit inputs and three output bits which says, whether one of the input is less,greater or equal to the second input. The code is written in behavioral model.

comparator1bit, we are calling the design of 1-bit comparator to current design. Then, ‘port map’ statements in lines 17 and 19, are assigning the values to the input and output port of 1-bit comparator.

To provide context, it shows where VHDL is used in the FPGA design flow. Then a simple example, a 4-bit comparator, is used as a first phrase in the language.

Total number of Inputs are N, which is always be 2^n (n=2,3,4..).

Hi all! 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).
