This example describes how to create a hierarchical design using VHDL. The top-level design, called top.vhd, implements an instance of the function logic.vhd. In the top.vhd file, a component for the logic function is declared inside the architecture in which it is instantiated.

Data-flow (looks more like an Algorithm) modeling is presented in the fourth example. The FIR digital filter algorithm is simulated and synthesized using VHDL. A comparison of the coding styles between the RTL modeling and Algorithm level modeling highlights the different techniques. GCD Calculator (ESD Chapter2: Figure 2.9-2.11)

This example shows how to implement a hierarchical design in lab 15 problem 5. in separet VHDL files in the projected and referenced in a top level module.

This is a practical course that aims to master FPGA and VHDL language through practical projects. It addresses targeting Xilinx devices specifically and FPGA

For loops can also be used to expand combinational logic outside of a process or always block. For that, you need to use a Generate Statement. 2017-11-03 The first VHDL project helps students understand how VHDL works on FPGA and what is FPGA.Some of the VHDL projects are very useful for students to get familiar with processor architecture design such as 8-bit Microcontroller Design in VHDL, Cryptographic Coprocessor Design in VHDL including VHDL ALU, VHDL Shifter, VHDL Lookup Table, Verilog N-bit Adder, etc. In the examples that follow, you will see that VHDL code can be written in a very compact form. However, more experienced designers usually avoid these compact forms and use a more verbose coding style for the sake of readability and maintainability. Synthesizable constructs and VHDL templates example 1). When an aliasdenotes a sliceof an object and no subtype indication is given then the subtype of the object is viewed as if it was of the subtype specified by the slice.
