Design 3 to 8 decoder in VHDL Using Xilinx ISE Simulator

I am attempting to build a working 8-to-3 line encoder using gate level description in verilog. Although, I have working models, in terms of successful compilation and simulation, the recurring issue seems to be that my circuits just do not seem to implement the encoding and thus the priority as they should do The code was simulated using Xilinx ISE 14.6 tool.

The result is the use of the hybrid VHDL model. VHDL Syntax Coding Style: Behavioral, Data Flow, Structural, Hybrid. The term structural modeling is the terminology that VHDL uses for the modular design: if you are designing a complex project, you should split in two or more simple design in order to easy handle the complexity VHDL is a hardware description language. You can describe the hardware in three different ways using VHDL. 1. dataflow model 2. behavioral model 3. structural mode Write VHDL code in Dataflow modeling for a) 3:8 Decoder using Conditional Assignment Statement (i.e. when - else statement) b) 3:8 Decoder using Selected Signal Assignment statement (i.e. with - select statement

4. Dataflow modeling — FPGA designs with VHDL documentatio

An architecture can be written in one of three basic coding styles: (1) Dataflow (2) Behavioral (3) Structural. The difference between these styles is based on the type of concurrent statements used: A dataflow architecture uses only concurrent signal assignment statements. A behavioral architecture uses only process statements 3 to 8 decoder using 2 to 4 decoder verilog code 3 to 8 decoder using 2 to 4 decoder verilog code

VLSI DESIGN: 3 to 8 Decode

Full adder trial layout. In Figure1 is reported a trial layout on ALTERA Quartus II using a Cyclone V FPGA. The signed full adder VHDL code presented above is pure VHDL RTL code so you can use it independently on every kind of FPGA or ASIC.. In Figure1 Quartus II implement sign extension on input operand, then add them and registers the output result as described in the VHDL code A dataflow model requires that you have a clear understanding of the dataflow(i.e. the physical circuit). However, when using a behavioral model, you only need to pay attention to the main behavior of the design. So a behavioral model is easier to understand and maintain. For example, to implement a parallel multiplier. dataflow mode
