In addition to the interface of a circuit with its environment, we need to describe the functionality of the circuit. In Figure 1, the functionality of the circuit is to AND the two inputs and put the result on the output port. To describe the operation of the circuit, VH...
“I just like to send you a big Thank You for your amazing EditPad Pro text editor. Well, ‘text editor’ is already an understatement, but you know that better than me.” “I am by no means a programmer but learning the ropes of handcoding HTML and CSS. While I am a registered ...
What are the advantages of using VHDL vs Verilog for FPGA design? VHDL tends to be preferred for larger ASIC and FPGA designs requiring rigorous verification for manufacturability. Verilog started as a simulation language and is popular with front-end designers. Key differences: ...
Among the challenges of writing HDL is the requirement of being an expert in all of areas of the language. In addition, the VHDL language, which may be used with SystemVerilog components, has its own separate syntax. SystemVerilog and VHDL are both known as compiled languages. In other word...
It is worth mentioning that VHDL is known for its strong type checking and rich set of built-in data types. On the other hand, Verilog offers a more concise syntax and is highly efficient for synthesizing complex digital designs. SystemVerilog combines the strengths of both VHDL and Verilog,...
Well, chiefly because this is MY dream computer, and I happen to already like coding for the 6502. Also, because what I’m really looking for is a modern successor to the C64 made from modern off-the-shelf parts. A Z80 would hardly qualify. Reply Han on April 15, 2018 at 5:20...
Without referring to VHDL 2008 features, a good VHDL coding style might look like this - don't use legacy libraries STD_LOGIC_UNSIGNED or STD_LOGIC_SIGNED - use numeric data types signed and unsigned for variables/signals involving numeric operations - you can use to_signed(...
1) Complete the design in terms of VHDL coding. 2) Do functional simulation with Modelsim and check that it is OK. 3) Synthesize in QuartusII for cycloneII. 4)The code synthesizes OK. 5)Fetch the post-synthesis netlist and use it in Modelsim for a post-synthesis...
