HDL generation languages such as MyHDL (Python-based) and Rocket (Scala-based). The concept here is: you describe your design in a higher level language but still using very HDL-ish concepts (e.g. concurrent blocks, explicit timing) and you then generate conventional HDL (usually Verilog-2001).

2014年7月31日 · HVLs tend to be somewhat of a hybrid between HDL and scripting languages. Whereas HDLs are intended to be synthesizeable into a circuit, HVL is intended to be run as software, providing stimulus either to actual hardware or simulated hardware (from HDL) in order to verify correct functionality of the Hardware. Some HDLs have a sort of HVL built-in.

2013年5月12日 · HDL (Hardware description Language) is the type of language used, Verilog/VHDL versus a non-HDL javascript. RTL (Register-transfer level) is a level of abstraction that you are writing in. The three levels I refer to are Behavioural, RTL, Gate-level.

2021年12月10日 · Writing a decent testbench that exercises your HDL design (not program) and checks its outputs, or lets you examine them, should be an integral part of the design process. When you then run the simulation, you can see every single logic node you have named (signals and variables in VHDL) on a wave window.

Verilog -> As an HDL language specifically targets hardware design. Has some levels of abstraction like structural and behavioural Verilog, but it is a very neat form of specifying the RTL of a design. You can definitely synthesize it using a bunch of tools depending on the FPGA you choose (in my case I am using Xilinx Vivado 2014 and Zynq boards).

2019年12月10日 · Exactly what it says: you have a two-dimensional output port which is an unpacked array. This is a packed array: output reg [7:0] FIFO

2014年10月10日 · For the first part of your question, about the motivations of using one or the other: there is a fundamental difference between C and HDLs (VHDL/Verilog). C is a software programming language (as assembly is), VHDL/Verilog are hardware description languages.

2020年4月7日 · To the above answer i would like to add some more , as you writing the synthesizable code i would suggest please use Non-Blocking Assignments for the implementation of Sequential logic (Flip-flops,latches) and blocking assignments for the implementation of combinational logic.you can find the references for the suggestions online .from the code you provided sum is a reg variable and it is ...

2021年9月30日 · I'm teaching myself Verilog with HDLbits and tackling this problem. According to this post, assignment with the LHS of the expression as a concatenation should work. In practice I've used this many...
