How to manage large VHDL testbenches - Stack Overflow
Dec 9, 2013 · General control and status: Reusable test bench specific procedure, for example reset of device under test and test bench support modules. Reusable procedures: Does not control or use test bench signals directly, but only through procedure arguments. These procedures may be located in packages (other files) for reuse in other test benches.
Running multiple testbenches for VHDL designs - Stack Overflow
Whenever I create a VHDL design I tend to have many modules. Each of these modules are then connected to one main file and so everything is synthesised. But I want to write seperate test benches fo...
vhdl - Is it possible to define looping functions in a test bench ...
May 24, 2020 · VHDL for test bench can be more software like, since it does not need to be synthesizable. The ´y´ part can be written with loop as shown below, and the other parts can be made in a similar fashion. library ieee; use ieee.std_logic_1164.all; entity tb is end entity; architecture sim of tb is signal y : std_logic; begin process is constant period : time := 80 ns; constant steps : natural := 8 ...

Testing VHDL / FPGA Using Python and A Simulator
Mar 2, 2016 · The standard way to test VHDL code logic is to write a test bench in VHDL and utilize a simulator like ModelSim; which, I have done numerous times. I have heard that instead of writing test benches in VHDL, engineers are now using Python to test there VHDL code.
VHDL - test bench - generics - Stack Overflow
Jan 15, 2016 · I've been working on making a decoder that I can use in multiple instances by just changing a generic value for the size of the input/output vector. The decoder will 'sll' a single bit, a number of positions based on the integer conversion of the input. The decoder itself works fine. The problem arrises when I make a test bench and compile.
