For Loop Example in VHDL and Verilog, used to extract replicated logic. How to write synthesizable for loops and use in testbench simulations.
一般而言，一个testbench需要包含的部分如下： （1）VHDL:entity 和 architecture的声明；Verilog：module...
When writing testbenches there is no real problem. A good practice when using loops in synthesis code is to keep an eye on the output of your tool and the logic utilization. This is certainly so when you don't have much experience with either VHDL or a specific tool. Regards, jeandel...
I'm trying to implement a sequence in order to use a step motor using VHDL. Since I'm really new to VHDL I can't see what's missing in my code. I want to loop through an array to give the different steps to my variable named motor. I'd appreciate any help. ...

The verification of a VHDL design can be accomplished with the aid of a VHDL testbench at the simulation stage. This testbench is designed to model the working environment into which the VHDL described system or circuit will be placed. When simulated together with the design, the testbench ...

processes. As soon as you start writing testbench code that has time delays in loops, this becomes a very serious problem indeed - and one that is very easily fixed by using locally-declared loop counters. > In that sense the i variable is likened to a generate loop. ...
VHDL verification methodology. The presented solution will use UVVM Utility Library and BFMs, but the principles and mechanisms are 100% general verification methodology; i.e., independent of library and available functionality. Although this testbench is applied on a very simple design under test ...
