It supports verification and testing of hardware designs at any level of abstraction. The goal of this tutorial is to familiarize you with Aldec Active-HDL and to help you complete your assignment. The DPI-C wizard allows you to enter the names of DPI-C tasks and functions, their arguments name, type, mode, and, optionally, the default value and range. Ask Us a Question x.

Active-HDL 8.1 EE
The Counter stimulator can be applied to VHDL signals of one-dimensional array types and integer types and Verilog integer registers and vectors. A 1 year support contract is included with the purchase of TBL license. This allows complete automation of the design verification process, particularly when combined with other simulation entry methods.
The Clock stimulator produces a rectangular wave defined by the following parameters:. You can also invoke custom commands developed in Script Basic, which are included with Active-HDL, for automation purposes.
Active-HDL supports the following methods of stimulating or forcing input signals actiive the simulation: SystemVerilog is a set of extensions to the Verilog HDL that allow higher level of modeling and efficient verification of large digital systems. What do you do if you have checked your design, compiled successfully, and when you run your simulation, your results are flawed?
This type of the stimulator also can be applied by using the force macro command. X-Trace helps you quickly identify the cause of unexpected values by reporting information on changes from valid to unknown, uninitialized, or user-defined values in the simulated model.
Similarly, any changes in the file means the file cative to be saved and recompiled prior to restarting the simulation. Even though this tutorial will show you all you need to know to do basic designs and complete the assignment, you should experiment with Active-HDL on your own.
A testbench for any design hrl can be generated from waveforms created in the waveform editor or during a simulation run. Active-HDL provides a macro command language for manually entering simulation commands, such as forcing signal values, assigning formulas and executing simulation steps. Powerful testbench generation automation features have been provided to speed functional verification.
Your final design should look similar. All these methods providing design stimuli can be combined in the same design.

Using standard design source encryption is a much easier form of managing IP creation and delivery than any kind of binary file encryption. The simulation macro commands can be executed from a file, saving you time on the manual entry of every command in the Console window. You will find that hfl are many tools and options that have been left out of this tutorial for the sake of simplicity.
You can edit the wizard-generated file; adding your own test scenario and additional inputs, if required. Perform hdk and repetitive task by simply moving the mouse.
It returns integer values distributed according to standard probabilistic functions. When you run the check diagram tool, a DRC report file is created. X-Trace X-Trace helps you quickly identify the cause of unexpected values by reporting information on changes from valid to unknown, uninitialized, or user-defined values in the simulated model.
Assertions Debugging Design and verification engineers who implemented assertions and covers in their project can observe their behavior during regular simulation and debugging in multiple windows. However, your file in the Design Browser is still preceded by a question mark.

The goal of this tutorial is to familiarize you with Aldec Active-HDL and to help you complete your assignment. The icon enabling the comparison of signals is located in the upper part of the window.
The Custom stimulator forces a signal or net with its own waveform the waveform must already exist in the Standard Waveform Editor window before simulation.
