Designers can open multiple Active-HDL designs simultaneously and integrate them into one super-project. At some point, you may wish to detach files from your design, or delete them completely. Profiler Performance Metrics The Profiler identifies design units or code sections that put the greatest strain on the simulator. We will walk through a simple, yet common, scenario with a schematic that contains errors and warnings. Memory Viewer The Memory Viewer is a debugging tool that has been designed to display memory objects defined in an active design. In large designs where multiple signals must be observed during simulation, keeping them in one waveform window is inconvenient:

You will find that there are many tools actibe options that have been left out of this tutorial for the sake of simplicity. 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.
Before attempting to add more designs beyond the first, which we will do shortly, you need to review the Active-HDL Tips webpage. As you create schematics and other components in your design, you can use the tabs at the bottom of this window to make the corresponding file active in the main window.
Aldec supports both breakpoints in the source code as well as signal breakpoints. Please allow business days for someone alded respond to your question.

Simulation Model Aldec active hdl 8.1 Library protection offers four security levels when compiled models are distributed in the form of library files without releasing their source code. Open this file by going to the DRC line in the Console and double-click the appropriate line see Figure .81 on the next page. Perpetual License A perpetual license is a license with no expiration date. 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.
This is a simplified example of what you may encounter in your design process.
After finishing this tutorial you will know how to:. Notice this schematic file has been added to the design in the Design Browser on the left.
Builds are tested on all the latest platforms to ensure correct operation on users’ workstations. The export process is controlled by a wizard with wide selection of export options allowing creation of hot-linked PDF documentation well suited to any needs. At the top of this window is the Standard toolbar. This information aldec active hdl 8.1 valuable for optimizing the simulation environment and improving performance.
When your design udl first opened, the Design Flow Manager opens in this window.

For now, we will add the first design to the workspace by following the steps provided on the following pages. Signals do not have to be routed via the interface or declared in global packages.
The steps below will show you how to add basic gates to your schematic and how to add single bit input and output terminals, in case you decided not to do so in the design wizard process, or you realized that you are missing some terminals Note: However, you may find it convenient to have more than one workspace in order to organize and manage your designs.
Memory Viewer The Memory Viewer is a debugging tool that has been designed to display memory objects defined in an active design. Powerful testbench generation automation features have been provided to speed functional verification. Dual-language rule library automates the methodology for effective design reuse and verification.
The wizard generates a schematic that is empty aldec active hdl 8.1 for any ports you specified in the design process see Figure SystemC is a C library that extends C to enable hardware modeling.

Remember to use descriptive names. The ability for the simulator to run at bit bus throughput application speeds and utilize extended memory. The Memory Viewer is a debugging tool that has been designed to display memory objects defined in an active design.
Complex FPGA projects are often managed between various teams and require collaboration between team members. Figure 14 is the final version of the actlve you will be drawing.
Remember that this tutorial has ative scratched the surface of the capabilities of this program. Library protection offers four security levels when compiled models are distributed in the form of library files without releasing their source code.
