Verisium Debug, the Cadence unified debug platform, offers a variety of debugging capabilities, including RTL debug, UVM testbench debug, UPF debug, and DMS debug. From IP to SoC level debug, the user can take the benefits of the rich debugging features to reduce the time for debug.

Not only the common and advanced debug features, Verisium Debug also provides Python-based interface API, which enables capabilities allowing users to customize functions with Verisium Debug Python API to access from design, waveform databases and add functions to Verisium Debug’s GUI for visualization purposes. With Verisium Debug’s Python API, users can turn repetitive works into automatic programs or reduce efforts to create in-house utilities with well-established infrastructure from Verisium Debug.

Here is an example of how the user uses Python API to create a customized function. Users can write a Python program to extract signals in a specific design scope and report the values of the extracted signals. From Fig 1., you can understand the procedure of the traversal steps.

1. Import Python library in Verisium Debug package.
2. Setup the database for traversal.
3. Search the scope with the hierarchy information in the design DB.
4. Query the signal list and the values of the signals.
5. Print out the results.

The result from the Verisium Debug Python App can be used for post-process design checking or fed into other utilities in the design flow.

The concept is very straightforward. With Verisium Debug and the Python API environment enabled, you can easily query any information that is stored in the databases of Verisium Debug. The result can be outputted in text format, or you can also use the API to display the results back to Verisium Debug’s GUI.

The Verisium Debug Python API is an important capability and resource for Verisium Debug users. To make Verisium Debug Python API easier to access, from Verisium Debug 24.10 release, Verisium Debug introduced the new Verisium Debug Python App Store.

The Python App Store includes ready-to-use Python App examples with the availabilities of original source code documents, which help the user to understand how to start writing an app that fits their use case.

The Verisium Debug Python App Store can also be used by a team as an app management system. App creators can share the developed apps across teams within their companies. The in-house created apps will become easy to manage, and engineers can easily access the apps from the central location, which makes it possible for users to see the updated available Verisium Debug Apps from the Verisium Debug App Store.

Verisium Debug Customized Apps with Python API

As a verification engineer, you’re surely looking for ways to automate the debugging process. Have you developed your own scripts to ease specific debugging steps that tools don’t offer? Working with scripts locally and manually is challenging—so is reusing and organizing them. What if there was a way to create your own app with the required functionality and register it with the tool? The answer to that question is “Yes!” The Verisium Debug Python App Store lets you instantly add additional features and capabilities to your Verisium Debug Application using Python Apps that interact with Verisium Debug via the Python API. Join me, Principal Education Application Engineer Bhairava Prasad, for this Training Webinar and discover the Verisium Debug Python App Store. The app store allows you to search for existing apps, learn about them, install or uninstall them, and even customize existing apps.

Hello,


I would like to use the simulation software xrun/simvision that comes with XCELIUM. We are currently using classroom licenses and want to disable all ip addresses on the student pcs except the license server ip. We want to make sure that students cannot copy confidential data from the Cadence tools.


Problem:

When I launch the xrun simulation while all ip addresses are blocked, it starts but the performance is very slow. The GUI starts after 5 minutes and the simulation is ready after 10 minutes. The interesting thing is that when I enable all blocked ip addresses, everything works at a reasonable speed.

Terminal Output (execution without internet connection):

xrun -gui design.vhd

waiting for SimVision/Verisium Debug to connect...


Is there a way to run the simulation tools without an Internet connection? Or can you give me the ip addresses that are used by the simulation tools so that I can enable only those specific ips?


Regards,

Max
