Obtaining the Host ID for Cadence Allegro X and OrCAD X

Cadence License Server

The Cadence License Server is a key component of Cadence Design Systems software setup, designed to oversee the distribution of software licenses across a network. Think of it as the heart of the operation, ensuring every user who needs to run Cadence's software tools can do so without stepping on each other's toes. It makes certain that the total number of users at any given time doesn't surpass the licenses your organization has. This system is built on FlexNet Publisher, a tool that keeps an eye on license usage, manages the borrowing and returning of licenses in real-time, and gives administrators the power to monitor and report how licenses are being used.

What is a Host ID?

Getting your Cadence software, including OrCAD X and Allegro X, ready to go requires a Host ID. This ID is crucial because it's used to make the license file for your software. 

You will need to decide where your license server will be located. If it's just you using the software, you'll need the Host ID from your own computer. But, if a team is planning to use the software, you'll need the Host ID from a computer on your network. This computer is usually set up by your IT department to make sure everyone who needs to can access it. 

If you're unsure about anything or have questions, it's a good idea to talk to your Account Manager before you send the Host ID.

Obtaining the Host ID

Once you’ve decided which computer will be your license server, you’ll need to get the Host ID from it (this might also go by Physical Address or MAC Address, and it’s unique to your network card). 

We will provide a tool for you, an app called “lmtools.exe,” to help you find this ID. Save it to the computer selected for the license server and run it. Once the application has started, click the System Settings tab. Look for the Ethernet section, and you’ll see a string of letters and numbers.

That’s your HOST ID, and it’s what we need to get your license sorted. If there’s more than one listed, just send us the first one. It should be 12 characters long.

The easiest way to handle this is to click the Save HOSTID Info to a File button, save it with a clear name, like “CompanyName.txt,” and email it to us. We’ll take it from there and get your license ready.

If you hit any snags or have questions, reach out to your Account Manager.
