CADpass client secure connection (will be referred to as CADpass client or CADpass in this document) is a utility provided by CMC Microsystems that creates a secure connection between client PC’s, workstations, and computer sessions, and the CMC managed infrastructure.
This quick start guide provides instructions for installing Siemens Custom IC Tools (formerly Tanner tools) on a Windows 11 system using CMC Microsystems’ CADpass to access shared licenses on the CMC License Management System (LMS).
Prerequisites
You must meet the following criteria before installing Siemens Custom IC Tools:
- Students must register with CMC at https://account.cmc.ca/MyAccount/MyAccount.aspx
- Faculty supervisors can subscribe through the CMC subscription page at https://www.cmc.ca/subscriptions/
- You must have administrator rights for the computer on which you are installing this software
- You must have a unique login name that does not contain a blank space. A username such as “charlie brown” contains a space, while usernames such as “charlie.brown or “charlie_brown” do not contain spaces.

Setting up CADpass Client for Use with Siemens Custom IC Tools
CADpass client is a CMC Microsystems’ license access client and is used by subscribers across Canada to connect to our secure license server(s).
- Follow the instructions in the quick start guide to download and install CADpass client.
- Start CADpass client and then log in using your CMC Microsystems Username and Password.
- When the CAD access window appears, double-click Siemens (formerly Mentor).
A red checkmark appears next to the entry, as shown in Figure 1. Leave this checked while you are using the software.

Obtaining the Software
- Download the Siemens tool from the CMC product page:
https://account.cmc.ca/WhatWeOffer/Design/Tools/DownloadTanner.aspx - Select the version of the tool to download.
This guide uses Custom IC release 2024.3 for Windows as an example.
Installing the Software
To install the tool:
- Open the folder where the file was downloaded.
- Double-click the file *.exe.
- Click Install | Install Products, as shown in Figure 2.

- On the screen Source and Target, select a target location or leave it as the default, as shown in Figure 3.

- Click Next.
- On the screen Product Selection, select the products that you want to install, as shown in Figure 4.

- Click Next.
- On the screen License Agreement, accept the license agreement by clicking Agree, as shown in Figure 5.

- On the screen Confirm Selections, confirm your selections and click Install, as shown in Figure 6.

The Custom IC tool suite begins to install, as shown in Figure 7.

- In the dialogue Desktop Shortcuts, you can create desktop shortcuts by clicking Yes, as shown in Figure 8.

- On the screen Installing Products, when the installation is complete, click Done, as shown in Figure 9.

- Click Exit, as shown in Figure 10, to end the installation.

Running the Software
Ensure CADpass is running and that you have a good connection to CMC Microsystems’ licence servers. From the desktop or Start Menu (“Siemens EDA”), click the tool icon or entry (L-Edit IC, L-Edit Photonics, L-Edit MEMS, etc.) to run the tool that you want to use. If there is an error message regarding licensing, ensure that CADpass client is running and that the Siemens EDA icon has a red checkmark, as shown in Figure 1 above. You can verify your software installation using the Manage Software | Verify Installation option in the Siemens EDA installation GUI.
If you still cannot run Custom IC 2024, then open a support case with CMC staff and we will assist you.
References and Resources to Get You Started
To install a copy of the Siemens InfoHub manuals for Custom IC software, download both the HelpServer executable and the docs-2024* file from the same location where you found the Custom IC installer on the CMC website. Click on the HelpServer executable first to install it. Do not change its default port settings, and do not allow HelpServer to be accessible over a network.
When the HelpServer installation is done, click on the docs-2024* executable. It will proceed to add the InfoHub tutorials and manuals on your workstation.
If you already have the HelpServer available from a previous Siemens EDA installation, then click on the docs-2024* executable, and these references will be added to the HelpServer. These documents can be searched and opened in a browser, as shown in Figure 11.
