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 Cadence Allegro/OrCAD 17.40 software on Microsoft Windows using CMC CADpass to access shared licenses on the CMC License Management System (LMS). The procedure has been tested on a Windows 10, 64-bit system. Cadence offers Allegro/OrCAD tools for LINUX and Windows operating systems. The full list of CAD modules for university subscribers is available upon request. Contact for details.

The Allegro/OrCAD package includes:

  • Allegro Design Entry (Capture, Capture CIS, HDL and System Capture)
  • Allegro/OrCAD PCB Editor and Integrated Analysis and Checking
  • Allegro EDM Solution and ECAD-MCAD Library Creator
  • Allegro/OrCAD PSpice Simulator
  • Allegro Package Designer

Note: Not all modules are available for both operating systems.

Prerequisites for Installing Allegro/OrCAD with CMC License Manager System (LMS)

Before you begin with this installation, you must:

  • Register with CMC Microsystems at:
  • Have your faculty supervisor open an account through the CMC subscription page at:
  • Have administrator privileges for the workstation on which you are installing this software
  • Have a unique login name (LINUX or Windows) that does not contain a blank space. The following are examples of unacceptable login names: admin or administrator, cmcmgr, root, stcmgr, super, sysadm, user, owner, student, guest, temp, and system.

System Requirements


One of the Cadence-supported operating systems is required.


The following is recommended by the Cadence support staff. Better performance is achieved by using a computer with:

  • A dedicated graphics card with OpenGL support, 2 GB dedicated video RAM and a 128-bit bus interface;
  • A minimum of 1 GB physical RAM; and
  • A recent vintage of Intel or AMD CPU.

Subscribers running signal integrity (SI) simulations should use a workstation with more memory than the minimum. Additional recommendations are listed in the “Allegro Platform System Requirements”, Product Version 17.4 – 2019. A copy of this document is available during the installation process. See Figure 2 below for the location of the document link.
