Creating a portable version usually involves isolating the core binaries and library files. Here are the critical components you need to manage:
The License Manager: Even a portable version requires access to a Cadence License Manager. Portable users often set this up on a central server rather than the local machine.
Core Libraries: Ensure your .lib files (like diode.lib) are contained within the portable folder. If you encounter missing connection warnings, you must use the Associate PSpice Model tool to relink the part to its library file.
Library Configuration: In the Simulation Profile, you can configure libraries as Global, Design, or Profile specific. To maintain portability, setting libraries to "Design" or "Profile" ensures the simulation looks in the local project folder rather than an absolute path on the C: drive. Practical Simulation Workflow
To get the most out of a portable 16.3 setup, follow these steps for a clean simulation: LTspice (free, from Analog Devices) — robust, actively
Enable PSpice Simulation: When starting a new project, always check the "enable pspice simulation" box in the New Project Wizard.
