Johanson Technology Adds Clarity Encryption Support to New Antenna Models

Johanson Technology has collaborated with Cadence to provide customers with encrypted antenna models for Cadence's Clarity 3D Solver electromagnetic analysis solution. Johanson provides antenna models for engineers seeking to include accurate simulation models (Figure 1) to achieve a shorter time to design closure for their end products.

At IMS 2024 last summer, Johanson first introduced the solution, which enables customers to access Johanson's encrypted antenna models directly within Cadence's Clarity 3D Solver (Figure 2). Now, with more models supported, Cadence will also show the latest Johanson Technologies antenna portfolio in Booth 827 at DesignCon 2025, January 28-30, at the Santa Clara, CA Convention Center.

In addition, Cadence and Johanson will be partnering at IMS 2025 this June in San Francisco to once again showcase software simulation results in Cadence booth 1843 and physical measurements in Johanson booth 437.

What Are 3D Components?

A 3D component is an encapsulated model that includes a set of 3D objects, sheets, boundary conditions, and ports/excitations from the Clarity 3D product portfolio (Clarity 3D Solver, Clarity Transient Solver, etc.)

Cadence 3D components solve the problem component vendors have of sharing the level of detail required for complete simulations, even though detail is necessary to realize end products and systems. Designers can create encrypted models that allow customers, partners, and vendors to supply 3D component models, such as connectors, and choose to show the consumer the outer portion of the design without revealing the underlying proprietary IP. At the same time, the solution enables a design ecosystem by incorporating the models into an electronic system design and simulation without revealing the physical IP of the 3D component itself.

Enabling IP Sharing

Once a 3D component is encrypted, it can be shared. As Figure 3 shows, the receiver of the protected IP cannot see the inner workings of the components. The designer has successfully hidden the components' IP from view, guaranteeing IP protection while enabling customers and partners to use these components to carry out their respective multiphysics system-level simulations without any loss of accuracy.
