RIGID-FLEX DESIGN IN ALTIUM DESIGNER

Rigid-flex PCB technology offers a tremendous amount of benefits, including reduced weight, space, increased durability, and reliability. Today’s small, lightweight mil-aero, medical, and consumer electronics products are best implemented with rigid-flex technology. However, not every PCB design tool offers the capabilities necessary for achieving successful rigid-flex PCB designs on time.

What rigid-flex really demands from a PCB tool

Rigid-flex isn’t just about drawing flexible sections in the layer stack. The tool needs to model bend regions, stagger transitions through coverlays correctly, route across the rigid-to-flex boundary without DRC false-positives, handle variable layer counts in different zones of the board, and produce manufacturing data that the fabricator can build from without back-and-forth queries. Indian medical-wearable, defence, and aerospace teams adopting rigid-flex hit each of these stress points within the first few projects.

How Siemens Xpedition handles rigid-flex

GSAS Micro Systems is Siemens EDA’s authorized engineering partner in India. Xpedition Enterprise treats rigid-flex as a first-class design intent rather than a layered drawing exercise, bend regions, coverlay transitions, and per-zone stack-up changes are modelled in the design database, propagated through routing rules, validated against fabricator capabilities through Valor NPI sign-off, and rendered correctly in the 3D view that ECAD/MCAD co-design relies on. Xpedition Standard offers rigid-flex via its token-based add-on for individual engineers and small teams.

The choice for an Indian rigid-flex team usually comes down to project scale: Xpedition Standard with the rigid-flex token covers the typical 4-6 layer rigid section + 1-2 layer flex section that most consumer-electronics and IoT wearables ship. Xpedition Enterprise becomes the right answer when a programme has multiple boards interconnected through rigid-flex (military electronics, advanced medical instruments, satellite payloads), multiple geographically distributed designers on one design, or HyperLynx SI sign-off requirements on the routed product.

I3C FAQ for Firmware Teams: What the Bus Is, What Changes, and What You Need on the Bench

MIPI Alliance describes I3C as the successor to I2C, with legacy compatibility so that I3C and I2C devices can coexist on the same bus, a two-wire interface that supports in-band interrupts to reduce pin count, plus multi-controller support and dynamic addressing. This FAQ answers the questions firmware teams actually ask before adopting it.

Running the Binho Supernova as an I3C Target: Emulating a Device Against Your Own Controller

Binho specifies the Supernova's I3C role as Controller or Target, which means the same adapter can stand in as the device under test rather than only driving one. That second direction is how a team validates its own I3C controller, its ENTDAA implementation and its interrupt handling, before the target silicon exists.

What Happened to Questa Prime and ModelSim?

Siemens has consolidated its Questa verification line under a single brand. The Questa product hub now returns a 301 redirect to the Questa One page, the ModelSim URL redirects to Questa One Sim, and Questa Prime no longer appears on any Siemens public product page. Here is what Questa One actually contains, what Siemens says the word One means, and what Indian verification teams should check before treating this as only a name change.
