3D Tool Strengthens Marriage of PCB Design 
with Mechanical Design

Cadence Design Systems has announced its Cadence Sigrity 2018 release, which includes new 3D capabilities that enable PCB design teams to accelerate design cycles while optimizing cost and performance. A new 3D Workbench methodology bridges the gap between the mechanical and electrical domains, allowing product development teams to analyze signals that cross multiple boards quickly and accurately.


According to the company, the Sigrity 2018 release enables designers to take a holistic view of their system, extending design and analysis beyond the package and board to also include connectors and cables. An integrated 3D design and 3D analysis environment lets PCB design teams optimize the high-speed interconnect of PCBs and IC packages in the Sigrity tool and automatically implement the optimized PCB and IC package interconnect in Allegro PCB, Allegro Package Designer or Allegro SiP Layout without the need to redraw.



Siemens Acquires Austemper Design Systems

Siemens has entered into an agreement to acquire Austin, Texas-based Austemper Design Systems, a startup software company that offers analysis, auto-correction and simulation technology. This technology allows customers to test and harden IC designs for functional safety in applications such as automotive, industrial and aerospace systems. These are systems where functional safety and high reliability are mandatory for compliance to safety standards like ISO 26262.
ICs in these applications require three types of functional safety verification: for systemic faults, malicious faults and random hardware faults. Mentor's existing Questa software (shown) is a leading technology for functional verification of systemic faults and provides solutions for verification of malicious faults for IC security. The software technology from Austemper adds state-of-the-art safety analysis, auto-correction and fault simulation technology to address random hardware faults. This is expected to complement Mentor's existing functional safety offerings including its Tessent product suite and Veloce platform. Siemens will also integrate Austemper's technology into Mentor's IC verification portfolio as part of Siemens' larger digitalization strategy.

IKALOGIC is giving away an IkaScope! (retail value $379)

The IkaScope WS200 is a pen-shaped battery-powered wireless oscilloscope that streams captured signals to almost any Wi-Fi-connected screen.
The IkaScope WS200 offers a 30 MHz bandwidth with its 200 Msamples/s sampling rate and maximum input of +/-40 Vpp. It provides galvanically-isolated measurements even when a USB connection is charging the internal battery. The IkaScope WS200 will work on desktop computers (Windows, Mac and Linux) as well as on mobile devices like tablets or smartphones. The free application software can be downloaded for whichever platform is needed.

Front-loading of design intent from Design Gateway to Design Force has been achieved by adding an enhanced, unified constraint browser for both applications. This enables hardware engineers to assign topology templates, modify differential signals and assign clearance classes to individual signals. Using a rule stack editor during the circuit design phase, hardware engineers can now load design rules that include differential pair routing and routing width stacks directly from the design rule library into their schematic. Here they can modify and assign selected rules for improved cross talk and differential pair control. Finally, an enhanced component browser enables component variants to be managed in the schematic, and assigned in a user-friendly table.
