PADS PCB tool gains analogue/mixed signal high speed analysis
The PADS AMS Design Suite, PADS AMS Cloud, PADS HyperLynx DRC, and PADS HyperLynx DDR products streamline the design process and ensure circuit performance goals are met, Mentor says, reducing the need for prototypes and design re-spins. Mentor asserts, “Combined with the recently announced PADS HyperLynx DC Drop and PADS FloTHERM XT products for power integrity and thermal analysis, respectively, the extended PADS Product Creation Platform gives engineers access to technologies that were formerly out of reach for the mainstream PCB market.”
Analogue/mixed signal simulation is key to the majority of today’s designs, Mentor notes. PADS AMS Cloud – which is a cloud-based circuit exploration/simulation environment and user community – is available FREE for all PADS users. Users from all levels of expertise can create and share analogue, mixed-signal, and mixed-technology designs in an online, collaborative environment where designs and models can be published or downloaded. Circuit designs created in PADS AMS Cloud can be transferred to the PADS AMS Design Suite desktop environment, eliminating the need to manually recreate circuits to perform advanced analysis and drive the PCB design flow.

PADS AMS Design Suite is a complete design creation solution to design and simulate analogue/mixed-signal (AMS) and digital in one environment. Within one schematic session, both analogue circuit simulation in VHDL-AMS, (an IEEE standard, along with a powerful SPICE-based simulation engine), and topology exploration with the HyperLynx tool, can be performed. Beyond common core AMS simulation analysis (DC Bias, time-domain, and frequency-domain simulations) additional extended analysis capabilities are included as standard, such as multi-run parametric sweeps, sensitivity, Monte Carlo, and Worst Case analysis to address specific engineering needs.
Shematic design (including component data management, constraint definition, and variant capability), analogue circuit simulation, and PADS HyperLynx pre-layout analysis are all in a single environment. There is seamless and accurate representation of both electronic and electromechanical elements of a circuit.
DDR memory has become commonplace across the spectrum of electronics designs and is now found in the mainstream markets. By extending the PADS Product Creation Platform to include integrated DDR simulation, the PADS HyperLynx DDR option allows engineers to quickly identify and solve signal integrity (SI) and timing issues specific to DDRx designs in an easy-to-use and affordable environment. It identifies and resolves SI impairments (overshooting/undershooting, ringing) and timing issues (set-up/hold, de-rating, skew, data bus margins). There is easy setup, automated whole-bus simulation, and consolidated results reporting with DDR Wizard, with summary pass/fail judgment on entire interfaces. HTML-based reporting provides design documentation and Web-based publication of results.
Now available for the mainstream PCB design market, the PADS HyperLynx DRC tool accelerates the electrical sign-off process by allowing engineers to perform electrical rules checks and identify violations that will affect the design integrity and performance of the board. With pre-defined rules, issues such as traces crossing voids and traces changing reference planes can be quickly identified even on the largest designs. Integrated electrical DRC technology enables engineers to be confident that their PCB designs are electrically correct before hand-off to manufacturing.
The new PADS release with PADS AMS, PADS DRC and PADS DDR analysis options range from $3,560 to $4,995. For additional information on the PADS Product Creation Platform and these new options, go to www.pads.com
