PCB software brings analogue mixed-signal at mainstream prices

Additions to the PADS PCB Product Creation Platform now include analogue, mixed-signal and high speed analysis with PADS AMS Design Suite, PADS AMS Cloud, PADS HyperLynx DRC, and PADS HyperLynx DDR joining the PADS HyperLynx DC Dtop and PADS FloTHERM XT, which the company announced earlier this year.

The analogue, mixed-signal and high-speed analysis products address engineering challenges associated with mixed-signal design, DDR implementation, and electrically correct design sign-off, says the company. They streamline the design process and ensure circuit performance goals are met, reducing the need for prototypes and design re-spins. According to the company, the PADS suites give engineers access to technologies that were formerly out of reach for the mainstream PCB market.

By providing access to essential simulation technologies, engineers can increase complexity in designs. The PADS AMS Cloud reflects the increase in analogue content in products. It is a cloud-based circuit exploration/simulation environment and user community and is available free of charge to PADS users. It allows users to 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 recreate circuits to perform advanced analysis manually.

The AMS Design Suite allows engineers to design and simulate analogue, mixed-signal and digital in one environment. Within one schematic session, analogue circuit simulation leverages VHDL-AMS, (the IEEE standard, and SPICE-based simulation engine), and topology exploration can be performed with the HyperLynx tool. Beyond AMS simulation analysis (DC bias, time-domain, and frequency-domain simulations) 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.

For DDR memory, the PADS HyperLynx DDR option allows engineers to identify and solve signal integrity and timing issues specific to DDRx designs. The DDR Wizard reports consolidated results, with automated whole-bus simulation, streamlined summary pass/fail on entire interfaces, with HTML-based reporting for publication of results.

The PADS HyperLynx DRC tool accelerates the electrical sign-off process by allowing engineers to perform electrical rules checks and identify violations, for confidence that PCB designs are electrically correct before hand-off to manufacturing. With pre-defined rules, issues such as traces crossing voids and traces changing reference planes can be quickly identified, even on the largest designs, says the company. Its rules-based approach identifies non-CAD constraints. There are out-of-the-box checks for EMI, signal integrity, and power integrity and easy identification of violations, says the company.

The PADS release with PADS AMS, PADS DRC and PADS DDR analysis options range from $3,560.00 to $4,995/00.
