Top 5 Schematic Design Errors (Part 2)

With today’s circuit designs getting more and more complex, there is an ever-greater risk of schematic errors passing through the design flow. As a continuation of February's issue, this month Valydate will reveal the second most common schematic design error.

Error #2: The VOIMAX Error.

Definition: A VOIMAX error occurs when the driver output voltage at "Logic High" (VOH) is less than the receiver’s minimum required value of "High-Level Input" (VIH).

Major Causes: 
This issue can be caused for a variety of different reasons, but the more likely causes are:

  1. It's often due to a driver or receiver chip with a broad supply range powered by a supply at a different voltage level than intended. It could be a simple design oversight, possibly when the driver and receiver are several pages apart in the schematic.
  2. It is sometimes unavoidable to have multiple devices communicating at different voltage levels. A designer could be aware of this requirement during the initial design stage, but forget to implement a level translator for the correct voltage thresholds.
  3. There can be nuances of how different devices define their logic thresholds as not all devices follow the JEDEC logic standards. Manufacturers often define their own thresholds differently and the JEDEC logic standards are used as guidelines. These adjusted threshold levels can cause VOIMAX issues between some driver and receiver device pairings.

Top 5 Schematic Design Errors (Part 1)

With today’s circuit designs getting more and more complex, there is an ever-greater risk of schematic errors passing through the design flow. Have you ever wondered what the most common schematic errors are? As Valydate reviews approximately 15 schematics a month, we decided to share the most common issues we see. Each month Valydate will reveal one of the top 5 schematic design errors and its likely causes.

Error #1: All Inputs (No Drivers) on Net

Definition: The "All Inputs" error occurs when there are multiple inputs on a given net, with no discernible drivers.

Major Causes: This issue can be caused for a variety of different reasons, but the majority and likely causes are:

  1. The simple case of a designer thinking the net is fully connected, when in fact the connection has not been completed.  Connection point indicators are common in CAD tools to assist designers in visually verifying these connections, but they are commonly overlooked when working on large designs.
  2. With net names changing as designers move through various levels of hierarchy and circuit re-use, it gets exponentially more difficult to visually trace signals through a schematic.
  3. FPGA programming not matching the schematic commonly creates an abundance of issues. This mismatch is often caused by lack of collaboration between schematic designers and FPGA programmers.

Nuvation Partners with Valydate for Signal and Power Integrity Analysis

“Nuvation is a perfect partner for us as we complement their design team with our verification expertise. Valydate verification engineers work closely with Nuvation design engineers to ensure that complex electronic designs are right the first time.”

Mark Cianfaglione, CTO of Valydate

January 30, 2017, Sunnyvale, California. Nuvation Engineering has partnered with Ottawa, Canada-based Valydate to reduce the time and effort required for the signal and power integrity analysis phases of high-speed electronic design projects. “On projects where we’re pushing the boundaries of high-speed design, resolving SI and PI issues can significantly impact costs,” said Michael Hermann, COO and VP Engineering of Nuvation. “Following best practices in electronic design is not always enough and issues left for discovery during the prototyping stage can push out project schedules and increase costs. In these situations, we have Valydate perform the SI and PI analysis in simulation before we begin prototyping. This significantly reduces the need for board re-spins and contributes to Nuvation’s impressive track record of first-time-right designs.”

“Valydate specializes in Schematic Integrity, Signal Integrity and Power Integrity analysis for high-speed board designs”, said Mark Cianfaglione, CTO of Valydate. “We have a team of engineers that are fully focused on design verifications using Valydate’s most advanced techniques. Nuvation is a perfect partner for us as we complement their design team with our verification expertise. Valydate verification engineers work closely with Nuvation design engineers to ensure that complex electronic designs are right the first time”.

The partnership has proven to be of mutual benefit for both companies. While Valydate is able to expand their customer base by providing high quality hardware design verification services, Nuvation is able to leverage Valydate’s services and award-winning design verification tools to deliver first-time right designs more quickly and cost-efficiently.

Valydate at DesignCon 2016!

Another successful year at DesignCon!

The crowds poured in as the clock struck 12 with some of the smartest Engineer’s from all over the world.

We were kept on our toes with visits from CTOs, HW Directors, Managers, and Engineers from the top Tier 1 Telecommunication, Aerospace and Defense, Medical Equipment, Consumer Electronics, and Enterprise solutions companies looking for new and innovative solutions to differentiate themselves in their marketplace.

We had lots of interest and requests for demonstration of our schematic review tool, VERA. Our visitors affirmed that an automated schematic reviewer tool was lacking in the marketplace and that no one in the world was offering a tool with all the capabilities like VERA offers.

The Engineers in particular saw the strong value in having a tool that not only saved hundreds of hours of visual inspection and lab debug time but also saved tens of thousands of dollars in re-spin costs. The Directors and Managers saw the potential that our tool enabled them to get to market faster.

Other positive feedback was that our tool was intuitive and straight forward with the intelligence built in to allow for multi board interconnect capabilities

We'd like to thank you all for coming to see us and making the event successful.

We look forward to next year.
