What is post-silicon validation methodology?

What is post-silicon validation methodology?

Post-silicon validation involves operating one or more manufactured chips in actual application environments to validate correct behaviors over specified operating conditions. The objective is to ensure that no bugs escape to the field.

What is pre and post-silicon validation?

During the pre-silicon process, engineers test devices in a virtual environment with sophisticated simulation and emulation tools. In contrast, post-silicon validation tests occur on actual devices running at-speed in commercial, real-world system boards.

What is SoC validation?

The SoC validation process tests the manufactured design chip in a lab setup. The testing is done by using the chip that has been assembled on a reference board to ensure functional correctness. Along with the test board, other components directly relevant to the chip are also tested.

What is silicon design and verification?

Verification is the process of taking an implementation of a chip at some level of abstraction and confirming that the implementation meets some specification or reference design. [

What is Post-Silicon Validation in VLSI?

Abstract: Generally, VLSI Circuits are very complex due to the technology scaling. Post-silicon validation is a critical part of Integrated Circuits. It is the process of finding the bugs that have escaped from the pre-silicon phase.

What is post-silicon characterization?

Post-silicon validation, i.e., physical characterization of a small number of fabricated circuit instances before start of high-volume manufacturing, has become an essential step in integrated circuit production.

What does silicon validation engineer do?

You will lead the laboratory debug of failures with cross-functional teams (Silicon, Boards, Software, Manufacturing). You will measure and optimize performance of silicon, enabling consistent and compelling use-cases in our products.

What is the difference between SoC and ASIC?

ASICs are chip that is basically hardwired to do a specific job. It is not something that can be used for some general-purpose application. SOC → System on Chip. It is basically a cluster / collection or group of different types of processor components like CPU/GPU/Modems/DSP units and memory units.

What is post-silicon bring up?

Many of the methodologies that were earlier considered as post-silicon verification has undergone a shift. They are now part of the pre-silicon function. The bring up of software very often starts long before the silicon tape-out on virtual models or FPGA prototypes.

What is a firmware engineer?

The firmware engineers are the ones who are primarily involved with integrating hardware and firmware together and conducting system tests using near-final hardware and firmware. During this phase, they will occasionally encounter problems that require help from the hardware engineers.

What is the role of silicon validation engineer?

What is validation in FPGA?

Validation consists of testing multiple chips using multiple stress-test patterns (high-switching activity, high utilization, and intensive utilization of the different types of programmable logic blocks) across temperature and voltage to determine “shmoo” plots of performance.

Is firmware engineer a good career?

Embedded Firmware Engineers (or in general Computer Engineers) have excellent job prospects and future growth potential. Recently as the Electronic manufacturing and prototyping cost are coming down, lot of new companies are emerging in hardware domain.

Are firmware engineers in demand?

Demand is on the rise The demand for firmware engineers is ablaze. Many big tech companies are moving to design their own hardware to squeeze performance through optimizations tailored to their products.

How do I become a silicon Validation Engineer?

Key Qualifications

  1. Possess an in-depth understanding of hardware architectures, system level IC design implementation, and knowledge of how to create end use scenarios.
  2. Strong technical background in FPGA prototype emulation, and debug.
  3. Strong technical background in silicon validation, failure analysis and debug.

What are different ways to validate the design?

Basics of Design Validation Process Activities can include: Comparing with similar equipment performing for similar purposes. Simulating functionality through mathematical modeling. Testing the final design to prove the system operates as defined in the user needs.

Is verification and validation the same thing?

Validation is the process of checking whether the specification captures the customer’s requirements, while verification is the process of checking that the software meets specifications.

What is post-silicon validation and why does it matter?

Post-silicon validation is widely acknowledged as a major bottleneck in SoC design methodology—many recent studies suggest that it consumes more than 50% of an SoCs overall design effort (total cost) at 65nm technology. This problem is expected to get worse as the industry continues to move to even smaller geometries.

What is the most critical roadblock in post-silicon validation?

The most critical roadblock in post-silicon validation is the limited observability of internal signals of a design, since this aspect hinders the ability to diagnose detected bugs.

Why are critical trace signals important for post-silicon validation?

Due to the limited space of the available trace buffer, selection of the critical trace signals plays an important role in both minimizing the number of signals traced and maximizing the observability/restorability of other untraced signals during post-silicon validation.

What is the validation process?

Validation includes different tasks such as functional correctness, adherence to power and performance constraints for target use-cases, tolerance for electrical noise margins, security assurance, robustness against physical stress or thermal glitches in the environment, and so on.
