Venkateswaran Padmanabhan

Responsibilities

• Lead & manage a team of 15 mixed signal dv & digital design engineers
• Collaborate with cross functional and project managers for project execution and delivering results silicon verification sign-off
• Lead DV for Analog Power Switches TPS25984,TPS25985,TPS25990,LM74900,LM74912,TPS4811 ,TPS4810 family of devices,which involves system to design verification spec mapping , verification test bench development, system verilog test case development, design simulation & design functional & specification compliance verification
• Drive automation initiatives across DV teams with the goal of DV throughput optimization

Key Achievements

• Successful accomplishments in design verification throughput for 30+ Analog power devices released to market in 2.5 years
• MLDV Suite(Rapid Adoption of Machine Learning @Design Verification): Manual waveform review is the biggest bottleneck in DV for every analog schematic iteration. Speed vs Accuracy vs Domain Skill plays a larger role in determining the quality and cycle time of reviews. Automation of the DV waveform review requires golden reference for every analog simulation timesteps & developing a golden device reference model is highly complex as it needs close resemblance to the device. Venkat is the primary inventor and architect of the ML toolkit which creates a DUT golden reference model using simulation logs as training set, Venkat invented a custom ML algorithm to bring formalism into analog space and achieve higher accuracy. Impact since 2020 this led to 100+ weeks cycle time reduction by automating the waveform review of 100K regressions and achieving faster & error free DV waveform review.
• PMBUS UVM Automation (Automated PMBUS digital verification integrated with UVM flow) Verification of physical layer of Telemetry devices involves multiple technical challenges catering to complex and large number of checker development to establish correctness and coverage. Venkat invented the U-DMV (UVM integrated Digital Measurement & Verification) approach which is an integrated one stop solution for PMBUS-VIP integration into U-Made along with automated digital protocol verification and architected a configurable python driven flow through which the level of verification can be configured and can be integrated to simulation Impact : First telemetry product from TI power switch with 0 bugs detected in physical & datalink layer at post-silicon with successful on-time customer sample delivered to IBM, Tejas network, Juniper.

Talent Development

• Mentored 25+ engineers in the areas of pre-silicon design verification through on the job and knowledge share sessions.
• Tech Conference Chair: Collaborated with 20 Tech ladder title holders to solicit and review ~55 papers to choose presentations, posters, and demos for the conference.
  

Responsibilities

• Leading Post Silicon Validation Platforms Development.
• Collaboration with Global Engineering & Cross Functional Teams .

Key Achievements

• VASS (Validation Automation Software Suite): Validation of multiple devices is one of the biggest bottlenecks in post-silicon which requires the right engineering skillset & huge development effort in every product line across TI WW, this involves repeated ramping up of team members on domain skills and automation development effort. Venkat co-architected and developed VASS which is a world-class toolset that is used by every Analog Product line . The VASS identifies the common aspects of every analog product and automates the validation flow for every stage from synchronizing with input definition, validation sequence generation till spec results data upload. Impact with over 700+ devices worldwide the usage of the suite enabled 800+ man months savings across TI for the past from 2017-2020.

Talent Development

• [2017-2020] Mentored 40+ validation engineers across analog product lines through knowledge share sessions on best practices for validation automation development techniques.
• [2019] Conducted Workshop for TI WW 20+ engineers on TestStand Semiconductor Module which enables multisite programming for wafer-level and final package test applications .
