Role Overview

The RTL Design Engineer for Mixed-Signal IPs is responsible for developing, integrating, and verifying digital RTL blocks within mixed-signal subsystems that combine analog and digital functionalities. This role requires a deep understanding of digital design principles, interface with analog/mixed-signal teams, and strong verification and integration skills to ensure high-quality, low-power, and functionally robust IP delivery. The engineer will work closely with system architects, analog designers, and SoC teams to enable seamless integration of mixed-signal IPs into complex SoCs.

Key Responsibilities

• Develop synthesizable, high-quality RTL for mixed-signal IPs such as ADC/DAC interfaces, PLL/DLL control, power management units, and sensor front-ends.
• Collaborate with analog design engineers to define digital-analog interface specifications, control logic, and communication protocols.
• Ensure correct functionality and performance of mixed-signal IPs through behavioral modeling, simulation, and co-verification with analog components.
• Participate in design reviews, micro-architecture definition, and documentation of IP functionality and timing interfaces.
• Perform design quality checks including lint, CDC, RDC, and synthesis readiness analyses.
• Collaborate with verification engineers to define test plans, drive coverage closure, and debug issues across digital and analog boundaries.
• Integrate mixed-signal IPs into SoC top-level RTL and resolve functional or timing issues during full-chip validation.
• Contribute to continuous improvement of design methodologies, automation scripts, and reuse strategies for mixed-signal IP development.

Qualifications

• 5–10 years of experience in digital RTL design with strong exposure to mixed-signal IP or subsystem development.
• Proficiency in Verilog/SystemVerilog and experience with synthesis and static verification flows (lint, CDC).
• Familiarity with analog/mixed-signal concepts such as signal sampling, clocking, calibration, and power management.
• Hands-on experience with mixed-signal co-simulation tools (Cadence AMS Designer, Synopsys VCS AMS, etc.) is a plus.
• Good understanding of digital communication protocols (SPI, I2C, APB, AXI).
• Exposure to scripting (Python, Perl, TCL) for automation and design flow enhancements.
• Experience working in cross-functional environments involving analog, verification, and SoC integration teams.

Education

• B.E./B.Tech or M.S./M.Tech in Electrical Engineering, Electronics, or Computer Engineering.

Key Competencies

• Strong understanding of digital design and verification fundamentals.
• Ability to work effectively across analog and digital domains in a collaborative environment.x
• Excellent debugging, problem-solving, and analytical skills.
• Good communication and documentation abilities.
• Passion for quality, efficiency, and innovation in mixed-signal IP design.

Success Metrics
