Description

As a member of our CAD team, you will architect, develop, maintain and enhance AMS (Analog/Mixed-Signal) simulation methodology and solutions for our analog, RF, and mixed-signal designs. The role requires you to work with different technology nodes and provide flows/methodologies for the different tool sets. You will be collaborating closely with design teams. You will drive and coordinate efforts to develop and validate AMS/co-simulation flows, providing ease of use, speeding up design validation, and ensuring functional silicon.","responsibilities":"Contribute to the direction and development of a state-of-the-art mixed-signal simulation methodology across many different technology nodes and circuit and IC types.

Work directly with world-class custom/transistor-level circuit designers to ensure the expected functional behavior, performance, and interfaces with digital/RTL blocks.

Investigate challenges, propose solutions, complete execution, and drive adoption of novel CAD automations.

Collaborate with third-party EDA tool vendors to ensure their tools meet our high quality standards and extreme performance needs.

Solve critical issues using creativity, knowledge, intuition, and teamwork

Support efforts to bridge the gap between analog and digital domains

Identify risks to design quality and contribute to solutions that close gaps in design execution using simulation and modeling

Preferred Qualifications

Experience with industry-standard AMS tools including Cadence (Xcelium, Verisium/Indago, SimVision, AMS Designer), Synopsys (VCS, Verdi), or Siemens (Questa, Symphony)

Familiarity with analog simulation tools such as Cadence Spectre, Synopsys PrimeSim/HSPICE/Finesim, or Siemens AFS

Ability to identify and address simulation accuracy, speed, and capacity issues

Experience with mixed-signal simulation implementation including discipline resolution, binding, IE setup, Connect Modules, AMSD blocks, wreal, TCL probes, real number modeling, UDNs, etc.

Understanding of behavioral and functional circuit description languages including SystemVerilog, VerilogA, Verilog, Verilog-AMS, VHDL

Familiarity with applying LLMs/AI agents to CAD software development, test generation, and debugging

Understanding of custom IC designs and transistor description formats (SPICE, DSPF, schematics)

Fundamentals in object-oriented programming, data structures, algorithms, system architecture, command-line and GUI interaction, testing/coverage, and revision control

Familiarity with Virtuoso Schematic Editor, PDK content, CDF properties, hierarchy editor, SKILL code, netlisting, and Analog Design Environment (ADE)

Strong communication and presentation skills

Demonstrated commitment to quality and productivity

Minimum Qualifications

Bachelor's degree in Computer Science, Electrical Engineering, Computer Engineering, or related field +0 years of experience

Experience in Python, Perl, or TCL programming

Experience using mixed-signal co-simulation tools
