Analog and mixed-signal engineers design the circuits that connect a chip's digital logic to the physical world: data converters, clock generators, high-speed transceivers, power management and I/O. Their work uses different methods and tools from the digital flow that the rest of ChipVerify teaches, and it remains one of the most specialized areas of chip design. This article explains where analog engineers fit, what analog designers, layout engineers and mixed-signal verification engineers do according to 2025 and 2026 job postings, and how the field is changing.

Where Analog Work Fits
Most chips contain some analog circuits, even when they are mainly digital: a clock generator, interfaces to memory or other chips, sensors or power regulation. Some chips are mostly analog, such as power management and data converter chips. Analog chips are a large market of their own: in 2025, analog chip sales were about 87 billion dollars, and the industry's forecast expected them to grow about 10 percent in 2026[1]. Large analog companies earn most of their revenue from industrial and automotive customers; one reported 45 percent of its fiscal 2025 revenue from industrial and 30 percent from automotive markets[2].
On a mostly digital chip, analog circuits usually arrive as finished layout blocks, designed by an analog team or licensed as IP, which the digital teams place and connect, as Buy, Reuse or Build: Choosing IP describes. Analog and digital engineers meet at the boundary: agreeing interfaces, modeling the analog blocks for digital simulation, and checking that the combination works.
Analog Design Engineers
Analog and mixed-signal design engineers design circuits at the transistor level and simulate them with circuit simulators. Postings describe designing, simulating and optimizing transistor-level circuits such as data converters, high-speed I/O and power circuits, with commercial circuit simulators, and often ask for five or more years of experience[3][4]. Unlike digital design, where a language description is synthesized into gates, analog circuits are designed by choosing and sizing individual transistors, resistors and capacitors to meet specifications such as noise, accuracy, speed and power.
Analog Layout Engineers
Analog layout engineers draw the physical layout of analog circuits by hand with layout editors. Postings describe custom layout of blocks such as amplifiers, data converters, PLLs, bandgap references and voltage regulators; careful placement for matching, shielding and routing to control parasitics; checks for electromigration and voltage drop; and physical verification against design rules and the schematic[5][6]. At advanced nodes, postings also ask for knowledge of layout-dependent effects and multi-patterning rules, and of protection against electrostatic discharge and latch-up. Experience asked for typically ranges from three to ten years[5][6].
This is one of the clearest differences from digital work. Digital layout is almost completely automated, while analog layout is still largely done by hand and depends heavily on the engineer's expertise[7][8].
Quick Check
Q: Why does analog layout remain largely manual while digital layout is automated?
Show Answer
Analog circuits depend on precise matching, parasitics and physical effects that general automated tools have struggled to handle, so engineers place and route them by hand. Digital logic tolerates these effects within timing margins, so it can be placed and routed automatically.
Mixed-Signal Verification Engineers
Mixed-signal verification engineers check that digital logic and analog circuits work together. Postings from 2026 describe building models of analog blocks in SystemVerilog real-number modeling or Verilog-AMS, running co-simulation of digital RTL with analog models or transistor netlists, choosing how detailed each model must be to balance accuracy against simulation time, and building UVM test environments around them[9][10][11]. These roles range from entry-level positions to eight or more years of experience[9][10], and they combine the digital verification skills described in Verification Roles with an understanding of analog behavior.
Where Is This Used?
Analog engineers work at analog and power companies, at automotive and industrial chip makers, at companies building high-speed interfaces and data converters, and in the analog teams of large SoC companies. A 2025 report on India's design centers described steady demand for analog alongside digital design and verification[12], and market research lists analog and mixed-signal design among the specialties with the fewest available engineers[13].
How the Field Is Changing
EDA vendors have begun to apply AI to analog work. In 2026 one vendor launched AI-based analog layout synthesis, comparing it to how logic synthesis automated digital design decades ago, and reported faster layout in early deployments; these are vendor-reported results[14]. Researchers have also proposed analog flows that reuse digital place-and-route engines for parts of analog layout[8]. How much these tools change day-to-day analog work is still to be seen.
What This Site Covers
ChipVerify focuses on modern digital design and verification: RTL, verification, synthesis, timing, physical design and test. Its tutorials do not teach transistor-level analog design or analog layout. They are still useful to analog and mixed-signal engineers for the digital side of their work: Verilog and SystemVerilog for models and test environments, UVM for mixed-signal verification, and Digital Fundamentals, which includes CMOS and transistor basics.
Quick Check
Q: What modeling choices does a mixed-signal verification engineer make, according to postings?
Show Answer
Whether to represent each analog block with a real-number model, a Verilog-AMS model or the transistor netlist in co-simulation, trading accuracy against simulation time.
