Cadence VLSI Design and Simulation in India
Cadence is the industry-standard Electronic Design Automation (EDA) platform for VLSI circuit design, analog and mixed-signal IC simulation, custom layout, and physical verification. For PhD and MTech researchers in Electronics Engineering, VLSI Design, Embedded Systems, and Communication IC Design, Cadence Virtuoso is the primary tool for schematic design, SPICE simulation, layout creation, and DRC/LVS verification.
Research using Cadence demands deep familiarity with both the software environment and the underlying circuit theory. Setting up a correct simulation testbench, choosing the right analysis type (DC, AC, transient, noise, parametric), interpreting simulation waveforms, designing a layout that passes DRC and LVS, and extracting post-layout performance data for comparison tables — all require hands-on expertise that takes years to develop through coursework alone.
At E-Clearby Research Consulting Pvt. Ltd., we provide expert Cadence VLSI design and simulation services for PhD scholars, MTech students, and electronics researchers across India. We handle schematic design, SPICE simulation, layout, and verification, delivering accurate, well-documented results that support your research paper and thesis.

What Our Cadence VLSI Design and Simulation Service Includes
Our Cadence engagement covers the complete analog and digital IC design flow from schematic to layout:
Circuit Schematic Design in Cadence Virtuoso
We create accurate circuit schematics in Cadence Virtuoso — CMOS analog circuits, digital logic blocks, mixed-signal systems, or RF circuits — based on your research specification or base paper topology.
SPICE Simulation Using Cadence ADE (Analog Design Environment)
We set up and run all required SPICE simulation analyses — DC operating point, DC sweep, AC analysis, transient simulation, noise analysis, and Monte Carlo — using the foundry-provided SPICE models for your chosen technology node.
Technology Library and PDK Configuration
We configure and use the correct Process Design Kit (PDK) for your simulation, including CMOS technology nodes (180nm, 90nm, 65nm, 45nm, 28nm) and standard cell libraries, ensuring simulation results reflect realistic process parameters.
Parametric Simulation and Corner Analysis
We conduct parametric sweeps over design variables, transistor sizing, bias currents, load capacitance, and run corner simulations (TT, FF, SS, FS, SF corners) to assess performance variation across process corners and temperature ranges.
Performance Metric Extraction
We extract all circuit performance metrics required for your research paper — gain, bandwidth, phase margin, slew rate, power consumption, offset voltage, noise figure, THD, SNDR, input/output range — and others relevant to your specific circuit type.
Layout Design in Cadence Virtuoso Layout Suite
For research requiring physical design, we create the full custom layout, following design rules, matching constraints, and shielding requirements, using the target technology's design rule deck.
Design Rule Check (DRC) and Layout vs. Schematic (LVS) Verification
We run DRC and LVS using Cadence Assura or Mentor Calibre and resolve all violations, ensuring layout correctness before parasitic extraction.
Parasitic Extraction and Post-Layout Simulation
We extract parasitic capacitances and resistances from the layout using Cadence Quantus or Calibre xRC and run post-layout simulation, comparing pre-layout and post-layout performance to demonstrate robustness.
Comparative Table Preparation
We compile all simulation results into performance comparison tables, benchmarking your proposed circuit against state-of-the-art designs from recent IEEE JSSC, TCAS, or Microelectronics Journal papers.
Specialized Modules
Sub-Services
Module 01
Analog IC Design and Simulation, Op-Amps, ADCs, PLLs
For research in operational amplifier design, data converters (ADC/DAC), phase-locked loops (PLL), bandgap references, and LDO regulators, we implement the circuit in Cadence Virtuoso, run complete SPICE analysis, and produce performance tables comparing gain, bandwidth, power, and figure-of-merit against published reference designs.
Module 02
CMOS Digital Circuit Design and Simulation
For VLSI research involving combinational and sequential logic design, standard cell-based implementation, and timing analysis, we design and simulate digital circuits in Cadence, verifying functionality through transient simulation and analysing power, delay, and area metrics at the schematic level.
Module 03
RF and Microwave Circuit Simulation in Cadence
For research in Low Noise Amplifiers (LNA), Power Amplifiers (PA), mixers, oscillators (VCO), and RF front-end circuits, we set up and run RF-specific simulations in Cadence Spectre RF, including S-parameter simulation, noise figure analysis, harmonic balance for nonlinear analysis, and envelope simulation for modulated signal testing.
Module 04
Mixed-Signal Circuit Design and Verification
For PhD research involving analog-to-digital interfacing, mixed-signal subsystems, or system-on-chip (SoC) blocks, we handle both the analog and digital schematic design, conduct mixed-signal co-simulation, and verify correct functionality across the analog-digital interface.
Module 05
Post-Layout Simulation and Performance Comparison
For research where your work must demonstrate post-layout robustness — a requirement of many IEEE JSSC and Microelectronics Journal papers — we complete the layout, run DRC and LVS, extract parasitics, and conduct post-layout simulation. We produce a performance comparison table with pre-layout results and the state-of-the-art reference designs your paper benchmarks against.
