Technology Overview

VLSI Design Expertise

VLSI (Very Large Scale Integration) design is one of the most specialized and demanding disciplines in engineering — requiring expertise in hardware description languages, EDA tools, timing constraints, physical design rules and the complex interplay between digital design and silicon physics.

SoftRoute's VLSI team provides end-to-end IC design support — from RTL coding in Verilog/VHDL through functional verification, synthesis, static timing analysis and physical design. We serve semiconductor companies, fabless design houses, research institutions and embedded systems teams that need experienced VLSI engineers without the overhead of full-time hiring.

VLSI Design Service Capabilities

End-to-end VLSI Design capabilities — from initial design and implementation through performance optimization and ongoing managed support.

RTL Design (Verilog / VHDL)

Register-Transfer Level design of digital circuits — ALUs, processors, controllers, state machines and complex datapaths — coded in Verilog, SystemVerilog or VHDL following industry coding guidelines.

Functional Verification

Comprehensive testbench development using SystemVerilog UVM — constrained random stimulus, functional coverage models, assertion-based verification and regression testing for high-confidence sign-off.

Logic Synthesis & Optimization

RTL-to-gate netlist synthesis using Synopsys Design Compiler or Cadence Genus — timing constraint development, area optimization, power reduction and technology mapping for target process nodes.

Physical Design

Floorplanning, power planning, placement, clock tree synthesis (CTS), routing and design rule checking (DRC/LVS) — physical implementation from netlist to GDSII using Cadence Innovus or Synopsys ICC2.

Static Timing Analysis

Setup/hold timing analysis, multi-corner multi-mode (MCMM) analysis, timing closure and ECO implementation using Synopsys PrimeTime — ensuring robust silicon performance across PVT corners.

FPGA Prototyping

Rapid FPGA-based prototyping of ASIC designs on Xilinx/Altera platforms — enabling early software development, hardware validation and design exploration before committing to silicon.

FAQ

Common Questions

We work with the major EDA suites: Synopsys (Design Compiler, VCS, PrimeTime, ICC2), Cadence (Innovus, Xcelium, Genus, Virtuoso), Mentor/Siemens (Questa, Calibre) and Xilinx/Intel Quartus for FPGA. Tool selection is based on your existing licenses and project requirements.
Both. For ASICs, we handle the full RTL-to-GDSII flow for tape-out. For FPGAs, we do RTL development, constraint creation, implementation and bitfile generation. We also do ASIC prototyping on FPGA platforms to enable early software development and hardware validation.
We have experience from 180nm legacy nodes down to 5nm advanced nodes. Process node selection, design rule awareness and tool calibration differ significantly across nodes — we ensure our team is familiar with the specific PDK and design rules for your target foundry.
Yes. SoC verification is a specialty — we develop modular UVM testbenches for individual IP blocks and integrated SoC-level verification environments. We also set up coverage closure plans, regression infrastructure and formal verification for critical control logic.
