Learn CHISEL-HDL with Real Code Examples

Install Java and Scala runtime

Set up SBT (Scala Build Tool) environment

Clone Chisel repository or add it as an SBT dependency

Verify installation by building sample Chisel projects

Run ChiselTest simulations for functional verification

Install Java and Scala runtime

Set up SBT build tool

Add Chisel dependencies in build.sbt

Verify project structure with sample Chisel modules

Run example simulations using ChiselTest

build.sbt - SBT project config

src/main/scala - Chisel modules

src/test/scala - ChiselTest files

target/ - generated Verilog and compiled classes

resources/ - auxiliary files

sbt run - compile and run Chisel project

sbt test - run ChiselTest simulations

sbt clean - clean project artifacts

GenerateVerilog() - invoke FIRRTL Verilog generation

sbt runMain <MainClass> - run specific hardware generator

UTF-8 support in Chisel code

Comments and documentation can be localized

Works for multi-language research and teaching

Simulation output compatible with international tools

Parameterization supports scalable global designs

Runs on Linux, Windows, macOS for development

Open-source with BSD license

Extensive documentation and tutorials available

Active academic and research community

Accessible to developers familiar with Scala and digital design

No native UI; output via simulation logs

Integration with waveform viewers like GTKWave or Verilator

Visualization handled externally in testbenches

Scala REPL can be used for interactive testing

Optional integration with IDEs for syntax highlighting

Registers hold sequential state

Wires represent combinational signals

Modules encapsulate internal state

Bundles and Vecs manage grouped signals

Simulation tracks signal propagation across cycles

Signals carry data across modules

Registers store persistent values per clock cycle

Vecs and Bundles structure multi-bit data

Input/output ports define module interface

Simulation logs track data evolution for verification
