2-input AND Gate — Chisel-hdl Code
Implement a 2-input AND gate in Chisel.
import chisel3._
class AndGate extends Module {
val io = IO(new Bundle {
val A = Input(Bool())
val B = Input(Bool())
val Y = Output(Bool())
})
io.Y := io.A & io.B
}
object AndGate extends App {
chisel3.Driver.execute(args, () => new AndGate)
}Chisel-hdl Language Guide
Chisel (Constructing Hardware in a Scala Embedded Language) is a hardware description language embedded in Scala. It provides a modern, object-oriented approach to designing digital circuits and generating synthesizable Verilog for FPGAs and ASICs.
Primary Use Cases
- ▸Designing parameterizable digital modules
- ▸Creating reusable hardware generators for CPUs and peripherals
- ▸Rapid prototyping for FPGA development
- ▸Integration with simulation and verification frameworks
- ▸Generating synthesizable Verilog for ASIC and FPGA flows
Notable Features
- ▸Embedded DSL in Scala for hardware design
- ▸Supports parameterized and modular generators
- ▸Strong type system with compile-time checks
- ▸Integrated with FIRRTL for intermediate representation
- ▸Testing and simulation tools for functional verification
Origin & Creator
Developed at UC Berkeley by the Berkeley Architecture Research group to modernize hardware design with high-level programming abstractions, leveraging Scala’s features.
Industrial Note
Essential for hardware architects and FPGA/ASIC designers who want reusable, parameterizable, and maintainable RTL generators, reducing manual Verilog coding and improving design productivity.
