  Package structure

  The chisel3 package presents the public API of Chisel. It contains the concrete core types UInt, SInt, Bool, Clock, and Reg, the abstract types Bits, Aggregate, and Data, and the aggregate types Bundle and Vec.

  The Chisel package is a compatibility layer that attempts to provide chisel2 compatibility in chisel3.

  Utility objects and methods are found in the util package.

  The testers package defines the basic interface for chisel testers.

  ChiselTest Compatibility Layer for Chisel 7

  ChiselTest Compatibility Layer for Chisel 7

  This package provides a drop-in replacement for the ChiselTest library that was removed in Chisel 7. It preserves the familiar ChiselTest API while delegating to Chisel 7's ChiselSim underneath.

  Usage:

  import chiseltest._
  import org.scalatest.flatspec.AnyFlatSpec
  
  class MyTest extends AnyFlatSpec with ChiselScalatestTester {
    it should "work" in {
      test(new MyModule) { dut =>
        dut.io.in.poke(42.U)
        dut.clock.step()
        dut.io.out.expect(42.U)
      }
    }
  }

  Key Components: - testableData, testableUInt, testableBoolExt: Implicit conversions for poke/peek/expect - testableClock: Clock stepping and control - DecoupledIOOps: Utilities for Decoupled interface testing - ChiselScalatestTester: ScalaTest integration trait

  See README.md for detailed documentation.

  Formal verification is currently unsupported in this compatibility layer. Any usage should fail at compile time to avoid vacuously passing tests.
