Foreword

Fundamentally, Chisel is a library of classes and functions representing the primitives necessary to express synchronous, digital circuits. A Chisel design is really a Scala program that generates a circuit as it executes.

Introduction

Chisel itself is not a big language. The basic constructs fit on one page and can be learned within a few days. Therefore, this book is not a big book, as well.

modulationReg是等腰三角的波形

pwm输入了这个等腰三角波形？

所以LED的亮度和时间长度有关系而不是幅度？

Example Designs

这一章开始就开始写的乱糟糟的了，或者说“跳跃性极大”。

A serial Port

这一节讲的很模糊，不像是一本入门书。

不讲讲信号是怎么编码的吗，不讲讲什么是baud rate吗？
