后续开启RISC-V开发相关内容。

 

RISC-V开发推荐使用Chisel编程语言。Chisel即Constructing Hardware in a Scala Embedded Language：

Chisel is an open-source hardware construction language developed at UC Berkeley that supports advanced hardware design using highly parameterized generators and layered domain-specific hardware languages.

• Hardware construction language (not C to Gates)

• Embedded in the Scala programming language

• Algebraic construction and wiring

• Abstract data types and interfaces

• Bulk connections

• Hierarchical + object oriented + functional construction

• Highly parameterizable using metaprogramming in Scala

• Supports layering of domain specific languages

• Sizeable standard library including floating-point units

• Multiple clock domains

• Generates low-level Verilog designed to pass on to standard ASIC or FPGA tools

• Open source on github with modified BSD license

• Complete set of docs

• Growing community of adopters

 

Chisel基于Scala，所以Chisel开发使用Scala开发环境，项目构建使用sbt。

Scala是基于Java虚拟机的语言。Java开发IDE首选Intellj IDEA。但是Intellj IDEA不是原生支持Scala，需要安装插件。

 

安装插件的方法可以网上搜一搜，这里介绍一个比较简单的方法：

1. 找到一个Scala源码文件，使用IDEA打开：

​​

 

2. 根据提示，点击安装插件即开始下载安装（国外网站，中国人需要耐心等待一会儿），安装完成之后重启即可。

Linux下Scala开发环境的安装，网上有教程。

 

网站上提供了很多参考资料。
