Chisel Versions

Since Chisel is relatively a new language, it is still evolving and changing. There are 3 versions of Chisel at the moment:

• Chisel 1 - not used anymore, only mentioned for historical reasons.
• Chisel 2 - still used in some parts of our designs.
• Chisel 3 - the newest version.

The latest version of Chisel language can be found here: https://chisel.eecs.berkeley.edu/releases.html

The differences between Chisel 2 and Chisel 3 are well described here: https://github.com/freechipsproject/chisel3/wiki/Chisel3-vs-Chisel2
