For the fifth edition, we have upgraded to the actual Chisel version 3.5.6 and Scala 2.13.
To make room for more advanced topics, I have removed the two appendicitis on
Chisel 2 and the PeekPokeTester. All projects that are actively maintained have finally
moved to Chisel 3, at least with the compatibility layer. The PeekPokeTester has been
deprecated with Chisel 3.5 and it is recommended to switch to ChiselTest.
If needed, those two chapters are available in the older versions of the Chisel book,
available as PDF at the web page for this book.
The fifth edition does not include major changes; it is a consolidation version.
We did a considerable proofreading for more clarity in writing. Chisel has added small convenience
features (e.g., ChiselEnum) that we cover in this edition.
We extended the processor chapter and updated the Leros code snippets
to the actual version of Leros.
