Type of Improvement

  • Bugfix

Desired Merge Strategy

  • Squash

Release Notes

Previously, the user-specified (or unspecified minimum width) of the literal would be used in some operations like concatenation. For literal values that are too-wide, they will now truncate to the correct width. This will become a warning (then later an error) in newer major versions of Chisel.

* Fix widths for literal values in Bundle literals

Previously, the user-specified (or unspecified minimum width) of the
literal would be used in some operations like concatenation.

* Implicitly truncate too-wide literals in Bundle literals

This is to fix a bug in concatenation without breaking things relying on
implicit truncation. This will be a warning in newer versions of Chisel.

(cherry picked from commit 3939e57)
Also move waivers from files to build.sbt.
