Spade 0.4.0

A hardware description language inspired by modern software languages.

Changes in 0.4.0:

Added

• Support initial values for registers
• Allow writing units that don't return a value.

Fixed

• Re-add missing requirement for the first argument of a pipeline to be a clock
• Fix panic on method calls in let bindings.
• Re-add working VCD translation. It now also translates more values
• Make generated code compile out of the box with verilator
• Fix code generation bug when matching two variant enums

Changed

• Rename wal_suffix attribute to wal_traceable. It now defaults to the struct name as a suffix, but can override that using the suffix parameter to the attribute.
• Add a new #[wal_suffix] attribute which emits a copy of the marked signal with a specific suffix. Can also be applied to units to add #[wal_suffix] to all inputs.
• Improve the error messages for positional arguments.

Removed

• Remove type dump file. This information was redundant and can be recovered from CompilerState instead
