A special thank you to Brian Padalino and T. Meissner for sponsoring me!
- Breaking change: In-tree builds are no longer supported: use a separate build directory instead.
- Breaking change: The
--force-initcommand is deprecated and has no effect.
- Added support for VHDL-2008 type generics on packages and entities.
- Diagnostic messages have been enhanced with more contextual information.
- Added support for record element constraints and record fields with unconstrained array types.
- Alias of multidimensional array allowed in VHDL-2008 mode.
- Implemented VHDL-2008 rules for aggregates with slices.
- VHPI is now always enabled at build time and the
--enable-vhpiconfigure option has no effect.
- Arithmetic operations that overflow the underlying machine type now produce an error (#101).
- Added support for VHDL-2008 force/release assignments.
- Basic support for external names in VHDL-2008.
- Matching case
case?statements are supported in VHDL-2008 mode.
- Fixed several bugs in the implementation of guarded signals.
- Implemented VHDL-2008 rules for generic visibility.
- Shared variable declaration permitted in entity declaration.
- Case expression no longer requires a locally static subtype in VHDL-2008 mode (#460).
- The VHDL heap is now garbage collected as required by VHDL-2019 and the
deallocateoperator has no effect other than setting the access to
- A new global option
-Hspecifies the size of the simulation heap and defaults to 16 megabytes.
- Concurrent procedure call allowed in entity statement part.
- Added support for
'ELEMENTattributes in VHDL-2008.
- The new top-level
--initcommand creates a new empty library directory.
-aanalysis command now reads from the standard input if the file name is
- Added support for array element constraints in VHDL-2008.
--prefer-explicitanalysis option which was deprecated before the 1.0 release has been removed.
- A new
--relaxedanalysis option enables “relaxed rules” mode. This has the same effect as enabling all the existing
--relax=options. However some constructs will still produce warnings.
--relax=analysis option is deprecated and is now equivalent to passing
--relaxed. The individual options are ignored.
- Added support for generic subprograms in VHDL-2008.
- New command
--installallows easy installation of common third-party packages such as OSVVM and UVVM.
- Identifiers in waveform dumps are now in lower case instead of upper case.
- The function
NVC.SIM_PKGcan be used to query the current delta cycle number.
