1.16.2
This is a minor bug fix release:
- Fixed a crash when an entity uses VHDL-2019 enhanced type generics and sub-elements of a port with a generic array type are associated individually (#1201).
- Fixed an issue where some
generatestatements were inaccessible from VHPI (#1213). - Several other minor bugs were resolved (#1202, #1204, #1212).
Special thank you to @bpadalino, @tmeissner, @Blebowski, @amb5l, @m42uko, @a-panella, @cmarqu, @albydnc, @johonkanen, and @augustofg for sponsoring me!

--preserve-case(#1195). - Fixed a crash when expression coverage is enabled and a port is associated with a non-static expression (#1194).
- Fixed a debug assertion failure when initialising an array with more than 2**32 elements (#1196).
- Fixed a crash when concatenating unconstrained arrays of arrays (#1199).

1.16.0
This is a major new release with the following changes:
- Added support for PSL
prev(),stable(),rose()andfell()built-in functions (#1135). - Signals can now be read and passed to subprograms during elaboration and the effective value is the default value associated with the signal. This behaviour is not defined by the LRM but matches all other simulators (#1144).
- MSYS2 binary packages are no longer provided with releases as these become out-of-date too quickly. Windows users should instead download the self-contained MSI package.
- The Ubuntu binary packages for releases now have predictable names without the git commit hash (#1131).
- Improved error messages when design units have circular dependencies or depend on obsolete design units (#1152).
- Toggle coverage count is displayed correctly for unreachable constant driven toggle bins and transitions from
Xare counted with--count-from-undefinedinstead of justU. - Added an experimental
--preserve-caseanalysis option to retain the original spelling of VHDL identifiers (#723). --ieee-warningsis now a global option and should be placed before the-rcommand. Passing it to the-rcommand is still supported but deprecated and may not take effect in some situations (#1151).- Fixed a crash when a partial association in a port map has a conversion function (#1161).
- Improved the formatting of the
--helpoutput. - The GitHub Action has been renamed from
nickg/setup-nvc-citonickg/setup-nvc, although the old name should redirect to the new. - A Docker image was added at
ghcr.io/nickg/nvc(#1165). - Unconstrained input ports can now be constrained by the result subtype of a conversion function (#1171).
- Type marks are now allowed in the prefix of selected names in relaxed mode (#1173).
- Added the
nvc.randomrandom number generation package and--seedargument for deterministic results. - Added support for PSL
unionoperator (from @Blebowski). - The implementation of concatenations has been reworked fixing several bugs (#1178).
- Added support for conditional force assignment (#1185).
- Access and file types are now supported in VHPI (#1192).
- Fixed a crash when open actual was used for formal parameter without default.
- Several other minor bugs were resolved (#1174, #1159, #1177, #1191, #1188).

1.15.2
This is a minor maintenance release fixing the following issues:

- External names can now be the target of concurrent signal assignment statements (#1156).
- Fixed a crash when packages are passed through multiple layers of generics.
- Fixed a crash when a record subtype has a partially constrained element (#1155).
- Fixed wrong result of VHDL-2019
std.env.file_pathwhen the source file was analysed using a relative path (#1162). - Fixed a crash when

1.15.0
This is a major new release with the following changes:
--loadis now a global option and should be placed before the-rcommand. This allows VHPI foreign subprograms to be called during elaboration (#988).- The
--per-filecoverage report option outputs code coverage reports for each source file instead of each instance (#823). - The new
--check-synthesisanalysis option warns when signals are missing from process sensitivity lists. - Fixed a crash when a generic subprogram is associated with
open(#1025). - Added a functional coverage API in
nvc.cover_pkgthat can be used by external frameworks such as OSVVM to define cover points. - Added
threshold-<value>option for coverage to set minimal count a coverage bin must reach to be reported as covered. - Added a warning for potential infinite loops in processes without sensitivity and lacking any wait statements (from @NikLeberg).
- Selected names can now be used to register value change callbacks with
vhpi_register_cb(#1045). - Removed the limit on the maximum number of parameters that can be passed to a VHDL subprogram (#1036).
- The new
--no-saveanalysis option parses and checks the input files but does not save the working library to disk. This is a replacement for the--syntaxtop-level command which is now deprecated. - The coverage database file name has changed to
<toplevel>.ncdbin the current working directory and this can now be customised with the new--cover-file=elaboration option. Attempts to access the old file name inside the library directory will be redirected to the new location, with a warning. - Partial association of ports with interface views now works correctly (#1074).
- Added support for PSL suffix implication, SERE repetition, and SERE fusion.
- Nested arrays more than two levels deep can now be dumped in FST format (#1071).
- Added support for package external names (#1072).
- Fixed parser hang for bit string literals (from @NikLeberg).
- Fixed a crash on an illegal package definition inside an interface.
- Comping the Vivado vendor libraries with
nvc --install vivadois now around 2x faster and analysing files with many dependencies is up to an order of magnitude faster (#1098). - The
--jitelaboration mode now works on Windows-on-Arm systems. vhpi_assertnow behaves the same as VHDLassertfor the purposes of determining the simulation exit code and early termination (#1060).- The
'driving_valueattribute now works correctly with record types. - Added basic support for
'instance_name,'path_nameand'simple_nameattributes of generate block labels (from @NikLeberg) (#1125). - Comments are now parsed correctly inside PSL directives (#1129).
- Updated to OSVVM 2024.11 and UVVM 2024.10.08 for
nvc --install. - Several other minor bugs were resolved (#1038, #1057, #1067. #1124).

1.14.2
This is a minor bug fix release with the following changes:
- Fixed a crash when
'last_valueis used with record types (#1043). - Fixed a crash when a process sensitivity list contains an external name and the process is elaborated before the object referenced by the name (#1062).
- Fixed parser hang for integers in scientific notation (from @NikLeberg).
- Fixed a platform detection issue that caused JIT code loading to fail on Apple silicon macOS (#1069).
- The
STD_INPUTandSTD_OUTPUTfiles can now be opened and closed multiple times (#1079). - Fixed a crash when a subtype is used for an aggregate element association range choice which associates an array slice (#1080).
- Several other minor bugs were resolved (#1038, #1055).

worklibrary alias and the working library has the same name as design unit being analysed (#991). - Added a check for illegal references to signal or variable external names inside pure functions (#1010).
- Added a check that the parameter of
'stableand other implicit signal attributes is a static expression (#1018). - Fixed an elaboration crash when an external name is passed to a procedure (#1029).
- Record subtype constraints can now be accessed over VHPI (#1035).

- The
-csub-command for coverage is deprecated and replaced with separate--cover-reportand--cover-mergecommands. See the manual for details. - The argument to the

--force-initcommand which was deprecated in the 1.7 release has been removed. - Coverage exclude files now support
foldcommand to merge coverage data from independent sub-hierarchies (from @Blebowski). - FSM state coverage bin renamed from

- External name elaboration order checks were overly strict (#964).
- Associating a signal with an
outorinoutparameter in a procedure that is not within a process now produces an analysis error rather than crashing at runtime (#965). - The
