|
2021-10-03 23:00:59 +02:00
|
|
|

|
### Other Enhancements
|
|
|
|
|

approximate source location information to help locate the error

procedural assignment

## v0.0.9
|
2021-08-08 05:11:35 +02:00

### Breaking Changes
|
|
|
|
|
|
2021-08-10 06:10:29 +02:00
|
|
|
* Unsized number literals exceeding the maximum width of 32 bits (e.g.,
|
2021-09-22 04:01:21 +02:00
|
|
|
`'h1_ffff_ffff`, `4294967296`) are now truncated and produce a warning, rather
|
2021-08-10 06:10:29 +02:00
|
|
|
than being silently extended
|
|
|
|
|
* Support for unsized number literals exceeding the standard-imposed 32-bit
|
|
|
|
|
limit can be re-enabled with `--oversized-numbers`
|
2021-09-22 04:01:21 +02:00
|
|
|
* Input source files are now decoded as UTF-8 on all platforms, with transcoding
|
|
|
|
|
failures tolerated, enabling reading files encoded using other ASCII supersets
|
|
|
|
|
(e.g., Latin-1)
|
|
|
|
|
|
|
|
|
|
### New Features
|
|
|
|
|
|
|
|
|
|
* Added support for non-ANSI style port declarations where the port declaration
|
|
|
|
|
is separate from the corresponding net or variable declaration
|
|
|
|
|
* Added support for typed value parameters declared in parameter port lists
|
|
|
|
|
without explicitly providing a leading `parameter` or `localparam` marker
|
|
|
|
|
* Added support for tasks and functions with implicit port directions
|
|
|
|
|
* Added support for parameters which use a type-of as the data type
|
|
|
|
|
* Added support for bare delay controls with real number delays
|
|
|
|
|
* Added support for deferred immediate assertions
|
|
|
|
|
|
|
|
|
|
### Other Enhancements
|
|
|
|
|
|
|
|
|
|
* Explicitly-sized number literals with non-zero bits exceeding the given width
|
|
|
|
|
(e.g., `1'b11`, `3'sd8`, `2'o7`) are now truncated and produce a warning,
|
|
|
|
|
rather than yielding a cryptic error
|
2021-08-10 06:10:29 +02:00
|
|
|
* Number literals with leading zeroes which extend beyond the width of the
|
|
|
|
|
literal (e.g., `1'b01`, `'h0_FFFF_FFFF`) now produce a warning
|
2021-08-08 05:11:35 +02:00
|
|
|
* Non-positive integer size casts are now detected and forbidden
|
|
|
|
|
* Negative indices in struct pattern literals are now detected and forbidden
|
2021-09-22 04:01:21 +02:00
|
|
|
* Escaped vendor block comments in macro bodies are now tolerated
|
2021-09-28 05:51:53 +02:00
|
|
|
* Illegal bit-selects and part-selects of scalar struct fields are now detected
|
|
|
|
|
and forbidden, rather than yielding an internal assertion failure
|

### Bug Fixes
|
|
|
|
|
|
|
|
|
|
* Fixed parsing of sized ports with implicit directions
|
|
|
|
|
* Fixed flattening of arrays used in nested ternary expressions
|
|
|
|
|
* Fixed preprocessing of line comments which are neither preceded nor followed
|
|
|
|
|
by whitespace except for the newline which terminates the comment
|
|
|
|
|
* Fixed parsing of alternate spacings of `@(*)`
|
|
|
|
|
* Fixed conversion of interface-based typedefs when used with explicit modports,
|
2021-09-19 03:46:32 +02:00
|
|
|
unpacked arrays, or in designs with multi-dimensional instances
|
2021-09-22 04:01:21 +02:00
|
|
|
* Fixed conversion of module-scoped references to modports
|
|

|
* Fixed conversion of references to modports nested within types in expressions
|
2021-09-24 18:36:49 +02:00
|
|
|
* Fixed assertion removal in verbose mode causing orphaned statements
