Sigasi Studio 3.5 brings full support for the SystemVerilog language, a frequently asked VHDL quickfix, a better State Machine Viewer and much more.
Sigasi Studio 3.5 finally brings full SystemVerilog support. Providing good editing and navigation support for the complex and colossal SystemVerilog language was an interesting technical challenge. We are proud to present our solution, that is both powerful and requires only very limited configuration.
In addition to the SystemVerilog source files, Sigasi Studio only needs to know the include paths. Based on this information, Sigasi Studio automatically figures out in which order to analyze the files.
Sigasi Studio processes the code in a predictable order and keeps track of the preprocessor state. This allows us to offer full support for both SystemVerilog source files and include files. With Sigasi Studio, you can edit include files as if they were included in a SystemVerilog file.
- Syntax error feedback: All valid SystemVerilog-2012 code should be accepted as valid code. Syntax errors are flagged while you type.
This works for both SystemVerilog and Include files, and for both Preprocessor and real SystemVerilog code.
- Preprocessor: Sigasi Studio has a complete preprocessor. You can preview the text expansion with a hover or in the Preprocessor View.
- Include paths can be set with a quickfix, or by right clicking a project, selecting Properties, and opening the Verilog Preprocessor page.
- Semantic highlighting, Open Declaration and Find References
- Autocomplete (Ctrl+Space):
- Syntax: autocomplete for keywords and identifiers
- Fixed Templates: these templates can be modified
- Smart Templates: module instantiations
- Preprocessor directives
- Integration with an external compiler (Riviera-Pro, ModelSim, NCsim, OneSpin).
- We have a first version of SystemVerilog formatting. Clean Indentation (Ctrl+Shift+F) formats the entire file in the editor.
- Rename refactoring
- Libraries View gives an overview of all design units in your project.
Getting started with Sigasi Studio on your own projects is easy. The blog post “How to setup a SystemVerilog project in Sigasi Studio”, describes how easy it is.
We gave the State Machine Viewer a refreshing update. We improved the looks. We have real bubbles now and transitions (edges) no longer overlap with states. If a design file has multiple state machines, we now display all state machines next to each other (i.e. no more tabs).
If your state machine uses simple
if-conditions for transitions, the conditions will be displayed on the transistions (if you enable the “Aa”-button).
[Only for VHDL] Quickfix all undeclared signals in a port map. This was the number one feature request for our VHDL editor. You can now declare all signals in a port map (and all constants in a generic map) in a single action
Improved Libraries View:
- Mixed language support
- Added action to Set toplevel
Open Design Unit dialog (Ctrl+Shift+D): We added an extra action to quickly open a (VHDL or SystemVerilog) design unit in an editor: hit Ctrl+Shift+D (or via Navigate > Open Design unit…), and type a pattern that matches the design unit name you’re looking for
[Only for VHDL] Hyperlink from Entity to its architectures. There has always been an easy way to navigate from an architecture to its entity, by Ctrl+clicking (Open Declaration) the entity name. You can now also easily navigate in the other direction with Ctrl+click. If an entity has multiple architectures, they will all be listed in a drop down menu
[Only for VHDL] Better autocomplete for
[Only for VHDL] Offer “Declare variable” quickfix for procedure parameters inside processes
[Sigasi Studio XL ] Better validations for
[Sigasi Studio XL ] keyword autocomplete now respects the uppercase/lowercase formatting settings
[Sigasi Studio XL Doc ] The block diagram view now displays the component name of component instantiations
We updated the Eclipse Xtext dependency to
As expected the old formatter had some untested “features”, that the new formatter in Sigasi 3.4 didn’t have.
This release brings many improvements to make the new formatter return the same results.
Thanks a lot for all the feedback!
