Doxygen Filter for System Verilog 2.6.0 Released

Monday, January 4th, 2010

A new filter release!

Finally!  Released what has been sitting in trunk for months now…

This release includes:

  • bugfix: SystemVerilog interfaces with parameters not supported (#47)
  • change: improved routine for processing parameterizations

You can pick up the release from the downloads page here:

http://intelligentdv.com/downloads/index.html#doxygentools

Or – you can grab it directly from the subversion repository with your svn client (or using the WebSVN site here).

TIP! These blog announcements (like this one) often lag the actual release by several weeks…  so I recommend subscribing to the RSS feed for the Doxygen tags on the WebSVN site to keep up-to-date.

A Reminder: the doxygen filter is not a grammar — it, like the doxygen tool, is a lexical parser. So – you will find bugs.  And when you do – please file them to the bug tracker here:

http://intelligentdv.com/bugs/

Your tickets in the tracker are what pushes the filter improvements.

-improved!

SystemVerilog Reset Transaction / Transactor Library Released

Wednesday, August 19th, 2009

I’ve created and released a randomizable SystemVerilog reset transaction / transactor library. Not only is this library useful for those simply looking for a randomized mechanism for sending reset(s) to a device under test (DUT), it is also useful for those of you looking to see how to build a transaction based bus functional model / monitor in both a generic and VMM 1.1 style. The generic models are wrapped with their VMM counterparts and are tested using a VMM environment and signal layer.

Shows how to:

  • build a modern randomized SystemVerilog verification component / transaction in a generic fashion
  • integrate a generic transaction / component into the VMM
  • write a VMM transaction / transactor driver / transactor monitor
  • build a VMM environment and signal layer
  • connect a DUT to a class based testbench using interfaces with modport, clocking blocks and virtual interfaces
  • use SystemVerilog constraints to get a desired result
  • implement functional coverage
  • use VMM callbacks to collect functional coverage
  • create (and run) tests in the VMM style (vmm_test) – by instantiating and constraining the environment

Can be used to:

  • drive one (or more) active high or low reset(s)
  • drive a sync/async assert/deassert reset
  • drive reset for a specific or random range duration
  • assert / deassert asynchronously randomly within the clock period
  • monitor existing reset(s) for coverage
  • can be driven with transactions or with direct method calls of the bfm methods

All of the SystemVerilog library source code including the code required to document and run the environment are available to download here:

http://www.intelligentdv.com/downloads/index.html#svreset

The library is fully documented with doxygen and that documentation is available here:

http://www.intelligentdv.com/documents/index.html#resetdox

The complete details of what the library includes are after the break.

  • bugfix: protected keyword does not play well with multi-line enums and member variables (#45)
  • bugfix: import package should be ignored (#40)
  • feature: add support for SV Packages (#20)
  • workaround: Does not handle nested OVM macros (doxygen issue) (#43)
  • change: comments are no longer filtered from source (doxyfile delta change)
  • change: added language switch for sv/svh extension — C++

You can pick up the release from the downloads page here:

SystemVerilog Syntax Files Release 3.0.1 – 1800-2009 and GeSHi

Tuesday, July 21st, 2009

A new release of the syntax files set is now available. All of the syntax files have been updated to reflect recent changes to the SystemVerilog IEEE 1800 standard (up to the draft 1800-2009 release).

This includes syntax files for:
- Kate (KDE Linux Editor)
- Crimson (Windows Editor)
- SciTE (Windows Editor – with syntax color RTF copy support)
and
- GeSHi (PHP based Syntax Highlighter)

So what’s GeSHi? Awesomeness!

GeSHi is how I have color coded SystemVerilog code posted on my blog (using WordPress with the WP-Syntax plugin) — like here in this blog post.

And GeSHi is how I have color coded code posted in my WebSVN repository – like here in the SVtimers repository.

Yeah – GeSHi is pretty cool.
I’ve sent my syntax file to the GeSHi team – hopefully they’ll accept it in their release.

You can download this release here:

A new release to the SV simulation timers is now available!

This release includes

  • fix for potential race condition on restart [#37]
  • fix for issue with timescale in the tests [#36]
  • proper use of ID for OVM console log reporting

You can see the doxygen documentation for this release here:

http://intelligentdv.com/documents/index.html#timersdox

Note that the doxygen documentation for the SV Timers includes comments on how to use the timers in base, OVM, and VMM forms.

And you can download the release here:
