Doxygen Filter for System Verilog 2.6.0 Released

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!

OVM 2.0.3 Release – Documentation Posted

December 30th, 2009

Posting this one a full release behind.  So this is for those of you that haven’t moved to the 2.1 release yet…

2.0.3 includes mostly bug fixes with a few performance improvements.  Changes include:

  • addition of messaging/logging macros to improve performance
  • promotion of convert2string() from ovm_transaction to ovm_object – replacing the do_sprint() method.
  • improved configuration performance
  • and a bunch of bug fixes

As usual – I have the updated OVM docs posted here:

If you find a bug in the doxygen documentation, then please let me know.

VMM 1.1.1 Released

This release came out a while back…  it’s an update to the 1.1.0 release – it adds support for the OVM/VMM interoperability library.  It looks like there are some bug fixes in there too.

As usual – documentation is posted here:

SystemVerilog Reset Transaction / Transactor Library Released

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.
