NetFPGA release note — 3.0.0_pre1 package

Release date

Aug 12, 2011

Major changes since the 2.2.0 release

This update introduces the following major features and changes:

• New Python-based verification infrastructure (see Verification)

Minor changes introduced in this update include:

• Removed unused modules from project.xml for all reference projects

Upgrading from the 2.2.0 release

Projects designed for the 2.2.0 release should work unmodified with the 3.0.0_pre1 release. It is recommended but not required that tests be rewritten to use the new verification infrastructure.

Full change log

Improvements:

• Verification infrastructure -- rewritten, Python-based
  • unified: run same tests in simulation and on hardware
  • reduces the need to specify explicit delays in test code
  • barriers: enables tests to be partitioned into sections in which code preceding a barrier must complete before proceeding past barrier
    Use case:

1. 1. 1. send and expect a number of packets,
      2. read registers only after all packets have been received

• • pcap: standard-format pcap files are generated for all tests run in hardware
  • random seed: can specify the random seed to use when running tests, allowing random data to be reproduced identically across runs
  • legacy mode: run existing tests without rewriting
• project XML:
  • remove unused strip_headers module from all projects

Bug fixes:

• register system:
  • fix width calculation bug in compound types
