v1.13.0

Added

• Added exponential backoff window module
• Added parametric Galois LFSR module with optional whitening feature
• Added cf_math_pkg: Constant Function implementations of mathematical functions for HDL elaboration

Changed

• Parametric payload data type for rr_arb_tree

Deprecated

v1.11.0

Changes since 1.10

1.11.0 - 2019-03-20

Added

• Add stream fork
• Add fall-through register
• Add stream filter
• Add ID queue

Changed

• sync_wedge use existing synchronizer. This defines a single place where a tech-specific synchronizer can be defined.

Fixed

• Fix FIFO push and pop signals in stream_register to observe interface prerequisites.
• In fifo_v3, fix data output when pushing into empty fall-through FIFO. Previously, the data
  output of an empty fall-through FIFO with data at its input (and push_i=1) depended on
  pop_i: When pop_i=0, old, invalid data were visible at the output (even though empty_o=0,
  indicating that the data output is valid). Only when pop_i=1, the data from the input fell
  through. One consequence of this bug was that data_o of the fall_through_register could change
  while valid_o=1, violating the basic stream specification.

v1.10.0

Changes since v1.9.0

Added

• Add fifo_v3 with generic fill count
• Add 16 bit LFSR
• Add stream delayer
• Add stream arbiter
• Add register macros for RTL
• Add shift register

Changed

• Make number of registers of rstgen_bypass a parameter.

Fixed

• Fix valid_i and grant_i guarantees in generic_fifo for backward compatibility.
• LZC: Synthesis of streaming operators in ternary operators
• Add missing entry for popcount to Bender.yml.
• Add default values for parameters to improve compatibility with Synopsys DC and Vivado.
