This changelog follows the format defined here: https://keepachangelog.com/en/1.0.0/

[1.10.0] - 2023-6-16

Adds superscalar in-order core, prefetchers, architectural checkpointing, examples for custom-chiptop/tapeout-chip/flat-chiptop. FireSim bumped with new local FPGA support: Xilinx VCU118 (w/XDMA), Xilinx Alveo U250/U280 (w/XDMA, in addition to previous Vitis support), RHSResearch NiteFury II (w/XDMA). FireSim now also supports Xcelium for metasims.

[1.3.0] - 2020-05-31

A more detailed account of everything included is included in the dev to master PR for this release: ucb-bar#500

Added

  • A new Top-level module, ChipTop, has been created. ChipTop instantiates a "system" module specified by BuildSystem. (#480)
  • A new BuildSystem key has been added, which by default builds DigitalTop (#480)
  • The IOBinders API has changed. IOBinders are now called inside of ChipTop and return a tuple3 of (IO ports, IO cells, harness functions). The harness functions are now called inside the TestHarness (this is analogous to the previous IOBinder functions). (#480)
  • IO cell models have been included in ChipTop. These can be replaced with real IO cells for tapeout, or used as-is for simulation. (#480)
  • CI now checks documentation changes (#485)
  • Support FireSim multi-clock (#468)
  • Allows make variables to be injected into build system (#499)
  • Various documentation/comment updates (#511,#517,#518,#537,#533,#542,#570,#569)
  • DSPTools documentation and example (#457, #568)
  • Support for no UART configs (#536)
  • Assemble firrtl-test.jar (#551)
  • Add SPI flash configurations (#546)

  • NVDLA integration (#505, #559, #580)
  • Add support for Hammer Sim (#512,#581,#580,#582)

Changed

  • Bump FireSim to version 1.10 (#574,#586)
  • Bump BOOM to version 3.0 (#523, #574,#580)
  • Bump Gemmini to version 0.3 (#575, #579)

  • Bump FireMarshal to version 1.9.0 (#574)
  • Chisel 3.3 and FIRRTL 1.3 (#503,#544)
  • BuildTop now builds a ChipTop dut module in the TestHarness by default (#480)
  • The default for the TOP make variable is now ChipTop (was Top) (#480)
  • Top has been renamed to DigitalTop (#480)
  • Bump libgloss (#508, #516, #580)
  • The default version of Verilator has changed to v4.034 (#547). Since this release adds enhanced support for Verilog timescales, the build detects if Verilator v4.034 or newer is visible in the build environment and sets default timescale flags appropriately.
  • Use Scalatests for FireSim CI (#528)
  • Cleanup Ariane pre-processing (#505)
  • Modify Issue Template to be more explicit (#557)

[1.0.0] - 2019-10-19

Added

  • This repository used to be "project-template", a template for Chisel-based projects. Through tighter integration of multiple projects from the Berkeley Architecture Research group at UC Berkeley, this repository is re-released as Chipyard - a framework for agile hardware development of RISC-V based Systems-on-Chip.
