This marks BOOM version 2.2.2. The significant change is deprecation of boom-template, to switch to the unified Chipyard development platform, which incorporates flows for RTL simulation, FPGA simulation through FireSim, and physical design through HAMMER. The process to design custom BOOM-based SoCs is greatly simplified.

Chipyard usage is very similar to boom-template. See the Chipyard docs for details. https://chipyard.readthedocs.io/en/latest/

Chipyard is still in ALPHA,

Changes:

  • Integration of PNR head (#284)
  • RoCC accelerator support (#333, [#324], [#261], [#221])
  • Support for heterogeneous system (#309, [#278], [#271])
  • Allow non-power-of-2 core width (#314, [#316], [#312])
  • 4-cycle fetch with improved fetch buffer (#359, [#358], [#308])
  • Refactored, modularized rename and dispatch stages (#347, [#327], [#304])
  • Numerous QoR fixes (#344, [#343], [#342], [#341], [#340], [#335], [#334], [#330], [#329])
  • Fixes for MMIO loads and stores (#346, [#297])
