removed the concept of extra history bits from gshare_fa.
added history_bits as a new parameter to indicate the size of bits used from the ghr for indexing.
reduced tick resolution in test_soc.
updated the 2 bit counter increment scheme to account for hysterisis bit separately.
updated the gshare has function for improved collisions.
updated repomanager to 1.2.0.
merged usermanual and datahseet into a single doc.
added chromite specific device-tree-string.
documentation of the pipeline added.
made the size of the test-soc BRAM memory configurable through YAML.
the core now re-aligns data and write-strobes on the AXI4 write channel for io requests.
renamed the everilated binary from “out” to “chromite_core”
added a local boot-code and respective build files
added missing ‘ifdef pmp’ in ccore.bsv
minor style fixes in TbSoc
updated ci for docs build at pre-merge
- [0.9.1] - 2020-05-01
parallel build using bluetcl is enabled
remove re-alignment of bytes in ccore for I$ and D$ reads. This now is handled within the caches
bumped version of the caches
gitignore updated
fixed and cleaned up the interrupt and delegation logic
adding pre-requisite checks in configure
default.yaml is picked up as default if no argument given to -ispec
split interface of seip and meip. Both can now be driven by plic independently. Also led to removal of unwanted attributes.
snapshot the c-class with changes in mostly the top-level modules and scripts to accommodate for incore developed IPs and fabrics.
fixed reset logic handling in ccore.bsv to support reset by debugger.
updated SoC to decouple debug related logic into a separate module. This now allows for easy reset control.
