--- Comment #1 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
TODO fill out toplevel milestones for the Wishbone proposal,
ready for the MoU, add budgets for each milestone.

# Specfication Improvements
Improve the Wishbone B4 Specification to add streaming capability, comparable
to AXI4-Stream, and feed the improvements back into the current stewardship for
next Wishbone release.

Budget: 2.000 EUR

# Verification Models
Design Reference Implementations in nmigen and (System-)Verilog, Bus Function
Models and other functionality in SystemVerilog for verification with full unit
tests aiming best code coverage.

Budget: 6.230 EUR

# Reference Implementation / Demonstrator
Use some of the Libre RISC-V SoC peripherals as a test platform and
demonstrator (I2S Audio Streaming) for the proposed standard modifications.

Budget: 1.350 EUR

# Traveling Expenses
Traveling expenses for presenting the Wishbone improvements to the RISC-V
community once at the annual ORConf in 2020.

Budget: 650 EUR

# Special Outgoings
Budget for additional, unpredictable efforts - e.g. literature research or
other traveling expenses.

Estimated with 7 % of the whole sum.

Budget: 770 EUR

# Additional peripherals
Seek out existing (non-streaming) Wishbone Master
and Slave Bus implementations (or implement them if necessary), provide
formal proof unit tests of their correctness, and add additional example

Budget: 12500 EUR
