4. Gary Varner, Belle II Directors Review (Pre CD-2/3)
WBS 1.03 Scope (2)
Firmware for real-time ASIC operation and data flow control and monitoring
FPGA/DSP microcoding for waveform data reduction
Documentation and support of ASICs and readout modules

5. Performance Requirements
Operate within the Belle II Trigger and Data Acquisition specifications
Meet the detailed timing and signal processing specifications for the iTOP and KLM sub-detectors
Fabricate using commodity components or processes with high yield and reliability assembly houses
Verify component and integrated module radiation tolerance for the background environment expected

Cost Basis of Estimate
Reasonable Cost Range
Make up of cost estimate
54% of total cost is subcontract of ASIC and circuit board fabrication and assembly
Competitive (commodity) quotes received for all components and assemblies
Engineering labor associated with prototype testing and final acceptance testing
Maturity of the estimate
Majority of remaining cost (67%) is commodity components or processes
Remaining estimate based on engineering estimate for development of calibration system, testing, and interface on mechanical system and actual cost from prototype articles.

10. Identified Project Risks
One high risk remains
Gary Varner and team in Hawaii are overcommitted and cannot complete all assigned scope on schedule.
Mitigation has been to transfer electronics development and testing scope to other institutions (IU, PNNL, WSU, VT, USC)
16-17 January 2013

11. Technical Risk Assesment
Performance of switched capacitor array waveform sampling has been well established in various experiments (ANITA, MUEGAMMA)
ASICs fabricated in high-volume, commodity IC vendor lines and are low risk
Module fabrication and QA/QC procedures are industry standard processes and low risk
Concurrent ASIC development cycles increase risk of delays due to design multi-tasking
Mitigate by having more stringent submission reviews with additional external experts
Further reduce stress on design engineering resources by increasing pool of qualified test and evaluation engineering talent

Conclusion
Scope of WBS well understood
Evidence – Performance achieved in beam and bench tests
Final opto-electro-mechanical configuration
Integration with existing Belle II DAQ infrastructure
Costs are known and fit within funding profile
Evidence – Costs defined by bid/vendor quote/similar work
Fits funding profile
Ready for CD-2 and (conditional) CD-3 pending success of recently submitted ASICs
