Moving to Rev 2.0 Splits ,Coverage : 14%

Expected Completion data : 13th Feb

Changes are being pulled into  for C2K /GPS including major Clock plan changes and Digital filter coefficients changes.
 * C2K MODEM on Splits ,C2K Concurrencies ,Q6 Validation and FMAX Correlation, DCVS ,System Analysis(Q6,BUS,Memory) : New Features(720P Decode etc) ,Higher ARM9 Utilization, 768 MHz Validation ,HW Stability issues


 * Phase – I Completed Jan 19th: Coverage 94% . Only some performance issues are there


 * Overall standalone C2K ,UMTS looks OK : Can PASS SFN


 * GPS : Stability issues and some issues with PCS band (being debugged)Gimilshah (talk) 07:47, 28 January 2009 (UTC)

Validation for Raptor2 + Ahi75 to ensure it performs "same as" Raptor2 + Ahi80 is ongoing
 * Testing for Rev B and DC Loop is ongoing

Multimedia ASIC Verification
 * No Issues observed we can close this AI . Ahi75 has bee evaluated in terms of stability for these tests with no issues

QDSP6 FMAX and Vmin correlation:
 * Q6 validation as started on Rev 2.0 Splits.
 * Low DL throughput. ARM9 saturates during 7.2DL and 2.0UL. SMD and IST0 tasks seem to be the high ARM9 MIPS users. Verified the new HSDPA DL architecture and SMD optimizations STILL seeing no Improvement
 * Concurrent 720p and HSDPA data call causes frame drops and reduced HSDPA throughput. Issue might be with bus BW limitation. Also seen dropped frames with TV Out


 * Min MSMC3 tests have been done on Nominal and Fast parts at room and hot temperature.


 * Min MSMC3 for nominal parts during H264 video is seen to be around 1.20V. This is very close to the nominal setting of 1.23V and means that there is not much margin to decrease voltage when Q6 is running at 600MHz.

ISSUE with Sense Amps (Cache Settings ) :- Reset /Crash/Freeze seen on FAST
 * Correlation with PTE FMAX data is in progress and results will be released this week


 * As per RTP should not be;issue with Nominalpart

Issue with boot up at -30 C :Resolved Issues :-

Multimedia


 * Following are the major performance issues:
 * CR166447 – Low DL throughput. ARM9 saturates during 7.2DL and 2.0UL. SMD and IST0 tasks seem to be the high ARM9 MIPS users. This is expected to be fixed by the new HSDPA DL architecture and SMD optimizations, which might be released early next week.
 * Concurrent 720p and HSDPA data call causes frame drops and reduced HSDPA throughput. Issue might be with bus BW limitation.
 * 720p decode causes UI freeze when played in full-screen mode.
 * Waiting for new MEE release to test graphics/video/camera concurrencies
 * Low HSDPA DL throughput (around 5.4Mbps) with HD 720p decode.
 * CR166447 – Low DL throughput. ARM9 saturates during 7.2DL and 2.0UL
 * CR165378 - Video Graphics concurrency causes freeze. Video driver issue.
 * CR165375 – HW acc Video Graphics causes frame drops. SW acc video is fine.
 * CR165370 – Camera does not work with MEE. Blocking issue for camera video or graphics concurrency
 * Audio concurrencies not yet supported

 MODEM Issues - besides issues with Tx DAC,digital filter coefficient changes 

EV-DO : Degradation in Min Tx Output Power of 6 dB compared to other targets (We are at -54 dBm where as other targets we are at -60 dBm)

1x and DO Failing Spurious Emission:CR 158016 Reworked FFAs improved the same but still passing margin is negligible. Issue was found to be in mDSP FW. Working on validating the fix LOW Priority from RF Systems

CR:146496 - IS866A 321 FTC Demod AWGN is failing MPS

Issue is partially associated with LNA switch point, changing Ior pass MPS as expected
