Pin Level Functions • Members • Sirinvas, Karen, Nicco, Prashant • Scope: • Define CTL construct to describe all memory pins that may affect memory test to enable seamless integration of Test • Pin Information • Pin Name • Pin Range [L..R] • Direction (Input, Output, InOut) • Logical Port relationship • Polarity (Active High/Low) • Pin Function Data, Address, BistClock, ReadEnable, WriteEnable, ReadWriteEnable, MasterClock, BistEnable, SlaveClock, ScanClock, GroupWriteEnable, GroupReadWriteEnable, (None), Open, OutputEnable, ScanTest, ByPassEnable, MemSelect, ShiftEnable, Active, CAS, RAS, Refresh, ECCDisable, PipelineEnable, [User defined], CAMComparandInput, CAMComparandMask, CAMCompareEnable, CAMMatchOutput, CAMMatch, CAMMultiHit, CAMMatchAddress; ECCEnable, ECCTestInput, ECCDataOutput, ECCOuputEnable, <Repair Related Functions>, <Timing Margin Related Functions>, <ECC Correction>, <ECC Error>, <Power Down Functions>, <CAM Reset>, <Scan Clock Enable>, <Sync bypass Clock>, <MRAMs pin functions>, <Flash Memory Pin Functions>, <External memory pins>, <NVM pins>, • Mile Stone: Draft Document by Feb 2007 (first draft completed in March 2007) • Converted to IEEE standard format: May 2007
Pin Level Functions • Reusing existing Datatypes (21) • MemoryData, MemoryAddress, CoreSelect, OutEnable, MasterClock, MemoryWrite, MemoryRead, ScanMasterClock, ScanSlaveClock, ScanEnable, ScanDataIn, ScanDataOut, In, Out, InOut, Constant, TestData, TestControl, UnusedDuringTest, Row, Column. • Can use more than one type to define a pin function
Pin Level Functions • New types introduced in 2007-08 (23) • ScanBypassClock, ColumnAddressSelect, RowAddressSelect, RefreshClock, RefreshClockSelect, ECCEnable, ECCData, ColumnRepairEnable, RowRepairEnable, ColumnRepairData, RowRepairData, TimingMarginSelect, AsyncWriteThrough, GroupWriteEnable, ScanTest, CAMCompareandInput, CAMCompareandMask, CAMCompareEnable, CAMMatchOutput, CAMMatch, CAMMultiHit, CAMMatchAddress, CAMReset. • New Keyword in relation block • WriteEnableMap
Pin Level Functions • New types introduced in 2009 (25) • SyncWriteThru, MemoryClock, RepairData, RepairReset, RepairClock, MemoryReset, FIFOEmpty, FIFOFull, EdgeTrigger, LevelSensitive, Sleep, TestPowerSave, Standby, PowerModeSelect, DVPM, DataReady, PipelineEnable, MemoryBypass, MemoryDebug, SelfTimeDebug, OscOut, TestOut, RedundancyUse, RepairDone, MemoryInit
Pin Level Functions • New types to be defined • Open, Active, ECCOutputEnable, <Power pins>, <MRAM pins>, <Flash memory pins>, <External memory pins>, <NV memory pins>
