Pin level functions

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 functions1

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 functions2

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 functions3

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 functions4

Pin Level Functions

  • New types to be defined

    • Open, Active, ECCOutputEnable, <Power pins>, <MRAM pins>, <Flash memory pins>, <External memory pins>, <NV memory pins>
