  1. October 2010 Precision Synthesis status

  2. Precision 2010a update1 Prod (1/2) • Beta version released end August • FGEN2 (3 inputs, 2 outputs) lib introduction • Replicate function (max fanout) • New ATF280E variables introduction • IO pads with registers • IBUFR, OBUFR, OBUFER, BIBUFRI, BIBUFRO, BIBUFRR • Twice more combinatorial cells than AT40K • GCLKBUF automatically inserted on input pad clock • New Wire Load Models (more accurate)

  3. Precision 2010a update1 Prod (2/2) • BUFZ (internal tristate buffer) automatically inserted • FDE (register with enable) automatically inserted • Additional comment : LPM macros not included in percentage of utilization • INV cells included in area summary • Timing regression (since 2009.95) corrected

  4. Next Precision 2010a update2 (1/2) • End of 2010 or early 2011 • FA (full adder) & MULT (multiplier) lib introduction vs LPM blocks (in option) • FGEN2 improvement • ROM LPM oversize => crash in IDS • address width 10 • New ATF280E variables definitions and documentations • Specific switch to forbid the use of a given macro • Specific switch to activate Replicate

  5. Next Precision 2010a update2 (2/2) • ‘set_input_transition’ correction and documentation • ‘report_io_register’ command • GCLKBUF included in area report • 64 bits Linux version

  6. Next Precision 2010a update3 • ‘set_input_transition’ correction and documentation • ‘report_io_register’ command • GCLKBUF included in area report • 64 bits Linux version • Precision ATFS450

  7. Others requests • RSBUF automatically inserted on input pad reset • Dynamic macros FGEN1*, FGEN2*, MGEN* • Atmel must verify the full flow before • LPM Carry Select Adder • LPM Mux • ‘set_load’ command introduction • New packages • …
