Cadence Library Directory


Here is a brief description of each cellview. These directory includes everything needed to run virtuoso. There are also png files In each cellview if you with to view the schematic and the layout, under the schematic, symbol, or layout folder.

  1. test_sram_6t_sleep - the simulation schematic for testing the general functionality of 6TDPMTSRAM cell
  2. test_sram_6t_sleep_test2 - the simulation schematic for testing if the 6TDPMTSRAM cell will retain it's internal value when in sleep mode
  3. 2_1_mux - the schematic of the MUX used in the above two testing schematics. Not used in any project schematics
  4. inverter - the schematic and layout of the inverter used within the LS38Decoder design
  5. LS38Decoder - the schematic and layout of the 3:8 Decoder used in the final SRAM array
  6. inverter2 - the schematic and layout of the invert used in the final SRAM array (different layout than the first inverter for design reasons
  7. 8x8PRECHARGE - the schematic and layout of the 8x1 array of Precharge circuitry used in the final design
  8. 6TDPMTSRAM - the schematic and layout of the single SRAM cell used in the finall design
  9. 8x8PRECH_WRITECIRC - the schematic and layout of the 8x1 precharge circuitry combined with the 8x1 write-circuitry lock settings. Ignore this file
  10. 8x8SENSE_PRECH_WRITECIRC2 - the schematic and layout of the 8x1 Precharge, write-circuitry, and sense amplifier
  11. 8x8SENSE_AMP - the schematic and layout of the 8x1 Sense Amplifier
  12. 8x8SRAM - the schematic and layout of the 8x8 array of SRAM cells
  13. 8x8SRAM_PRECH_SENSE_WRITE - the schematic and layout of the 8x8SRAM array, precharge, write-circuitry, and the sense amplifier
  14. 8x8WRITE_CIRCUITRY - the schematic and layout of the 8x1 write-circuitry
  15. PRE_CHARGE - the schematic and layout of a single precharge circuit
  16. WRITE_CIRCUITRY - the schematic and layout of the single Write-Circuitry
  17. SENSE_AMP - the schematic and layout of the single sense amplifier
  18. SAIRS - the schematic and layout of the final SRAM array design (64bitLPSRAM)
  19. sim_sairs - the simulation schematic of the final SRAM array design

The most important cellview is SAIRS, which is the final design. All other cellviews are either simulation schematics, or components/modules that make up the final design, in which SAIRS is dependent on.
