Next Steps

• LVS (Open source)

  • Extract SPICE file from 10T_32x32_magic.mag.
  • Extract SPICE file from 10T_32x32_xschem.sch.
  • Run the script: runlvs_single.sh (Might have to look at the script and figure out what files need to be where).
  • It will print a .out file.

• Extract GDS file (Magic)

  • Pull up 10T_32x32_magic.mag in magic.
  • In the magic terminal type: "gds".
  • That extracts the GDS file.

• Extract LEF file (NDA Flow)

  • There is a flow to do this in Abstract.
  • This needs all GDS files of layouts we want to use in synthesis and PnR.
  • Outputs a ".lef" file.

• Liberty Characterization (NDA Flow)

  • This needs SPICE files of our layout (i.e. SRAM) and the SPICE files of the SKY130 models (i.e. sky130_fd_pr__.....)
  • This gives timing and power characteristics of the layout/cell.
  • Outputs a ".lib" file needed for synth and PnR.

• Synthesis (NDA Flow)

  • We need the Verilog files for design we want to make.
  • We need the Liberty file for our standard cell library so that it can make a "gate level" netlist of the design.
  • Will give us timing and power metrics of the design using our cells.
  • This produces a lot of files.

• Place and Route (NDA Flow)

  • This needs SPICE, LEF, GDS, LIB, Output from Synthesis.
  • This also outputs a bunch of files.
  • Our end goal is to have a GDS file of our placed and routed design.
  • "signoff.gds"
