Release 1.2.0

2021-03-17 1.2.0

Known bugs:

• The executable version of betterSIS (both the deb package and the PyInstaller executable) can't correctly connect to Github Release to check for updates (SSL verification error)

  This will be fixed in the next version (for now you need to manually check if an update is available)

Features:

• Added the ls command: it shows files and directories in the given/current path

• Added the cd command: you can use it to navigate directories from betterSIS

• Added the edit command: opens the specified file with a simple text editor

  Editor's features: syntax highlighting, basic edit/save functionality, use the tab key to write/complete keywords

• (siswrapper feature) Added bsis_script command. Its accepted parameters are:

  • fsm_autoencoding_area, useful for FSM circuits: minimizes states, automatically encodes states, optimizes area and maps the circuit by area (synch library)

    Executed commands: state_minimize stamina, state_assign jedi, source script.rugged, read_library synch.genlib, map -m 0 -W -s

  • fsm_autoencoding_delay, useful for FSM circuits: minimizes states, automatically encodes states, optimizes delay and maps the circuit by delay (synch library)

    Executed commands: state_minimize stamina, state_assign jedi, reduce_depth, source script.rugged, read_library synch.genlib, map -n 1 -W -s

  • fsm_area, useful for FSM circuits: minimizes states, uses manual states encoding, optimizes area and maps the circuit by area (synch library)

    Executed commands: state_minimize stamina, stg_to_network, source script.rugged, read_library synch.genlib, map -m 0 -W -s

  • fsm_delay, useful for FSM circuits: minimizes states, uses manual states encoding, optimizes delay and maps the circuit by delay (synch library)

    Executed commands: state_minimize stamina, stg_to_network, reduce_depth, source script.rugged, read_library synch.genlib, map -n 1 -W -s

  • lgate_area_mcnc, useful for combinational circuits: optimizes area and maps the circuit by area (mcnc library)

    Executed commands: source script.rugged, read_library mcnc.genlib, map -m 0 -W -s

  • lgate_delay_mcnc, useful for combinational circuits: optimizes delay and maps the circuit by delay (mcnc library)

    Executed commands: reduce_depth, source script.rugged, read_library mcnc.genlib, map -n 1 -W -s

  • lgate_area_synch, useful for combinational circuits: optimizes area and maps the circuit by area (synch library)

    Executed commands: source script.rugged, read_library synch.genlib, map -m 0 -W -s

  • lgate_delay_synch, useful for combinational circuits: optimizes delay and maps the circuit by delay (synch library)

    Executed commands: reduce_depth, source script.rugged, read_library synch.genlib, map -n 1 -W -s

  • fsmd_area, useful for FSMD circuits (circuits which include datapaths and an FSM): optimizes area and maps the circuit by area (synch library)

    Executed commands: source script.rugged, read_library synch.genlib, map -m 0 -W -s

  • fsmd_delay, useful for FSMD circuits (circuits which include datapaths and an FSM): optimizes delay and maps the circuit by delay (synch library)

    Executed commands: reduce_depth, source script.rugged, read_library synch.genlib, map -n 1 -W -s

  This command also shows which command is executed and the statistics after some commands

  Partial and full results are written to new BLIF files.

  WARNING! These commands are executed in this order, thus does NOT guarantee the best result: multi-level minimization is not perfect!
  to obtain better results you should try to execute these commands manually in a diffent order (try also to execute them more than once)

• (siswrapper feature) Now this library verifies if the stg_to_network command is successful

Fixes:

• (siswrapper fix) Now the write_eqn command gives the expected result when used to output to a file.

  Before this fix the write_blif method was executed instead of the correct method

• (siswrapper fix) When SIS is not installed the error message shows exactly what the problem is
• (siswrapper fix) If you call the write_eqn and write_blif method without parameters the output doesn't contain the command.
• (siswrapper fix) Can't execute the rugged script if no file as been read with a read command
• (siswrapper fix) When you execute a read command, this library calls the reset method to close the SIS session and
  open a new session inside the folder of the input file

  This "fixes" the ".search x file not found" error when you try to read a file that is in another folder and contains the .search keyword.

  This error was normal but not intuitive (because the imported file was present inside the same folder as the input file but not inside the current folder).
  It was the original SIS behaviour.

• (siswrapper fix) The output of the print_stats command couldn't be intepreted as correct when the circuit had more than a 10000 literals/states

  The output was correct but the program reported it as an error
