A console program to synthesize new layers based on an expression involving boolean operations between existing layers

Command-line Reference

layersynthapp64.exe 
  +input:{input-gdsii-oasis-dbload-file} 
  +outdir:{directory-for-output-files}
  +layerspec:{layersynth-spec}
  {WINDOW SPEC}
  [{MISC OPTIONS}]

Required

+input:{input-gdsii-oasis-dbload-file}

• Specify the path to a valid GDSII/OASIS or DBLOAD file

+outdir:{directory-for-output-files}

• Specify an exisiting directory where the output file will be created

+layerspec:{layersynth-spec}

• Expression for layer synthesis
• See here for complete syntax

WINDOW SPEC

• Specify at least ONE of the following

-window:LLUR,{filename}:{llx},{lly},{urx},{ury}

• Specify a window using it's lower left and upper right co-ordinates (in file units)
• The filename is used to identify the window and the file generated thereof
• Final output path = {output-dir} + {filename} + {extension}

-window:LLWH,{filename}:{llx},{lly},{width},{height}

• Specify a window using it's lower left co-ordinates, width and height (in file units)
• The filename is used to identify the window and the file generated thereof
• Final output path = {output-dir} + {filename} + {extension}

-window:CWH,{filename}:{cx},{cy},{width},{height}

• Specify a window using it's center co-ordinates, width and height (in file units)
• The filename is used to identify the window and the file generated thereof
• Final output path = {output-dir} + {filename} + {extension}

@windows:LLUR,{filename}:{window-list-file}

• Read a set of windows from a text file located at {window-list-file}
• Each line in that file specifies a single window as {LLX},{LLY},{URX},{URY} (in file units)
• Lines beginning with a # are treated as comments
• The filename is used to identify the windows and the files generated thereof
• Final output path = {output-dir} + {filename} + {line_num} + {extension}

@windows:WHLL,{filename}:{window-list-file}

• Read a set of windows from a text file located at {window-list-file}
• The first line specifies the {WIDTH},{HEIGHT} (in file units) to be used for all windows
• Each subsequent line in that file specifies the lower left co-ordinate (in file units) where a single window is to be placed
• Lines beginning with a # are treated as comments
• The filename is used to identify the windows and the files generated thereof
• Final output path = {output-dir} + {filename} + { line_num } + {extension}

@windows:WGC,{filename}:{window-list-file}

• Read a set of windows from a text file located at {window-list-file}
• The first line specifies the {WIDTH},{HEIGHT} (in file units) to be used for all windows
• Each subsequent line in that file specifies the co-ordinates a point (in file units) where the center of a window is to be placed
• Lines beginning with a # are treated as comments
• The filename is used to identify the windows and the files generated thereof
• Final output path = {output-dir} + {filename} + { line_num } + {extension}

-tiles:RXY,{filename}:{roi_llx},{roi_lly},{roi_urx},{roi_ury}:{nx},{ny}[:{i},{j}]*

• Generate {nx} x {ny} same sized tiles from a region defined by it's lower left and upper right co-ordinates (in file units)
• Optionally, if a set of {i},{j} tile positions (1 {= i {= nx and 1 {= j {= ny)are specified, only those tiles will be extracted. Otherwise, all tiles will be extracted
• The filename is used to identify the windows and the files generated thereof
• Final output path = {output-dir} + {filename} + {i}.{j} + {extension}

-tiles:RWH,{filename}:{roi_llx},{roi_lly},{roi_urx},{roi_ury}:{width},{height}[:{i},{j}]*

• Generate {WIDTH} x {HEIGHT} same sized tiles from a region defined by it's lower left and upper right co-ordinates (in file units)
• Optionally, if a set of {i},{j} tile positions (1 <= i <= Num. tiles in X and 1 <= j <= Num. tiles in Y)are specified, only those tiles will be extracted. Otherwise, all tiles will be extracted
• The filename is used to identify the windows and the files generated thereof
• Final output path = {output-dir} + {filename} + {i}.{j} + {extension}

-tiles:WHC,{filename}:{width},{height}[:{cx},{cy}]+

• Generate {WIDTH} x {HEIGHT} sized tiles centered at one or more co-ordinates
• The filename is used to identify the windows and the files generated thereof
• Final output path = {output-dir} + {filename} + {COUNTER} + {extension}

MISC OPTIONS

-cell::{view-cell-name}

• Set the view cell
• Default: Deepest root cell in the file

-diskload

• If specified, the file is accessed from the disk for all operations
• Default: File is loaded to memory

-thrnum:{n-synthesizer-threads}

• Specify the number of threads to be used for boolean operations
• Default: No. CPU cores

-noclip

• If specified, polygons will not be clipped at window extents
• Default: Polygons are clipped at the window extents

-log:${new_log_file}] || [-log+:${log_file}

• Create an execution log at the specified path (including file name). The directory component of the path must exist with suitable write permissions
• By default, no log is created
• If -log+ is used, an existing file at that path will be appended. With -log, an existing file will be overwritten

-silent

• If used, no messages are written to stdout/stderr
• If not used (by default), the execution log is written to stdout and error warning messages are written to stderr
