Command Line Syntax
BoolCompare is actually a fairly complicated script that uses a combination of BoolQl, BoolMT and gdsfilt to produce the final results. The syntax below is input to the script.
boolcompare <gds_file> <gds_file> [<options>] where gds_file must not be absolute paths. If using two layers contained within the same GDSII file, specify it both as primary and secondary. options include: -layer[s] N,M... include only the indicated layer[s] It is important to use this argument if your input file has many layers; this will reduce memory footprint and load time. -top CellName use CellName as the root cell for XOR -top_primary CellName include CellName from the primary source -top_secondary CellName include CellName from the secondary source -window LLX,LLY,URX,URY process only the specified window -job JobName create and perform XOR in folder named: work.JobName if not present, the default is work.xor -thrnum N limit boolean operations to N threads. If not specified the program will determine the number of cores and use that many concurrent threads. -prescale S increase input database precision by S S is a number greater or equal to 1. A typical value for S is 10. -newgrid G output grid is to be forced to G G is a number less than 1, e.g 0.001 -sliver S drop features in XOR output less than S S is in user units -path do not use simple path model when converting paths to boundaries -view view output on completion; the environment variable $LAYOUT_VIEWER needs to be set
