Slam is a mature IC Layout editor with the ability to edit very large designs (such as stream files larger than 10GB). Novel features include threading for redraw, support for displaying on multiple X servers simultaneously, and a Tcl interface to the database for user extensibility. The system is a library based system with multi-user support. Programmable structures (P-Cells) are available in Tcl. The editor includes gds input and output. License: Other/Proprietary License with Free Trial Changes: This minor update adds support for 8 button mice, default commands, selection by case-insensitive pattern matching, revision tracking for library and cell changes, and an update to the prompt displaying the level and type of nesting. Point deselect was accelerated when millions of objects are selected, and a new select command has been added to dismiss all objects after selecting a new one. The create via by box command has been enhanced to support via families.
