Peardrop Design Systems
Glade (Gds, Lef And Def Editor), is a freeware IC editor from Peardrop Design Systems capable of reading and writing common EDA formats and generating symbols and schematics with customisable netlisting. It can load and display large design databases with its fast, lightweight object-oriented database - for example load a 677,000 net / 482,000 special net / 1,210,000 instance LEF/DEF design in 880Mb memory in 72 seconds on a 3GHz PC. Or load a 1.5Gb GDS2 file in 40 seconds. Released now for over 10 years, Glade was the first free layout editor available for Windows. Glade uses the Qt cross-platform GUI toolkit for a modern GUI and uses OpenGL for hardware accelerated graphics when available to give vastly superior display speeds compared to other layout editors, falling back to software rendering only if you do not have suitable hardware. Glade is extendable using Python scripting, allowing access to the database and gui via SWIG wrapping of C++ functions.
Glade is currently built and available for Windows, Linux and Mac OS X using the Qt gui toolkit. So it will run on your laptop or office servers. Other platforms may be supported depending on demand.
