GDS2ASCII Revision History

Version 1.93 09-14-2022

Added support for non-conventional UNIT specification, e.g. user grid 0.001 and DB 5e-10 meters. Now it tries to find the most likely UNIT specification and changes the user grid appropriately. The new ASCII outputs will note this condition.

OASIS output from GDS2ASCII now "autoscales" to accommodate non-micron GDS files.

VS 2015 64 bit build.

A new utility, instance_finder64.exe, (licensed separately) allows the user to export a text file with all the insertion points of a specific cell (or cells) name listed by the user on the command line (or in a file). Supports both a list of cell names or a regular expression.
