Please pardon the somewhat spammy post but a Cadence employee suggested that I announce the DesignTools project here.
The DesignTools project contains open source EDA, CAD and CAM tools. The first initial release contains two programs along with their supporting libraries and utilities, all of which are specific to Cadence PCB Editor (Allegro).
Like any open source project, as time and resources allow, more programs and libraries will be added.
Your post is non-descriptive. What do you offer without me having to surf your site to find out?
