Gemini pin file definition

icjam

I remember using a pin file with Assura's Gemini program to allow pin swappability for subckts but do not remember the format.  Does anyone have an example or know how this file is formatted?  Thank you.

    Thank you Andrew. We will look into the NVN features of Assura directly as that may be easier to use. I know gemini evolved from a program called gemini3 created by BLDA (Bell Labs Design Automation) which was sold to Cadence when they bought BLDA in the late 1990's or early 2000's. It was an SVS tool at that time - we used a program to extract the schematic flat from the layout, then gemini3 to do the SVS - that is the old way of doing an LVS. That is why I remember it, but in a hazy way since it was many years ago. When I was using Assura, a colleague told me that gemini3 was in Assura as "gemini". I used it for some SVS use, but still that was many years ago. I see it has migrated purposes since then.
