Parametric layout generator for digital, analog and mixed-signal integrated circuits
First , I have made the program and pointed my PATH to the directory, the result is as follows: please see Fig 1 &2 . When I type “opc --technology...
Some cells (such as the spiral inductor using arbitrary-angle paths) generate polygon with a lot of points, usually too much for some tools (GDS allows only shapes with less than...
Most importantly polygon union (or) is needed in order to reduce shape complexity/count in cells.
The code provides some basic drawing functions such as rectangles, but it relies on the existance of cell generators. These need to be written. Anything that is needed for layout...
Currently, only an interface to cadence virtuoso is provided. It is pretty easy to write these interfaces, as they only have to call the main.lua with the correct cell, retrieve...
Hey there, in "cells/logic/counter.lua" I noticed this comment: "The counter is down-counting, since this can be implemented more regularly than an upcounting counter. (At least that's what I think, if...
