The CadEnhance Symbol Description Language (SDL) enables the user to describe the layout of pins and symbols at a very high level. It supports looping constructs and pin-name pattern matching which enables features designers haven't seen before in symbol creation tools. For example using one 45 line SDL file, you can create the symbol files for ANY FPGA in the Xilinx Virtex7 part family (some with over 2000 pins), and similar SDL files will provide support for Altera(Intel) and Lattice part families. While very powerful, the SDL is also very intuitive and simple to create.
In these pages, we will cover the syntax and structure of the SDL, but in order to remove the intimidation factor, we will first show a simple Example
