Difference between SKILL and RAVEL

SKILL provides a safe, high-level programming environment that automatically handles many traditional system programming operations, such as memory management. SKILL programs can be immediately executed in the Cadence environment. The SKILL programming language lets you customize and extend your design environment. SKILL is ideal for rapid prototyping.

RAVEL is a language to implement design rules for PCB and Packaging tools. It builds on a relational view of the design data.
