Cadence SKILL
Template:Short description Template:More footnotes needed Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters". SKILL is a Lisp dialect used as a scripting language and PCell (parameterized cells) description language used in many electronic design automation (EDA) software suites by Cadence Design Systems. It was originally put forth in an Institute of Electrical and Electronics Engineers (IEEE) paper in 1990.[1]
History
SKILL was originally based on a flavor of Lisp called Franz Lisp created at University of California, Berkeley by the students of Professor Richard J. Fateman. SKILL is not an acronym; it is a name. For trademark reasons Cadence prefers it be capitalized.[2]
Franz Lisp and all other flavors of LISP were eventually superseded by an ANSI standard for Common Lisp. Historically, SKILL was known as IL. SKILL was a library of IL functions. The name was originally an initialism for Silicon Compiler Interface Language (SCIL), pronounced "SKIL", which then morphed into "SKILL", a plain English word that was easier for everyone to remember.
"IL" was only Interface Language. Although SKILL was used initially to describe the application programming interface (API) rather than the language, the snappier name stuck. The name IL remains a common file extension used for SKILL code .il designating that the code contained in the file has lisp-2 semantics. Another possible file extension is .ils, designating that the content has lisp-1 semantics.
