1980's: The Second Generation An Integration-Centric View of CAD
Integrated multi-tool (CAE) systems were the focus.
Towards the end of the decade, development of framework-based integration-oriented standards began (e.g. CFI, CFL)
Relatively large CAD vendors evolved to dominate the CAD systems business (e.g. Mentor, Cadence, Valid)
Virtually every successful product was initiated by a person or team that used to be designers.
