EDIF was mainly supported by the electronics design end-users, and their companies. The EDA vendors were involved also, but their motivation was more along the lines of wanting to not alienate their customers. Most of the EDA vendors produced EDIF 2 0 0 translators, but they were definitely more interested in generating high-quality EDIF readers, and they had absolutely no motivation at all to write any software that generated EDIF (an EDIF Writer), beyond threats from customers of mass migration to another vendor's software.
