ECO ( Engineering Change Order ) is Dorado's corporate commiment to the semiconductor industry.
ECO has long been considered as activities related to design change of integrated circuits. Dorado expands the scope of ECO to include “all the incremental jobs in the ECO Phase of design flow”, and commit to provide solutions for all ECO issues.
Dorado’s Tweaker is an ECO tool suite that supports all possible incremental jobs such as Functional ECO, Metal ECO, Timing ECO, Power ECO, and Clock ECO. Tweaker has been built to meet the requirement of incremental jobs with ECO specific architecture and algorithm. It's the first EDA tool designed specifically for ECO which integrates front-end/back-end design information into one multi-view system. It supports 40nm design and below.
