Criticisms:

“It's too complex”

“EDA industry won't support it”

“Nice vision, but it will never work”

“Digital, maybe... analog, no way”


January 2003: OpenAccess v2 Source Code Released


OpenAccess “Promotions” Circa 2003

Open AccessData Base

MASKS

● No File Exchanges

● Native OA or Data Exchange can work for “point tools”

● Tightly integrated capabilities would require Native OA

– “Compatibility Layer” for IBM tools

Mfg Line data

- Design / process interaction..

- DFM / DFY

- Etc.

Selecting OA as our data model

We looked at 15 other data models (internal, external, open source) before choosing OA.

Things that appealed to us about OA:

Free translators to and from OA (GDS, LEF/DEF, Verilog, etc.).

The relative ease of moving from CDBA to OA.

The ability to influence the direction of OA development.

Open standard (can work with universities and vendors).

Accessible source.

Rich documentation and training.
