We are working on a chip design project and need to convert files from a GDS2 format (generated by Calma, a GE company) to CIF, a standard developed by Cal Tech. Any leads or code would be appreciated. -- Richard W. Webb ESL Incorporated ARPA: rww%esl@lll-lcc.ARPA SMAIL: rww@esl.ESL.COM

However I can give you some possible contacts that may get you started in the right direction: OCTAL, INCORPORATED 450 East Middlefield Rd. Mountain View, CA 94043 (415) 962-8080 They had a working version as recently as June 11, 1985. Also try: NCA CORPORATION 388 Oakmead Parkway Synnyvale, CA. 94086 (408) 245-7990 The address and phone may be out of date, but they should be able to help you. If by some chance you can get a copy of the code to a CIF to/from CALMA GDS2 converter for free, would you please mail it to me. I hope this helps.........good luck.

If you have Magic, from the Berkeley CAD tools distribution, you can enter Magic and type (I haven't tried it, but this is the approximate form): :calma read oldfile :cif write newfile Steve Schoettler

If your design contains any oblique angles at all, you will need to find a different solution. -- Howard A.
