Looking CalTech Interchange Format Syntax.

Hi all,

Does CalTech Interchange Format (CIF) has BNF on the Internet? If so,
could someone give me the link, please? Thanks.

I am requested to write a program to convert GDSII to CIF and vice
versa for layout automation software. That's why I am looking for CIF
BNF.

According to the Cadence Sourcelink, you are right. CIF stands for
CalTech Intermediate Format. I found the websites prior to posting my
question. Unfortunately, those information could not help me to much to
start my project.

 

Thank you for the information. We know CIF/GDSII conversion tools are
available in the market. Unfortunately, some of them cannot integrate
into our design flow environment. In my company, we use many EDA tools
from different vendors. All EDA tools have been customized to suit our
design flow environment here.

In my layout automation team, we have only 3 engineers customized
layout automation tools. To make the matter worse, all of us have
different education and working experience. None of us knows have solid
understand about GDSII and CIF formats. My project leader thought it
was easy to implement it. I only knew the difficulty after I read
through the CNF slides yesterday.

Anyway, I am really appreciated all your helps. I had learned a lot
from the GDSII and it is good for me to understand how software
developers handle shapes, graphics and etc in binary files.
