  • Si2 Speakers: EDA Standards Must Address Systems, Software

    Who says standards are dull? The 15 th Silicon Integration Initiative (Si2) OpenAccess Conference opened Oct. 20 with a rousing call to action by two speakers - a call to think beyond the traditional boundaries of EDA, and to include systems and software when it comes to standards. At the same time,...

  • Seven Requirements For An Open PDK Standard

    My May 13 blog discussed the significance of the Silicon Integration Initiative (Si2) OpenPDK Coalition , which is seeking to define an open standard that will allow foundries to create a single process design kit (PDK) representation that can be translated into different input formats. What is necessary...

  • What OpenPDK Is And Why It’s Important

    Since process development kits (PDKs) are necessary for all IC design, a major change in the way foundry PDKs are provided is significant news. Such change may be forthcoming from the Silicon Integration Initiative (Si2) OpenPDK Coalition , which announced 10 founding members, including Cadence, May...

  • Re: Using OA for netlisting

    Hello Heinz, I would have thought that the answer is "no", since I believe that the data.dm file is proprietary - certainly CDF is specific to Cadence, and, like Andrew said, if there is no CDF API, then you will need to try to intrepret the information yourself. I could be wrong, someone else...

  • Using OA for netlisting

    Hello, I want to use OpenAccess to do my own netlisting. Accessing connectivity data is no problem. Is there a way to access CDF information like attribute mapping, port sequencing and model type ? Regards

  • Re: import OpenAccess to Cadence Virtuoso and do LVS check

    Hi Quek, My problem is like this: I design a parameterized cell layout with certain technology in PyCell Studio which uses OpenAccess. But PyCell doesn't have the built-in function to do LVS check. So I am wondering if I can do it in Cadence instead, but don't know how to do it exactly. There...

  • import OpenAccess to Cadence Virtuoso and do LVS check

    Hello everyone, I design a layout with a third-party software (PyCell) which uses OpenAccess. Now I would like to do LVS check in Cadence. My plan is first import the generated oa database file into Virtuoso and use the built-in function to do LVS. But I have some difficulties in doing that. Could anyone...

  • OpenAccess – So Much To Celebrate, So Much To Do

    Two distinct messages emerged from the Silicon Integration Initiative (Si2) OpenAccess Conference last week. One is that the OpenAccess database is a great EDA standards success story, perhaps the biggest such story of all. Another is that there’s still a lot of work to do so OpenAccess can offer...

  • Re: Opening a 6.1 schematic in ver. 5.1.41

    Hi Lawrence, IC61x does open the existing design which has a cds.lib file so yes, what you say is true. However, the -cdslibpath option doesn't support cds.lib. There may be some env variable that can be changed to disable this. I tried creating my own lib.defs file and it seems to get to the next...

  • Re: Opening a 6.1 schematic in ver. 5.1.41

    Thanks, Lawrence! I am trying to use oa2cdb. I suppose oa2cdb converts OA 2.2 to cdb as it looks for lib.defs file. The library I am trying to convert is still defined in a cds.lib file so I assume this is OA 2.0. What can be done in this case? Regards, Mandar
