One simple way to solve this is use vcs -full64 if sqlite libraries are of 64bit. Hi Adiel

For instance VCS has a C and a TCL API into these databases. The databases themselves are optimized for storage and performance, and may not be implemented as an SQL database. There are also efforts afoot to have standardized API access to coverage databases. I've seen many users using the API to access these databases, and populate an SQL database with interesting (to them) stuff derived from these databases. I see you have described the challenges in your linked presentation. thanks for the comment. badri hi Rahul,

Can the functional and code coverage database can be queried along with the performance database? The challenges which we are facing is to collect the required data at a central place and analyze it. This includes, performance, functional coverage, bugs, passing and failing test count and any other information. Currently we have written scripts which acts like a glue logic to integrate various parameter which we need, to check the status of verification progress. I have described the challenges as verification management in one of the article http://www.nxtbook.com/nxtbooks/emedia/eetindia_20081016/#/0 I am looking forward for your next blog, but I think the step towards getting the information in SQL with so much of flexibility in term of the access to the internal tables will be great help moving forward. Regards, Rahul Badri,

Yes, the table schema is visible, and extensible to add your custom entries in the database tables. I will put more details in my next blog item. Its all in the user guide as well. Feel free to ask other questions or provide other feedback, i will try to address them in the next blog post. Badri Hi Rahul,
