When reading about technology, you gotta love the file acronyms that start flying faster than meatballs in a food fight. While parsing the news on Siloti’s latest release, I tried to do some internet research on their “FSDB” file, which was in their presentation slides.

Not much came up on a Google search. The closest thing was a “flatfile streaming database” which was used for medium-sized outputs and, being ASCII-based, could be easily plumbed to look at the results. Even though the “medium” thing made me a bit suspicious, it was the closest match so far.

But I kept looking. You could find the phrase “FSDB” all over the place, but nowhere did it actually say what it was. Wikipedia has an article with a long list of file formats for many uses, including CAD and EDA. FSDB isn’t in there.

I also got a bit suspicious when I saw another reference to an FSDB file being binary: that didn’t sound like the ASCII FSDB I had run across. (There were a couple other uses that were technical, but clearly off the mark.)

I got ready to send an email in to get clarification from SpringSoft, but I decided to check out their other filenames first just in case I needed more than one answer. And, in a search for their “KDB” I ran into a page that had a nice definition of them both – and it was on a SpringSoft page.

I further slapped my head when I realized that the “binary” references I had noticed earlier had been in a Novas context, which is the outer shell of the obligatory EDA branding scheme (which requires brands wrapping brands wrapping brands). I was thinking Verdi and Siloti, but those are subsumed under Novas. Doh!

So I didn’t have to send the email.

I felt even more stupid when I re-read the press release. There it was, in black and white.

So… for the record, they use the following files in the whole Siloti/Verdi thing:
- FSDB: fast signal database (the simulation results)
- KDB: knowledge database (the structure of the design)
- BDB: behavior database (gleaned through analysis)
- ESDB: essential signal database (established through analysis)
- ES FSDB: the FSDB of the essential signals

PS Outside our nerdly realm, the most relevant meaning of FSDB, according to Google, is Florida School for the Deaf and Blind.
