vManager Reborn

Metric driven design verification has finally come into its own. As I reported last year at DAC, almost all branches of chip engineering are getting into the game. I saw metric driven physical design tools, metric driven functional verification tools, and metric driven synthesis tools. While this is great news and I’ve always been a big proponent of the metric driven methodology, there’s been a problem right from the start. Our chip design projects have generated ‘big data’ quantities of output since way before big data was cool.

Cadence took a step towards addressing that issue this week with the release of the newest version of vManager, (that’s right, it’s called vManager again). The tool looks similar to previous versions from a UI perspective prompting some industry pundits to wonder what the difference is. The difference lies in the innards, you know, the engines. The backbone of vManager now consists of a PostgresSQL database. This new workhorse under the covers enables vManager to handle terabytes of data and hundreds of simultaneous users. The new technology finally promises the processing power that we’ve needed to make optimal use of the data that’s been available to verification projects for years , but which has sadly been forced to sit on the sidelines because of our inability to analyse it.

Another notable feature of the new vManager is that its begun to incorporate engineering communications.  Engineers can now record notes and tasks for other engineers on the team. With verification teams easily running as large as 70 engineers and not too infrequently over 100 engineers, this new capability should be able to provide a more seamless communication path as well as a paper trail, (bit trail?), of what’s going on in the project.

While the UI will seem familiar to legacy vManager users, it has also been updated from it’s e language roots to Java. This brings up a slightly unrelated question I have for all the other verification engineers out there. Has anyone else ever squinted at the e language and got the impression that they were looking at Java with the JAspect package attached and a slight dusting of JNI, (the Java Native language Interface)?

The newest installment of vManager is being announced on the tenth anniversary of the original vManager release. I might get to take a test drive soon. In all likelihood, you can get a look at the newest tech even sooner by hitting up your local AE and sales team.
