What is ViVA of Cadence ?
Jan 17th, 2009, 6:26am
 
Some Cadence guys in this forum, e.g. sheldon, Andrew Beckett refer "ViVA".
What is ViVA ? What is abbreviated as "ViVa" ?
http://en.wikipedia.org/wiki/Vive,_Viva

"ViVa" is a waveform viewer ?
If so, Cadence have new waveform viewer without fixing many bugs of wavescan.

Wavescan will be abandoned as same as AWD after a release of Wavescan ?

ViVA stands for Virtuoso Visualisation and Analysis. It's the waveform tool in the IC613 release.

It's not a whole new waveform tool; it's based upon wavescan, but as part of our ongoing improvements, various parts of it are being re-implemented in Qt, to allow tighter integration with the rest of the IC61 tools. Currently the calculator and results browsers have been reimplemented in Qt (the modern widget set and user interface used in IC61), but the graph is essentially the same as the IC5141 wavescan graph - note that there have been a lot of improvements in that over time too.

Ultimately the graph will also be reimplemented in Qt. There are lots of benefits of doing this - it will allow graphs to be embedded in lots of other places in the tools, which is not possible with the current Java implementation - things like being able to have waveforms in tabs alongside your schematics and ADE XL views, etc, etc.

So it is not a matter of abandoning wavescan, but an evolution of wavescan - fixing issues and improving it as we go along. This reimplementation will allow tightening of the interfaces between the parts of the tools; wavescan was originally a standalone tool for command line spectre users, and was then used as an AWD replacement (and AWD definitely needing replacing because it was very elderly and quite limited in how it could be extended), so much of the work has been in making a peg of one shape fit into a hole of a slightly different shape.

Regards,

Andrew.

Replacement of Java to Qt is good improvement, I think.
